Why does my arc fault breaker keep popping?

Why does my arc fault breaker keep popping?

The two main causes for nuisance tripping at AFCI circuit breakers are improperly wired circuits and incompatibility with electronic devices. Another wiring problem is more of an incompatibility issue than a wiring issue, and it has to do with multi-wire circuits.

Do AFCI breakers wear out?

Nuisance tripping (or tripping without any apparent reason) can occur due to improper wiring, incompatible electronic devices being plugged in the circuit. In some cases, older arc fault breakers can frequently trip due to them wearing out with time.

How do you know if you have a bad arc fault breaker?

If the nuisance tripping stops, then the old arc fault breaker was probably defective. If the arc fault breaker still trips, the electrician then needs to track down the cause by going into each switch, receptacle and light box to look for a wiring problem.

What does AFCI test button do?

The way the “TEST” button on the AFCI outlet works is by creating an arc fault that will cause the outlet to trip immediately. By pressing the button, you will force the outlet to trip, and you will be able to hear the clicking sound. When that happens, the outlet should be tripped and without any power.

Can a surge protector cause an arc fault breaker to trip?

Arc fault circuit breakers are very sensitive, so it doesn’t take much to trip them. A fluorescent light, surge protector, or anything with an LED display could be leaking enough current to constantly trip your arc fault circuit.

How do I reset a breaker that won’t reset?

Unplug all appliances that are plugged into outlets on that circuit and turn off all the lights, then try the breaker again. If it stays on, plug the appliances back in one by one until it trips again, and service or discard the appliance that makes it trip. Check each appliance for overheating when you unplug it.

How often do arc fault breakers go bad?

The sensors inside CAFCI, AFCI, or GFCI breakers typically fail in 15 to 20 years, at which point an electrician should replace the breaker. Testing of CAFCI, AFCI, and GFCI breakers should be performed monthly. Testing involves pressing the breaker’s TEST button and resetting the breaker when it trips.
