Tripped breaker alarm?

  • Add to quote

Is there a way to put an alarm on a breaker that would sound when tripped? It's a dedicated circuit for an aerator, so there is no outlet associated with it.  

Fishbulb28

What brand and type of panel is being used? Many breakers can be purchased with either auxiliary or alarm contacts for exactly this purpose.  

Is that a septic aerator? Does it trip frequently? If so, there may be a more pressing issue. Where do you want the alarm, by the panel?  

Yes it is a septic aerator. I would like to have the alarm in the garage, right by the breaker box.

Such a set up would be quite easy ! You just need a contactor and a signal light / siren With power applied to the contactor (load side of breaker) the power to the light would be interrupted, but if breaker opens power to contactor is interrupted and it closes and sends power to signal light. easy as !

https://www.homedepot.com/p/IDEAL-S...er-Failure-6-LED-Safety-Light-SK636/203446030 This will give both , warning of the breaker tripped and lighting when the power goes out. You just need an outlet on the same circuit.  

rjniles

Wire a LED lamp right above the panel and connected to the same breaker. Light out means the breaker is tripped.

Circuit Breaker Tripping: Troubleshooting Guide

circuit breaker trip alarm

Hubert Miles | Licensed Home Inspector, CMI, CPI

Updated on January 5, 2024

breaker test

A circuit breaker tripping results from short circuits, overloaded circuits, and ground faults. In each case, an unintended excessive flow of current triggers the trip. You must reset the circuit breaker by flipping it back on to restore power.

Circuit breakers trip because they cannot handle the amount of current running through them. Tripping the circuit breaker interrupts the flow of electricity and protects your devices or appliances from damage.

Without electrical circuit breakers , the possibility of electrical fires would be much higher.  

This guide looks at what causes circuit breakers to trip, what you can do, and how to identify a bad breaker.

What Would Cause a Circuit Breaker to Trip

There are three leading causes of circuit breaker trips:

  • circuit overload
  • electrical faults (i.e., ground faults and arc faults)
  • short circuits

Below are factors that can cause circuit breaker trips. 

Circuit Overload

A circuit overload happens when the flow of electric current running through the circuit exceeds the amperage of the devices it serves. 

For example, if your microwave is a 12.5 amp appliance, you can run it on a 15 amp circuit. That means your microwave is safe as long as the amperage running through the circuit is 15 amps .

However, if the circuit receives an excessive electrical load over 15 amps , it will automatically trip to protect your device from damage. If the circuit doesn’t trip, the excess current will fry the circuit in your microwave. 

Also, if you operate too many appliances and devices on one circuit, its internal mechanism heats up, causing the breaker to trip. 

Circuit overload is the most common reason for breakers tripping. 

Ground Faults

A ground fault occurs when the active wire comes into contact with a ground wire made of bare copper. Sometimes, this fault may happen when the hot wire touches the metal box connected to the ground wire.

Excessive current flows once the active wire touches the ground wire, flowing into the earth. If you step on the affected area, ground faults can cause shock and even electrocution. The uncontrolled flow of electricity will cause the circuit breaker to trip.

Arc Faults 

An arc fault happens when exposed faulty wiring touches, causing the electric current to arc at the meeting point. As a result, sparks occur, which can ignite an electric fire.

A corroded or loose connection is the main culprit for arc faults. Circuit overloads, ground faults, or short circuits trip an AFCI (Arc Fault Circuit Interrupter) circuit breaker.

Arc faults result from damaged, loose, or corroded terminals and wires. The arc fault builds up over time as the heat due to the cable damage and terminals build up to the point of ignition.

Short Circuits

A short circuit occurs when an active wire touches a neutral wire, and the electrical current takes an unintended path of least resistance. 

The common cause of short circuits is frayed wires coming into contact when the wires touch. The electrical current flow increases significantly, causing the circuit breaker to trip to stop the electricity from damaging appliances.

It is a short circuit because the current bypasses the proper circuit wiring channels and flows through a shorter, unplanned pathway.

Short circuits occur 

  • When insulation melts and wires are exposed
  • Within appliances with damaged internal wiring
  • Due to damaged and frayed extension or appliance cords

How do You Fix a Breaker that Keeps Tripping?

A dedicated circuit breaker tripping indicates too much current flowing through the wiring or connection to the outlet.

Here is a step-by-step guide to follow when you notice the first trip:

  • Begin by turning off all the appliances and unplug electrical devices from the outlet. Also, switch off light fixtures and unplug those that you can. This prevents any appliances from damaged when the breaker is reset and a sudden surge of power comes through.
  • Open the circuit panel or box and locate the on and off buttons of the circuit breaker. You may notice an orange or red color on the breaker when it is off. 
  • Flip the switch from off to on to reset the circuit breaker. Once the breaker is reset, you can switch and test the appliances to see if the electrical power is flowing.
  • Keep safe as you reset the breaker by working from the side of the electrical box instead of the front. That way, you will avoid any sparks (should there be any) when you switch the breaker back on.
  • Some people prefer to switch the main electrical switch when working on the circuit breaker for added safety. 

Types of Circuit Breakers

Standard circuit breaker.

Standard circuit breakers monitor the modulation of the electric current coming into your devices and appliances. 

This circuit breaker stops the current from flowing when it detects the excessive flow of electricity. 

Standard circuit breakers come in two forms:

  • Single-pole circuit breakers
  • Double pole circuit breakers

Single-Pole Circuit Breakers

Single-pole circuit breakers are the most common breakers in homes and buildings. They monitor the electric current’s flow in one wire and trip if that wire experiences a very high influx of electricity.

These breakers deliver only 120 volts and work well for 15 to 30 amp circuits. Single-pole circuit breakers come with one switch in the back. 

Double-Pole Circuit Breakers

The double-pole circuit breakers monitor the current in two wires simultaneously. You will notice two switches on the back of these breakers.

The double-pole circuit breakers will trip even if only one of the wires receives too much current. They can accommodate between 15 to 200 amps while delivering 240 volts. 

Single-pole breakers are a good fit for lighting fixtures and other standard home outlets. On the other hand, double-pole breakers work for larger appliances like dryers and washing machines. 

Ground Fault Circuit Interrupter (GFCI)

The GFCI circuit breaker interrupts the line due to ground faults. They trip when the current starts to follow an uncharted path into the ground. These ground fault surges occur when a foreign conductor, like water, comes in contact with a receptacle .

At the same time, they offer protection against circuit overloads and short circuits. 

GFCI circuit breakers come built into specialized outlets required for wet areas in the home, including :

  • Outdoor areas like the balcony, patio, porches, and decks
  • Laundry rooms
  • Swimming pools
  • Six feet from a sink
  • Six feet from the bathroom

These breakers help prevent shock or electrocution should the electrical outlet contact water. 

Arc Fault Circuit Interrupter (AFCI) 

The AFCI circuit breaker detects normal and abnormal arc faults, so it will trip when it detects a dangerous arc fault that can cause a fire. 

The AFCI circuit breaker doesn’t work to protect devices and appliances plugged into an outlet. It works to prevent electrical fires due to faulty connections and wiring. The internal sensing mechanism in the circuit breaker senses the conditions of an electric arc, and the circuit trips to avoid an electric fire.

AFCI protection can also be built into an outlet. The National Electrical Code (NEC) requires these types of breakers to feature in :

  • Common rooms
  • Laundry areas

AFCI and GFCI circuit breakers can co-exist and complement each other for the best protection.

Combination All Fault Circuit Interrupter (CAFCI)

The CAFCI breaker senses and reacts to any electrical fault, including ground and arc faults.

CAFCI is a relatively new technology that meets new NEC requirements for circuits requiring arc and ground fault protection.

Do Circuit Breakers Get Weak?

A circuit breaker can wear out and become weak. If a breaker trips frequently, the thermal or magnetic element can lose calibration, causing it to trip at lower amp loads than intended. A breaker constantly under thermal stress caused by overloading the circuit will eventually trip more frequently.

Let’s not forget breakers are not impervious to damage. As the internal mechanical parts wear out, they become very sensitive and may not hold under normal load amperage and temperatures.

Electricians refer to this as a bad breaker .

Will a Bad Breaker Keep Tripping

By definition, bad breaker malfunctions, so it will keep tripping until it is either replaced or rectified .

A licensed electrician performs this simple test to see if a breaker will keep tripping and determine if it can be repaired or replaced in the following steps.

  • The electrician will switch off all the fixtures and appliances in the house. Also, unplug everything.
  • Find the malfunctioning circuit breaker . The electrician will go to the electrical box and locate the breaker lighting orange or red or the one with the switch off.
  • They will ascertain that it is the correct circuit breaker. After that, the electrician puts the breaker off.
  • With the switch on, the breaker is back on as well. The electrician will plug the appliances into the outlet with the problem circuit breaker. Now, they will turn the devices and appliances on. 

If the breaker trips, the electrician will investigate the circuit’s current amount. The breaker is bad if the current is according to the appliance’s rating.

How You know if a Circuit Breaker is Bad

Breakers do wear out after a while. It has a problem if the breaker doesn’t stay on after resetting it.

Since the circuit breaker controls the electric flow in the house, it is essential to monitor it and catch signs that it has gone bad early.

Here are key signs that denote a bad circuit breaker :

It Frequently Trips

Frequent tripping could be because of a bad breaker. After tripping and resetting, your circuit breaker should stay on unless it detects high current flow. 

To ensure that the issue is not the electricity but the circuit breaker, call an electrician to examine your electricity’s flow and determine whether it is the cause of the constant tripping.

If it is not, then the circuit breaker is the problem. 

The Breaker Overheats

Electrical systems will heat up when active. Typically a breaker can heat to about 60°C (140°F) before problems arise.

Terminations for standard rated breakers: UL 489 Paragraph 7.1.4.2.2 says the temperature rise on a wiring terminal at a point to which the insulation of a wire is brought up as in actual service shall not exceed 50°C (122°F). Terminations for 100% rated breakers: UL489 Paragraph 7.1.4.3.3 says the temperature rise on the termination shall not exceed 60°C (140°F). Handles, knobs, and other user surfaces: UL489 Paragraph 7.1.4.1.6 says the maximum temperature on handles, knobs, and other surfaces subject to user contact during normal operation shall not exceed 60°C (140°F) on metallic and 85°C (185°F) on nonmetallic surfaces.

Call an electrician immediately if the breaker becomes too hot.

There are Scorch Marks

Scorch marks around receptacles, appliances, and the electrical box should tell you your circuit breaker has gone bad.

The burn marks indicate that wiring insulation has melted off and the circuit wires are now sparking and emanating heat or fire. That means that the circuit breaker did not interrupt the excess current and reached the wires and burned them. 

You may see melted wire sheathing on the wire where it connects to the breaker.

Professional electricians can use a  thermal imaging infrared camera to locate the heat source. The infrared camera allows them to pinpoint the problem area through the walls and other construction material.

A Burning Smell

Sometimes you may smell the insulation burning, but no scorch marks are present to denote which outlet is the problem. 

With the help of the infrared camera, an electrician can help locate electrical issues. 

If you encounter a burning odor, shut off the main power and call for emergency service from an electrician. 

The electrical wires burn because power surges through the circuit, melting the wire insulation.

What is Nuisance Tripping

Nuisance tripping is when a breaker trips without a fault to warrant the interruption to the electric current flow.

Nuisance tripping occurs due to several reasons:

Stringent Protection on Circuits 

Sometimes the circuit is protected by stringent conditions that detect any variance as a fault and cause a trip. 

Such stringent conditions can be tuned to accommodate the home’s or building’s electric needs.

A Highly Sensitive Circuit Breaker

In some cases, the circuit breaker has been set to susceptible settings so that they can detect even the slightest fault, even a minor average variance.

For example, the manufacturer can set an AFCI circuit breaker to sensitive standards to detect another circuit’s arc. This common issue may occur in a daisy chain where the circuit breakers connect in a linear series. There may be a faulty electrical outlet you are unaware of on the circuit. It is common for multiple rooms to share a breaker in older houses.

The Breaker Encounters Power Under Different Conditions

The variation in the current is normal, but the breaker responds to it by tripping because the flow is outside the breaker’s regular operation.

Your circuit breaker is tripping because the voltage it is encountering is not within the standard operation. You will need to adjust the circuit breaker or the voltage to eliminate nuisance tripping.

The Breaker Trips with Nothing Plugged in

A breaker tripping with nothing plugged in occurs when a hot, neutral wire is touching somewhere in the circuit. The common causes include frayed or damaged electrical wires, loose connections, faulty electrical receptacles, light switches , or dimmers.

Electrical wire damage happens when:

  • wiring is chewed by animals such as rats, squirrels , raccoons, etc
  • wire sheathing and insulation ages and become frayed
  • wires rub against sharp edges such as punch-outs with missing grommets or wire clamps

Loose connections often occur when electrical wire nuts come loose or electrical tape wears out causing wires to touch.

Defective wiring can be anywhere along the circuit, so it’s best to contact a licensed electrician to troubleshoot why the breaker is tripping.

Replacing a Bad Circuit Breaker

  • Check the electrical panel to see the compatible approved circuit breaker brands. Also, make a note of the brand of the electric panel . This is to help you determine if there are upgrades they could recommend for the hardware.
  • Order online or go to the hardware store and purchase the breaker of the same voltage as the one you are replacing.
  • Go and open the electrical box and switch off the bad breaker. Loosen the terminals and remove the wires using a pair of needle-nosed pliers. Ensure the pliers have rubber insulated handles to avoid shock or electrocution since you will use the pliers to grab the live wires from the terminal. That is a safety measure.
  • Remove the bad breaker. Replace it with the new breaker and slip its clips into place. Remember to switch off the replacement breaker.
  • Next, using the pliers, hold the wiring and tighten the screws on the terminal. It is crucial to ensure that the wires and screws in the terminals are in the right place.
  • Turn the breaker on and replace the electrical panel cover.

Can a Breaker Fail Without Tipping

If you have a newer electrical panel , it’s not likely for a breaker to fail and not trip. However, in older breaker boxes like Federal Pacific , the breaker failing to trip is common.

The main reason Federal Pacific was investigated by the Consumer Products Safety Commission (CPSC) was widespread structure fires involving breakers failing to trip when an electrical overload was present. They found that the circuit breaker contacts would fuse to the bus bar.

Modern breakers will trip when a failure occurs as an added layer of safety. Most older breakers did not have these safeguards.

With AFCI breakers, if the Internal sensing mechanism fails, the breaker reverts to a standard breaker. The AFCI sensor mechanism will no longer work, but the breaker would still trip from overcurrent protection. Therefore, you should test the AFCI breaker regularly.

Conclusion 

Listen to your circuit breaker . It’s alerting you of a problem when it trips. That communication could be a problem with the breaker itself, the circuit, or the amount of electric current coming into your home.

MicroLogic ™ Electronic Trip Systems

Overview of micrologic trip systems, p trip unit with power metering.

circuit breaker trip alarm

All MasterPact circuit breakers are equipped with the MicroLogic trip system to protect power circuits and loads. MicroLogic trip systems use a set of current transformers (called CTs or sensors) to sense current, a trip unit to evaluate the current, and a tripping solenoid to trip the circuit breaker. Adjustable rotary switches on the trip unit allow the user to set the proper overcurrent or equipment ground-fault current protection required in the electrical system. If current exceeds a set value for longer than its set time delay, the trip system opens the circuit breaker. Alarms may be programmed for remote indications. Measurements of current, voltage, frequency, power, and power quality optimize continuity of service and energy management. MicroLogic trip units can be changed on-site.

Integration of protection functions in the Application Specific Integrated Circuit (ASIC) electronic component used in all MicroLogic trip units guarantees a high degree of reliability and immunity to conducted or radiated disturbances. On MicroLogic P and H trip units, advanced functions are managed by an independent microprocessor.

MasterPact circuit breakers are shipped with the long-time pickup switch set at 1.0 and all other trip unit adjustments set at their lowest settings. Actual settings required for a specific application must be determined by a qualified consultant or plant engineer. A coordination study is recommended to provide coordination between all circuit breakers in the distribution system.

The thermal imaging function protects the cables or bus bars from overheating in case of low amplitude repetitive faults. Such overheating can be due to repetitive motor starting, fluctuating load, intermittent ground faults, or subsequent closing after a fault.

Traditional electronic protection does not protect against repetitive faults because the duration of each overload above the pickup setting is too short to achieve effective tripping. Nevertheless, each overload involves a temperature rise in the installation, the cumulative effect of which could lead to overheating of the system.

The thermal imaging function remembers and integrates the thermal heating caused by each pickup setting overrun. Before tripping, the integrated heating value will reduce the associated time delay and, therefore, the reaction of the trip unit will be closer to the real heating of the power network system.

After tripping, the function will also reduce the time delay when closing the circuit breaker on an overload.

Power Supply Information

Provides fault protection for LSIG functions.

Provides LED trip indication (powered by an onboard battery).

All display functions and trip unit features power-up with current flow on one phase greater than or equal to the values in the table to the left.

Ground-fault push-to-trip button works for testing ground fault with current flow on one phase greater than or equal to the values shown in the following table.

The Ammeter (A) trip unit provides all of the above plus additional functionality when powered by external 24 Vdc power supply:

Ammeter and bar graph displays are functional with or without current flowing through the circuit breaker.

Trip settings and (Max) current readings can be accessed on the display by pressing navigation button with or without current flowing through the circuit breaker.

The ground-fault push-to-trip button works for testing ground fault with or without current flowing through the circuit breaker.

Optional Modbus™ communications—also requires a separate 24 Vdc power supply for the circuit breaker communications module.

The P and H trip units were designed to be used with the external 24 Vdc power supply. The large LCD display requires too much current to be powered by current flow through the circuit breaker. The P and H trip units do have a voltage power supply which will power the trip unit with 100 Vac or more between two phases or phase to neutral. The standard configuration for the voltage probes inside the circuit breaker is at the bottom connections. If the circuit breaker was open in a top fed application, there would be no voltage at the bottom of the circuit breaker and the trip unit would not be powered.

Provides all of the above.

LCD display and backlight are functional.

Ground-fault push-to-trip button works for testing ground fault.

All metering, monitoring, and history logs are functional.

Communications from trip unit to M2C and M6C programmable contact modules are powered by a 24 Vdc supply at F1 and F2. M6C also requires a 24 Vdc external power supply.

Modbus communications—also requires a separate 24 Vdc power supply for the circuit breaker communications module.

MicroLogic Trip Units — Overview

The sensing system responds to the flow of current through the circuit breaker. Electronic trip circuit breakers are limited to ac systems because the electronic trip system uses current transformers to sense the current. The MicroLogic trip unit samples the current waveform to provide true RMS protection through the 15th harmonic.

This true RMS sensing gives accurate values for the magnitude of a non-sinusoidal waveform. Therefore, the heating effects of harmonically distorted waveforms are accurately evaluated.

The MicroLogic H trip unit provides additional sampling of the waveforms to measure and provide waveform capture of harmonic distortion to the 31st harmonic.

MasterPact universal power circuit breakers use MicroLogic electronic trip systems to sense overcurrents and trip the circuit breaker. The MicroLogic basic trip unit is standard and all MasterPact circuit breakers can be equipped with the optional MicroLogic trip systems listed below:

MicroLogic 6.0A Trip Unit

MicroLogic A trip units measure the true RMS value of currents. They provide continuous current measurement from 0.2 to 20 x I n with an accuracy of 1.5% (including sensors). No auxiliary source is needed where I > 0.2 x I n . The optional external power supply (24 Vdc) makes it possible to display currents where I < 0.2 x I n and to store values of the interrupted current. A digital LCD screen continuously displays the most heavily loaded phase (Imax) or displays the Ia, Ib, Ic, Ig, and (on four-pole circuit breakers only) In stored current and setting values by successively pressing the navigation button.

Four wire Modbus, RTU, RS485 or two wire Modbus, TRU, RS485 plus ULP. See Additional Wiring Information for MasterPact NW NT Circuit Breakers .

In conjunction with an optional communication network, the trip unit transmits the following parameters:

MicroLogic 6.0A Trip Unit Ground-Fault Settings

Micrologic 5.0p and 6.0p trip units with power metering.

The adjustable protection functions of the 5.0P and 6.0P trip units are identical to those of MicroLogic A trip unit (overloads, short circuits, equipment ground-fault protection); see MicroLogic 2.0A, 3.0A, 5.0A and 6.0A Trip Units with Ammeter .

These units also feature:

Fine adjustment : Within the range below the rotary switch setting, fine adjustments of pickups/delays in steps of 1 A/s (except for short-time and ground-fault) are possible on the keypad or remotely by the communication network.

Inverse definite minimum time lag (IDMTL) setting : Coordination with fuse-type or medium-voltage protection systems is optimized by adjusting the long-time delay curve around 6 x I r axis. This setting ensures better coordination with certain loads.

Neutral protection : On three-pole circuit breakers, neutral protection may be set using the keypad or remotely using the communication network to one of four positions:

— 1/2N (1/2 x I n )

— 1N (1 x I n )

— 2N (2 x I n )

MicroLogic 6.0P Trip Unit

When the cover is closed, the keypad may no longer be used to change the protection settings, but it still provides access to the displays for measurements, histories, indicators, etc. Depending on the thresholds and time delays set, the MicroLogic P trip unit monitors current, voltage, power, frequency, and phase sequence. Each threshold overrun may be signalled remotely via the communication network.

Each threshold overrun may be combined with tripping (protection) or an indication carried out by an optional M2C/M6C programmable contact (alarm), or both (protection and alarm).

The maintenance record can be consulted using the full-function test kit or remotely via the communication network. It can be used as an aid in troubleshooting and to assist scheduling for device maintenance operations.

Recorded indications include:

Highest current measured

Operation counter (both cumulative total and total since last reset)

Number of test kit connections

Number of trips in operating mode

Contact wear (MasterPact NW only)

Load shedding and reconnection parameters can be set according to the power or the current flowing through the circuit breaker. Load shedding is carried out by a remote computer via the communication network or by an M2C or M6C programmable contact.

The M2C (two contacts) and M6C (six contacts) programmable contacts may be used to signal threshold overruns or status changes. They can be programmed using the keypad on the MicroLogic P and H trip units or remotely using the communication network. These contacts are required to obtain data from the protective relay functions on Type P and Type H trip units.

MicroLogic 5.0P and 6.0P Trip Unit Settings

Micrologic 6.0p trip unit ground-fault setting, settings for alarms for other protection functions for micrologic 5.0p and 6.0p trip units, load-shedding settings for current and power metering for micrologic 5.0p and 6.0p trip units.

The last ten trips and ten alarms are recorded in two separate history files that can be displayed on the screen (sample displays are shown to the right). The following information is contained in these files:

The MicroLogic P trip unit calculates in real time all electrical values V, A, W, VAR, VA, Wh, VARh, VAh, Hz, power factor, and crest factor. The MicroLogic P trip unit also calculates demand current and demand power over an adjustable time period.

Real-Time Metering: The value displayed on the screen is refreshed every second. Minimum and maximum measurement values are stored in memory.

Demand Metering: The demand is calculated over a fixed or sliding time window that can be programmed from five to sixty minutes. Depending on the contract signed with the power supplier, specific programming makes it possible to avoid or minimize the cost of overrunning the subscribed power. Maximum demand values are systematically stored and time stamped.

Four wire Modbus, RTU, RS485—The communication network may be used to:

Remotely read parameters for the protection functions.

Transmit all the measurements and calculated values.

Signal the causes of tripping and alarms.

Consult the history files and the maintenance indicator record.

In addition, an event log of the last 100 events and a maintenance record, which is stored in the trip unit memory but not available locally, may be accessed via the communication network.

The Modbus communication system is compatible with Powerlogic™ System Manager™ (SMS) software.

The event log may be accessed by a remote computer via the communication network. All events are time stamped and include:

Beginning and end of alarms

Modifications to settings and parameters

Loss of time

Overrun of wear indicators

Test kit connections

Counter resets

System faults (thermal self-protection, major fault and minor fault alarms)

MicroLogic 5.0H and 6.0H Trip Units with Harmonic Metering

In addition to the P functions, the MicroLogic H trip units offer:

In-depth analysis of power quality including calculation of harmonics and the fundamentals.

Diagnostics aid and event analysis through waveform capture.

Customized alarm programming to analyze and track down a disturbance on the ac power system.

Systematic time stamping of all events and creation of logs.

The MicroLogic H trip unit offers all the measurements carried out by the MicroLogic P trip unit, with the addition of phase-by-phase measurements of power and energy as well as calculation of:

Current and voltage total harmonic distortion (THD, thd).

Current, voltage and power fundamentals (50/60 Hz).

Harmonic components (amplitude and phase) up to the 31st current and voltage harmonic.

Real-Time Metering : The value displayed on the screen is refreshed every second. The table below shows what is measured in real-time metering.

Demand Metering : Similar to the MicroLogic P trip unit, demand values are calculated over a fixed or sliding time window that can be set from five to 60 minutes.

MicroLogic H trip units can capture and store current and voltage waveforms using digital sampling techniques similar to those used in oscilloscopes. Using the information available in the captured waveform, it is possible to determine the level of harmonics as well as the direction and amplitude of the flow of harmonic power.

Users of MicroLogic H trip units can record manually via the keypad the following waveforms:

The four currents: I a , I b , I c , and I N

The three phase-to-phase voltages: V ab , V bc , and V ca

Waveforms may be displayed on the graphic screen of MicroLogic H trip units or communicated over a networked system. The recording takes place over one cycle with a measurement range of 0 to 1.5 I N for current and 0 to 690 volts for voltage. The resolution is sixty-four points per cycle.

The instantaneous value of each measurement can be compared to user-set high and low thresholds. Overrun of a threshold generates an alarm. Programmable action can be linked to each alarm, including circuit breaker opening, activation of an M2C or M6C contact, recording of measurements in a log, etc.

Each event is recorded with:

The date, time, and name of the event.

The event characteristics.

Setting the display language: System messages can be displayed in six different languages:

English - US

English - UK

The desired language is selected via the keypad.

Protection functions: All current-based protection functions require no auxiliary source. Voltage-based protection functions are connected to ac power via a voltage measurement input built into the circuit breaker on the bottom side. (Optional external voltage measurement is available.)

Accuracy of measurements (including sensors):

Voltage (V) 1%

Current (A) 1.5% (higher accuracy [1%] may be achieved with special calibration on the current transformer [CT characterization option])

Frequency (Hz) 0.1 Hz

Power (W) and energy (Wh) 2.5%

The MicroLogic H trip unit uses a dedicated metering data chain separate from the protection data chain so that a greater number of data samples can be used for metering. This increases the number of samples taken per time period, which in turn gives the H trip unit a higher degree of metering accuracy.

Stored information: The fine setting adjustments, the last 100 events and the maintenance record remain in the trip unit memory even when power is lost.

Reset: An individual reset, via the keypad or remotely, will reset alarms, minimum and maximum data, peak values, counters and the indicators.

MicroLogic Trip Unit Functions

circuit breaker trip alarm

The long-time pickup switch sets the maximum current level the circuit breaker will carry continuously. The maximum current level (I r ) is the long-time pickup setting multiplied by the sensor plug amperage (I n ). If the current exceeds this value for longer than the long-time delay time, the circuit breaker will trip.

The long-time delay switch sets the length of time that the circuit breaker will carry a sustained overload before tripping. Delay bands are labeled in seconds of overcurrent at six times the ampere rating. For maximum coordination, there are eight delay bands. Long-time delay is an “inverse time” characteristic in that the delay time decreases as the current increases.

The trip unit includes an alarm indicator  that will be lit continuously when the current is above 100% of the pickup setting.

Short-Time and Instantaneous Trip Functions

circuit breaker trip alarm

The short-time pickup switch sets the short-circuit current level at which the circuit breaker will trip after the set short-time delay. The short-time current (I sd ) equals the short-time pickup setting multiplied by the long-time pickup (I r ).

The short-time delay switch sets the length of time the circuit breaker will carry a short circuit within the short-time pickup range. The delay (based on 10 times the ampere rating I r ) can be adjusted to four positions of I 2 t ramp operation (I 2 t ON) or five positions of fixed time delays (I 2 t OFF). I 2 t ON delay is an “inverse time” characteristic in that the delay time decreases as the current increases. Short-time delay for the 2.0 trip unit is fixed at a delay band of 20 to 80 ms.

The instantaneous pickup switch sets the short-circuit current level at which the circuit breaker will trip with no intentional time delay. The instantaneous current (I i ) is equal to the instantaneous pickup setting multiplied by the sensor plug amperage (I n ).

The instantaneous function will override the short-time function if the instantaneous pickup is adjusted at the same or lower setting than the short-time pickup. In trip units with both adjustable short-time and instantaneous trip functions, the adjustable instantaneous trip can be disabled by setting Instantaneous pickup to OFF.

circuit breaker trip alarm

The ground-fault pickup switch sets the current level at which the circuit breaker will trip after the set ground-fault delay. Ground-fault pickup values (I g ) are based on circuit breaker sensor plug (I n ) only, not on the rating plug multiplier (I r ). Changing the rating plug multiplier has no effect on ground-fault pickup values.

The ground-fault delay switch sets the length of time the circuit breaker will carry ground-fault current which exceeds the ground-fault pickup level before tripping. The delay (based on the sensor plug amperage (I n ) can be adjusted to four positions of I 2 t ramp operation (I 2 t ON) or five positions of fixed time delays (I 2 t OFF). I 2 t ON delay is an “inverse time” characteristic in that the delay time decreases as the current increases.

Enerlin'X Communication Wiring System

The wiring system is designed for low-voltage power switchboards. Installation does not require special tools or training. The prefabricated wiring ensures both data transmission (Modbus protocol) and 24 Vdc power distribution for the communications modules on the MicroLogic trip units.

circuit breaker trip alarm

The MasterPact can be integrated into Ethernet and Modbus communication environments.

There are four possible functional levels that can be combined.

The Modbus RS 485 (RTU protocol) system is an open bus on which communicating Modbus devices (MasterPact NW with Modbus COM, Power Meter PM700, PM800, PowerPact P/Rframe, etc.) are installed. All types of PLCs and microcomputers may be connected to the bus.

The Modbus communication parameters (address, baud rate, parity) are entered using the keypad on the MicroLogic A, P, or H trip unit. For a switch, it is necessary to use the Electrical Asset Manager or RSU (Remote Setting Utility) MicroLogic utility.

Number of Devices

The maximum number of devices that may be connected to the Modbus bus depends on the type of device (ComPact circuit breaker with Modbus COM, PM700, PM800, MasterPact circuit breaker, etc.), the baud rate (19200 is recommended), the volume of data exchanged and the desired response time. The RS 485 physical layer offers up to thirty-two connection points on the bus (one master, thirty-one slaves).

Length of Bus

The maximum recommended length for the Modbus bus is 3940 feet (1200 meters).

Bus Power Source

A 24 Vdc power supply is required (less than 20% ripple, insulation class II).

Ethernet is a data link and physical layer protocol defined by IEEE 802 10 and 100 Mbps specifications that connects computer or other Ethernet devices. Ethernet is an asynchronous Carrier Sense Multiple Access with Collision detection (referred as CSMA/CD) protocol. Carrier Sense means that the hosts can detect whether the medium (coaxial cable) is idle or busy.

Multiple Access means that multiple hosts can be connected to the common medium. Collision Detection means a host detects whether its transmission has collided with the transmission of another host (or hosts).

IFE Ethernet interface can be connected to a PC or a laptop over Ethernet. The maximum length of Ethernet cable is 325 feet (100 meters). IFE Ethernet interface + gateway provides a Modbus TCP/IP gateway over Ethernet to enable Modbus TCP communication from a Modbus TCP master to any Modbus slave devices connected to it. The maximum active Modbus TCP client connection is twelve.

IFE Ethernet interface has an embedded web server (web page).

All Masterpact devices can be fitted with the communication function thanks to the COM option. Masterpact uses the Ethernet or Modbus communications protocol for full compatibility with the supervision management systems.

For fixed and drawout devices, the common communication option is made up of:

BCM ULP Module

circuit breaker trip alarm

A BCM ULP module, installed behind the MicroLogic trip unit and supplied with a set of switches (OF, SDE, PF and CH switches), a kit for connection to shunt close (XF) and shunt trip (MX1) communicating voltage releases, and a COM terminal block (inputs E1 to E6). This module is independent of the trip unit and receives and transmits information on the communication network. An infra-red link transmits data between the trip unit and the communication module. (Consumption: 30 mA, 24 V)

The IFM module, the Modbus interface for connection to the network, contains the Modbus address (1 to 99) declared by the user using the two dials in front. It automatically adapts (baud rate, parity) to the Modbus network in which it is installed.

The IFE module, the Ethernet interface for low-voltage circuit breakers, enables an intelligent modular unit (IMU) such as a Masterpact NT/NW or PowerPact circuit breaker to be connected to an Ethernet network. Each circuit breaker has its own IFE and a corresponding IP address.

For drawout devices the Cradle Management option must be added:

IO Application Module

circuit breaker trip alarm

The IO (Input/Output) application module for low-voltage circuit breakers is delivered with the drawout devices ordered with the COM option for cradle management. It must be installed on a steel DIN rail that is properly grounded near the device. The IO module must be connected to the ULP system and to the cradle position contacts (CD, CT, CE) that transmit the position of the circuit breaker in the cradle.

For communicating remote control, shunt close (XF) and shunt trip (MX1) communicating voltage releases must be added:

The shunt close (XF) and shunt trip (MX1) communicating voltage releases are equipped for connection to the communication module.

The remote-tripping function shunt trip (MX2) and undervoltage release (MN) are independent of the communication option. They are not equipped for connection to the communication module.

circuit breaker trip alarm

The IFE interface and IFE interface + gateway are DIN rail mounted devices. A stacking accessory enables the user to connect several IFMs (ULP to Modbus interfaces) to an IFE interface + gateway without additional wiring.

The IFE interface and the IFE interface + gateway must always be supplied with 24 Vdc.

The IFMs stacked to an IFE interface + gateway have power supplied by the IFE interface + gateway, thus it is not necessary to supply them separately. It is recommended to use a UL listed and recognized limited voltage/limited current or a class 2 power supply with a 24 Vdc, 3 A maximum.

The connection to an IFE interface or IFE interface + gateway requires a communication module embedded into the circuit breaker:

MasterPact NT/NW (fixed or drawout) circuit breakers: BCM ULP communication module

Drawout MasterPact NT/NW circuit breakers: BCM ULP and its respective IO (Input/Output) application module.

All connection configurations for MasterPact NT/NW circuit breakers require the circuit breaker ULP cord. The insulated NSX cord is mandatory for system voltages greater than 480 Vac. When the second ULP RJ45 connector is not used, it must be closed with a ULP terminator (TRV00880).

Network Communication Interface

Ifm modbus communication interface.

IFM Modbus Communication Interface. Ref.: TRV00210

circuit breaker trip alarm

An IFM Modbus communication interface is required for connection of a MasterPact or PowerPact circuit breaker to a Modbus network as long as this circuit breaker is provided with a ULP (Universal Logic Plug) port. The port is available on the BCM ULP.

Once connected, the circuit breaker is considered as a slave by the Modbus master. Its electrical values, alarm status, open/close signals can be monitored or controlled by a Programmable Logic Controller or any other system.

Two RJ45 sockets, internal parallel wiring.

Connection of a single circuit breaker.

A ULP line terminator or an FDM121 display unit must be connected to the second RJ45 ULP socket.

The RJ45 sockets deliver a 24 Vdc supply fed from the Modbus socket.

Built-in test function, for checking the correct connection to the circuit breaker and FDM121 display unit.

Modbus Slave Port

Top socket for screw-clamp connector, providing terminals for:

— 24 Vdc input supply (0 V, +24 V)

— Modbus line (D1, D2, Gnd) 2-wire Modbus system

Lateral socket, for DIN-rail stackable connector. Both top and lateral sockets are internally parallel wired.

Multiple IFMs can be stacked, thus sharing a common power supply and Modbus line without individual wiring.

On the front face:

— Modbus address setting (1 to 99): two coded rotary switches

— Modbus locking pad: enables or disable the circuit breaker remote control and modification of IFM parameters

Self-adjusting communication format (Baud rate, parity).

Stacking an IFM

The IO (Input/Output) application module for an low-voltage circuit breaker is part of an ULP system with built-in functions and applications to enhance the application needs. The ULP system architecture can be built without any restrictions using the wide range of circuit breakers.

No additional setting with the customer engineering tool required.

The resources not assigned to the pre-defined application are free for additional user-defined applications:

cradle management

circuit breaker operation

cradle management + ERMS (Energy Reduction Maintenance Setting)

light and load control

User-defined applications are processed by the IO application module in addition to the pre-defined application selected.

The user-defined applications are available depending on:

the pre-defined application selected

the IO application module resources (inputs and outputs) not used by the application

The resources required by user-defined applications are assigned using the customer engineering tool:

energy management

The IO application module is a DIN rail mounted device. Install on a steel DIN rail that is properly grounded near the device.

The application rotary switch enables the selection of the pre-defined application. It has nine positions and each position is assigned to a pre-defined application. The factory set position of the switch is pre-defined application one.

The setting locking pad on the front panel of the IO application module enables the setting of the IO application module by the customer engineering tool.

Q: Every few hours—sometimes minutes!—my living room and one side of my kitchen lose electrical power. I’ll check the breaker panel and, sure enough, a circuit breaker has tripped…again. Should I call an electrician, or is there a simple DIY fix I can try first?

A: While it’s frustrating when a circuit breaker keeps tripping, they are important safety mechanisms. Designed to shut off the electrical current when something goes wrong, circuit breakers are one of the best ways of protecting a home from an electrical fire. “When a circuit breaker trips, typically it is because we use too much electricity, which causes it to overload and turn off,” says Christopher Haas, expert electrician and owner of Haas & Sons Electric in Millersville, Maryland. For those who need an electrical panels 101 refresher course or aren’t sure how to reset circuit breakers, each breaker has an on/off switch and controls a separate electrical circuit in the home. When a breaker trips, its switch automatically flips “off,” and it must be manually turned back on to restore electricity to the circuit. For those wondering, “Is it dangerous if a circuit breaker keeps tripping?” the answer is that it can be, depending on the source of the problem. An electrician can ultimately deal with the root issue, but a little sleuthing will reveal whether it’s something that’s easily remedied.

In many cases, the cause of a circuit breaking tripping is an overloaded circuit.

A circuit overloads when more electrical current is being drawn through the wires than they can handle, tripping the circuit breaker. If this happens, there may be a few additional signs:

  • Buzzing noises coming from outlets
  • Devices charging slowly
  • Electrical outlets not working
  • Flickering lights
  • Scorch marks on outlets and light switches

If a circuit breaker keeps tripping in one room, homeowners can test for circuit overload by turning off all the switches in the affected area and unplugging all appliances and devices. After the breaker is flipped back on, the devices can be turned back on one at a time, with homeowners waiting a few minutes in between to see if the circuit remains on. If the breaker trips before all the appliances are turned on, the experiment can be repeated, this time turning them on in a different order. It may be necessary to do this several times to find out how many appliances can be operated at once before the circuit overloads.

“As a short-term solution, you can unplug unnecessary appliances to prevent tripping circuit breakers. You may still get some trips, but you can limit them by unplugging devices that you don’t need to use,” advises Dan Mock, vice president of operations at Mister Sparky , an electrical company with 90 locations in the U.S. The best long-term solution, however, is to pay an electrician for the cost to rewire the house and add additional circuits. The cost to replace an electrical panel is about $1,274 on average.

Other times, the issue may be caused by a short circuit.

A “short” circuit means that two wires that should not be coming into contact are inadvertently touching, triggering a sudden surge of electricity through the wires. A short can occur in an outlet, a switch, or within an appliance if wires are loose or have been chewed through by mice or pets. Some signs of a short circuit include:

  • Popping sounds
  • Discolored outlets or switches
  • Burning smells

Testing to see if an appliance has a short is similar to testing for an overloaded circuit. When an appliance that has a short in its wiring is turned on, it will immediately trip the circuit. Homeowners can also try plugging it into an outlet in a different room. If the breaker for that room trips, there’s a short in the appliance (if it’s unclear what breaker goes to what room, the breaker can be identified with one of the best circuit breaker finders ). Electrical shorts can be a major fire hazard, so it’s a good idea to call a licensed electrician for this circuit breaker repair. It’s wise to stop using the outlet or appliance until a pro takes care of the problem.

A close up of a circuit breaker.

Another potential cause of a circuit breaker tripping is a ground fault.

A ground fault occurs when the electricity running through a home’s wiring diverts from the wiring loop and travels to the ground, usually due to faulty wiring or water infiltration in an outlet or switch box. Water is a conductor, which is why walking through puddles is often listed as something not to do in a power outage in case of downed power lines. Once water makes contact with wires, electricity can jump from the wiring loop and follow the water trail. This creates a surge in electricity leading to a tripped circuit breaker. If a person comes in contact with the electricity that is on its way to the ground, this can result in electrocution. Homeowners may notice a few signs of a ground fault, including:

  • Tripped GFCI (ground fault circuit interrupter) outlets;
  • A burning smell coming from an outlet; and
  • Lights flickering.

Newer electrical breakers have features designed to protect against the danger of ground faults. According to Haas, “Ground fault breakers sense electricity going to earth as opposed to going through the wires of the circuit. You’ll find [these] for bathrooms, kitchens, garages, exteriors, and basements.” GFCI outlets are another safety feature that shut off the electric current within a fraction of a second of sensing a ground fault.

If a ground fault is the problem, the cause of the errant water must be discovered and repaired, and any damaged wiring must also be replaced. It’s also a good idea to install GFCI outlets in rooms where water is commonly used. A GFCI outlet costs $210 on average.

Sometimes a bad or worn-out circuit breaker can be the culprit.

In some cases, the circuit breaker itself may be faulty. Breakers that are old, damaged, or were installed incorrectly may trip frequently for no apparent reason. Alternatively, faulty breakers may not trip when they are supposed to, leaving the home at risk of electrical fire. Some signs of a bad circuit breaker include:

  • The circuit breaker getting hot and tripping frequently;
  • The circuit breaker won’t reset;
  • It has been over 10 years since the breaker was last serviced; and
  • The breaker has scorch marks.

An important electrical safety tip to keep in mind is that resetting a breaker over and over again can cause what is called an arc flash, which is a small electrical explosion that can be deadly. If resetting the breaker once does not remedy the issue, it’s a good idea for the homeowner to hire an electrician near them who knows how to replace a circuit breaker safely. Mock warns, “Don’t take any chances with circuit breakers. Instead, call a licensed electrician who knows the safe ways to replace breaker boxes, upgrade circuits, and diagnose potential electrical problems in your home.” Wiring a breaker box is a job to leave to an experienced electrician.

A professional electrician can help determine the specific cause of a frequently tripping circuit breaker.

Most circuit breaker problems—aside from those explained in the sections above—will need to be inspected and addressed by a licensed electrician. According to the Electrical Safety Foundation International (ESFI) , each year “thousands of people in the United States are critically injured and electrocuted as a result of electrical fires, accidents, [or] electrocution in their own homes.” While homeowners may be tempted to save on electrician costs by attempting circuit breaker replacement or repair themselves, electrical work is not suitable for casual DIYers. “Yes, you have to pay, but you can save many hours of head-scratching by hiring an electrician. Electricians will also have all the right tools for diagnosing and repairing the circuit,” Haas adds. “Lastly, they will come with a warranty/guarantee should something arise, and they will typically return at no additional cost.”

Circuit Breaker Accessories Explained

circuit-breaker-accessories-explained-cover

The purpose of accessories on a power circuit breaker is to provide additional functions and protection beyond basic circuit interruption. For example, a motor can automatically charge the closing spring of the breaker, reducing the time required for the breaker to close.

Other accessories can offer additional functions, such as undervoltage or overvoltage protection, or enable remote operation of the breaker. These accessories enhance the safety, reliability, and functionality of the power distribution system.

Circuit breaker accessories are matched to the system control voltage and may be available as factory-installed options or in field-installable kit form. Some typical control voltages include: 250VDC, 240VAC, 120VAC, 125VDC, 48VDC, 24VDC.

Auxiliary Switch

Auxiliary Switches provide remote indication of the breaker main contact position, changing state when the minimum isolating distance between the main contacts is reached. They typically feature Form C contacts, with options for both NO (Normally Open) and NC (Normally Closed) states, sharing a common neutral.

A Contact – Open or closed same as the breaker.

B Contact – Opposite to the breaker contacts.

Connected/Closed Switches

Connected/closed switches combine information from the “connected device” and “closed device,” indicating that the “circuit is closed.”

Bell Alarm / Overcurrent Trip Switch

The overcurrent trip switch provides remote indication that the circuit breaker has opened due to an electrical fault. Typically equipped with one set of Form C contacts, offering options for both NO (Normally Open) and NC (Normally Closed) states with a common neutral. The switch is activated, and the outputs change state whenever the breaker is tripped by an overcurrent, ground fault, or protective relay function via the Trip Unit.

Circuit Breaker Bell Alarm / Overcurrent Trip Switch

A trip caused by the manual OPEN button or by the Shunt Trip or Undervoltage Trip Device accessory does not activate the Bell Alarm. The accessory can be reset, returning the contacts to their normal configuration, by reclosing the breaker or by manually resetting the target on the breaker escutcheon.

Bell Alarm Lockout

The Bell Alarm with Lockout prevents closing of the breaker after a protection trip until the lockout is reset.

Electric Reset

The electric reset is used to reset the circuit breaker remotely after an electrical fault.

Ready-to-close Switch

The ready-to-close switch indicates that the following conditions are met and the circuit breaker can be closed:

  • The circuit breaker is open
  • The closing springs are charged
  • The circuit breaker in not locked/interlocked in open position
  • There is no standing closing order
  • There is no standing opening order

Secondary disconnects connect the circuit breaker to the control circuits.

Spring-Charging Motor

The spring-charging motor provides a means of electrically charging the closing springs automatically after the circuit breaker closes. When the springs are fully charged, a cutoff switch automatically de-energizes the motor. The closing springs will recharge automatically after the breaker closes unless an external switch contact is wired into the spring-charging circuit.

Spring-Charged Contact

The spring-charged contact indicates that the circuit breaker is charged. Usually a form C contact.

Shunt Trip / Shunt Close

The shunt trip coil opens the circuit breaker when energized. Shunt Close will close a circuit breaker when energized if the device is ready to close. Shunt trip and shunt close share the same coil; the action is determined by the location of the coil. The shunt close accessory features an anti-pump feature that prevents the breaker from repeatedly closing if the closing signal is maintained.

Circuit Breaker Shunt Trip / Shunt Close Accessory

Undervoltage Trip

The undervoltage trip opens the circuit breaker when its supply voltage drops below the threshold voltage. Undervoltage trip coils require continuous power supply to keep the circuit breaker closed.

Circuit Breaker Undervoltage Trip Accessory

Time-Delay Module for Undervoltage Trip

The time-delay module for the undervoltage trip can be used to set an adjustable time delay before the undervoltage trip opens the circuit breaker, preventing nuisance tripping from a momentary voltage drop. The time-delay mechanism is connected in series with the undervoltage trip (MN) and is installed outside of the circuit breaker.

Circuit Breaker Undervoltage Time Delay Module

Electric Lockout

The electric lockout accessory uses a coil similar to an Undervoltage Trip Device to prevent the breaker from closing unless the coil is energized. Consequently, the breaker cannot be closed unless control voltage is applied; however, the loss of control voltage will not trip the breaker.

For instance, two breakers can be interlocked to ensure that they cannot both be closed simultaneously. The Electric Lockout coils on the two breakers to be interlocked can be wired in series with a normally closed Auxiliary Switch contact on the other breaker to provide the interlocking function. Mechanical bypass is utilized to permit cold startup when control power is not available.

Electrical Closing Push Button

The electrical closing push button closes the circuit breaker electrically via the shunt close. Requires installation of shunt close.

Operations Counter

The operations counter registers the total number of operating cycles for the circuit breaker.

Communications Module

The circuit breaker communications module provides communication between circuit breaker trip unit and the communication network. Dedicated switches can be used to read status of circuit breaker. Actuators can be used to control the circuit breaker.

Position Switch

The cell position switch indicates the circuit breaker position in the cradle/cell. This accessory is for drawout circuit breakers only and typically contains normally-open and normally-closed contacts. There can be one to three position switches for each type.

  • Disconnected

Open-Fuse Lockout

The Open-Fuse lockout is provided on integrally fused breakers or when the breaker is used in combination with a Fuse Rollout Element. When any fuse blows, the Open-Fuse Lockout trips the breaker to prevent single-phasing.

An indicator shows which fuse has blown. The breaker is mechanically trip-free and cannot be reclosed until the blown fuse is replaced, and the Open-Fuse Lockout is reset.

Hidden-Close Button

The Hidden Close Button is an unmarked replacement for the normal CLOSE button. Pressing the Hidden Close Button in the usual manner will not close the breaker; instead, a rod inserted with light pressure is used to engage the hidden-close button.

Why Is the Circuit Breaker Tripping? Troubleshooting Tips for your Breaker Box

If you've ever turned on your microwave and caused a power outage in your kitchen, it is likely that your circuit breaker tripped.

A circuit breaker might trip for several different reasons. In some cases, the breaker box simply needs replacing. But most of the time, a circuit breaker cuts off power for one of three reasons:

Short Circuit

Ground fault.

Once you understand the type of circuit breaker you have and the potential causes for a trip, you can work through our troubleshooting tips.

What are the different types of circuit breakers?

The three main types of circuit breaker voltages are low, medium, and high. Low voltage circuit breakers mostly operate in domestic and commercial environments. Medium and high voltage electrical circuits are better for large, industrial applications.

Different circuit breakers have different fault interrupters, or mediums that trigger the breaker to cut power. Depending on the voltage, the way the circuit interrupts the flow of electricity varies. The most common types of breakers you will encounter in homes and businesses are low voltage circuits, such as:

  • Magnetic: Uses an electromagnet to cut off power when the electrical current gets too strong
  • Thermal: Equipped with metal strips that bend and cut off the power when they get too hot
  • Thermal-magnetic: Combines the interrupting functions of both thermal and magnetic circuit breakers
  • GFCI: Features a “test” button along with an “on” and “off” switch that protects your home against ground faults

Circuit Overload

Circuit Breaker

The first reason your circuit breaker could trip is if there are too many devices running on the circuit. The electrical load capacity is the maximum limit a circuit can hold.

All breakers have an amperage rating, typically 15-amp or 20-amp. Most circuit breakers trip whenever the amperage surpasses 80% of the full load capacity. This means that a 15-amp breaker can support up to 12 amps, a 20-amp breaker can support up to 16 amps, and so on.

To avoid overloading your electrical system, make sure you’re not placing too many appliances on one circuit. An appliance that has a higher amperage than the circuit it’s on can also cause it to overload.

How to fix an overloaded circuit?

Once you’ve determined your breaker’s load capacity and the total amperage drawing from it, there are a few ways to solve the issue.

  • Move high load, or high amperage, devices to different circuits
  • Turn off electrical devices you’re not using to lessen the load
  • Make sure there are no damaged outlets, cords, or plugs running on the circuit
  • Upgrade your circuit to one that has a greater load capacity

For more information about load capacity, read our other blog How to Determine the Load Capacity of Your Circuit Breaker.

Tripped Breaker

Electricity wants to flow along the path of least resistance. Whenever two or more wires that shouldn't touch come into contact with one another, it can cause a short. Here are a few reasons this phenomenon could occur:

  • Wire to Wire Contact: A hot wire meets another hot wire or touches a neutral wire.
  • Break in Connection: A wire splits because of erosion, water damage, or contact with a sharp object.
  • Damaged Electrical Appliance: The wiring in an appliance or receptacle on the circuit is faulty.

Short circuits are a common wiring problem that can cause electric shocks, burns, and fires if left unrepaired.

How to fix a short circuit?

First, do a thorough examination of all electrical connections and wiring on the circuit. Always make sure to turn the power off to the main breaker before inspecting.

The main things to look for are discoloration or burning on any wiring. Outlet panels and the insulation around them can also show signs of a short, like cracking or brittleness. If nothing is visible on the surface, you can use a receptacle tester to check if your outlets are working properly.

After you’ve determined where the short is occurring, you can get new wires and solder them in yourself. But we suggest hiring a licensed electrician to ensure a safe and proper installation.

A ground fault happens when electricity leaves its intended path and enters the ground. This causes a surge of electricity to flow through the circuit breaker, triggering it to trip. Ground faults risk damage such as electrical fires and shocks.

Ground faults occur for many reasons, but the top three are:

  • Water leakage in or around the breaker panel
  • The circuit box has a damaged or faulty ground fault circuit interrupter (GFCI) device
  • Worn out and damaged electrical wiring

How to prevent ground faults?

Installing GFCI outlets or circuit breakers is a great way to protect against ground faults. GFCIs, or ground fault circuit interrupters, cut power to a circuit as soon as they detect a ground fault.

GFCI breakers deal with ground faults at the source and protect every outlet and receptacle on its circuit. Unlike a normal breaker panel, a GFCI breaker panel is typically larger and has its own test and reset buttons. GFCI breakers can be complex to install, so make sure to consult an electrician if you’re planning to upgrade to GFCI.

GFCI outlets, though, are much easier to install on your own, without the help of a professional. For more in-depth instructions on how to install a GFCI outlet, check out our other blog: How do I Install a GFCI Receptacle?

Troubleshooting Tips

Fixing a Circuit Breaker

Once you’ve identified the reason your circuit breaker tripped, you can begin the process of fixing it. Resetting a tripped circuit breaker is simple with a few easy steps:

  • Identify the tripped breaker. On the circuit breaker box, the tripped breaker will be between the “on” and “off” positions.
  • Turn off all appliances. Make sure to unplug or turn off any device connected to the tripped breaker. This will prevent power surges when you reset the breaker.
  • Test your circuit breaker. Move the breaker from the “off” to the “on” position to reset the power. If the breaker moves easily and feels loose, it is likely defective and needs replacing.
  • Check for loose electrical wiring. If the breaker still trips when you turn it off and on, remove the screws and the access electrical panel to inspect the wiring. If there are any corroded, frayed, discolored, or burned wires then you probably need a new circuit breaker. However, if it is just a loose connection, then you can tighten it with a screwdriver.

Ideally, the problem is a minor one that you can fix yourself at home. However, we still recommend contacting an electrician before performing any electrical service you don’t have experience with. While circuit breaker trips are tedious, they are common and rarely difficult to fix. With our troubleshooting tips, you'll keep your circuit breaker operating the best it possibly can.

How to alarm when power lost to pump outlet (breaker tripped)?

I have a bathroom in my basement that is serviced by a sewage extraction pump. Occasionally, I’ve gone downstairs and found the breaker tripped on the circuit its on. As my wife and I only people in house, not a big deal. But my son and family are moving in for a few months and I really would like to alarm that outlet so it’s clear there is an issue. [BTW, I know the correct thing is to identify the cause of the tripping, and I’m working on that)

Is there anything I can plug into that outlet that will let me know when power is out? (I’m not interested in measuring the current, etc)

There are several different ways to do this, but one of the simplest is just to plug anything at all which communicates with smartthings into that outlet and then use the community – created “simple device viewer” Smart app to notify you when that particular device is no longer responding.

I believe @a4refillpad uses that smartapp for this purpose, and might be able to say more.

And here’s the thread for the smart app if you decide you want to use it.

There are some Beeper alarm devices which are not networked, but you might be able to pick up their alarm with a Leeo acoustic sensor and then have the Leeo notify SmartThings through IFTTT. Quite a few people are doing that for existing smoke alarms or water leak alarms. The problem is the Leeo itself requires mains power so it would have to be plugged in on a different circuit than the one that keeps going out. So that may not be practical for your particular use case.

People used to do this with the first generation of the SmartThings motion sensor, because it would switch itself over to battery when the mains power failed, and you could capture that event. Unfortunately, that device is no longer made.

There is a new nightlight from Centralite which has a similar feature, but I don’t know if anyone has created a custom device type handler for it and it keeps going out of stock. So that one may be a good choice once it’s in full production, but that might not be for a few months.

https://www.amazon.com/Centralite-3-Series-Night-Light/dp/B01G82NWBW

:sunglasses:

Thank you for the fast response! I will try the device Viewer, I’ve got a number of sensors laying around not being used.

Hi, as long as the outlet produces regular events then it can be monitored successfully with the SDV. In your case I would use any smart outlet that has power monitoring capabilities. As that should create plenty of events whilst it is still alive.

This might give you an idea:

With webCoRE you could try a condition using the “stays unchanged” trigger. Typically power is reported when changed or at regular intervals. Find the sweet spot interval and send a notification when the trigger fires (if there would be events, the timer would reset, when events stop, the timer will mature and fire the piston). Start with “stays unchanged for 4-6 hours” and work your way down until you find what time interval works best without giving false alarms

We skipped a wild spring break in Miami Beach. Instead, we had a blast relaxing with retirees in Florida an hour north.

  • Last year, my friends and I spent our spring break an hour north of the madness of Miami Beach .
  • We embraced a "coastal grandmother" aesthetic and hung out with retirees.
  • Although untraditional for college students, we had fun relaxing and avoiding the Miami party scene

Insider Today

Bright and early on a Saturday morning last March, I boarded a flight southbound to Florida with hundreds of other college students.

As a group, we screamed "spring break" — wearing various cuts and colors of college gear and the joyous expressions that can only be attributed to a week away from school stress.

But when we reached the Sunshine State and most of my fellow passengers headed to Miami Beach for drinking and debauchery, my friends and I didn't go with them.

Instead, we headed about an hour north of Miami toward the quiet oceanside community Hillsboro Beach for our own relaxing spring break.

We'd chosen to skip the ragers and bad behavior associated with spring break, especially spring break in Miami. This year, Miami Beach even launched a campaign "breaking up" with spring-break tourists and enforcing new restrictions to crack down on destructive partying.

But we went to a party school and saw plenty of that back home. Now, we were ready to relax with retirees on our last spring break before college graduation.

We leaned into the laid-back vibes for our whole trip and made friends with retirees

The small beach town we stayed in was mostly populated by retirees in their 60s. Even fellow tourists we saw visiting the local businesses rarely seemed to be under 50 years old.

So, when my friends and I showed up to check into our hotel, we received more than a few confused glances.

We got "Are you sure you're in the right place?" and "Are you heading to Miami?" more than once, but when we explained our plan for a relaxing getaway, we were often met with understanding.

We embraced the " coastal grandmother " aesthetic with our white linen shirts and floppy beach hats and spent hours reading on the beach.

When we weren't soaking up the sun, we played card games and Bananagrams and ventured into the (very tame) downtown area for dinner.

Since we slept steps away from a quiet beach, we traded in late, hungover mornings for early alarms to watch the sunrise.

On many of these mornings, we were joined by a new friend: a retired woman who was traveling alone and missing her grandkids back home.

We enjoyed the sunrises together and watched l ocal conservation workers on ATVs protecting hatching sea turtles as they migrated to the water.

If we were hungover on a crowded Miami Beach, we would've missed out on forming this unlikely friendship that crossed generational divides .

Throughout our trip, we spent time with many kind, older tourists and hospitality workers. Once they realized we weren't obnoxious, havoc-wreaking spring breakers, they were more than willing to share their time and stories with us.

By the time I headed home, I knew we'd made the right choice

After a week in our little slice of heaven, it was time to head back.

In our Uber to the airport at 5 a.m., our driver told us he'd come straight from a night of driving around Miami partygoers — and he had horror stories.

He told us he was surprised by our choice for an alternative spring break, but he understood. He'd seen many arrests, sick students, and lost young people in his spring-break driving career.

When we boarded our plane north, we were reunited with our peers, who had the clammy, tired looks only a hangover can bring.

Reinvigorated from our week of R&R, my friends and I listened to their wild tales from Miami while exchanging knowing glances: We'd made the right choice.

Our spring break perhaps wasn't traditional for college kids, but it was just what we needed.
