Arc breakers protect against all arcing conditions, but selectively. Normal arcs should not cause a trip. Nuisance tripping describes an arc fault breaker that mistakenly classifies harmless arcs (such as normal switch operation) as dangerous ones (such as a faulty lamp cord).

The breaker for this dedicated circuit is a Dual Function AFCI/GFCI Circuit Breaker (Siemens, 15 amp). The microwave manual recommends a dedicated 15 amp circuit. The microwave works fine for a few days, then suddenly it starts tripping the breaker within 5 seconds of starting it, no matter what is in it.

There are 8 duplex in the garage gfci protected at the first receptacle and afci protected at the breaker. The start cap on my table saw would trip the afci about once every 20 starts. My brand new circular saw never tripped it.

AFCI Breakers - What you need to know about AFCI Breakers

Although to most customers AFCI breakers are a new thing, they've actually have been around for over a decade. Arc fault circuit interrupters (AFCI's) were introduced as a Code requirement in 1999. Many electrical contractors, inspectors and electricians were much against this being in the Code since it was going to generate lots of call backs due to nuisance tripping—and they were right!

Beginning in 2015, the Canadian Electrical code will require the use of Combination Arc Fault Circuit Interrupters (CAFCIs) in each branch circuit in the home supplying 125V receptacles rated 20A or less (except in the kitchen/bathrooms and sump pump). The CAFCI breaker effectively stops the flow of current before an electrical fire from dangerous arcing can start.

nuisance tripping when certain AFCI breakers are used. This is a by-product of the ground fault protection on AFCI breakers. The load wiring will have some leakage to ground and dimmers will have increased leakage to ground. The leakage current can vary with the type of wiring used and may or may not be an issue depending on the breaker used.

The AFCI technology was not perfect in 2002 and many people complained about nuisance trips. But the technology is continuously being improved to make sure that unwanted hazardous arcing signatures are detected, while at the same time normal arcing signatures that are often present in any electrical circuit won't cause the breaker to trip.

Latest theory. Each AFCI and GFCI outlet that "trips" has a surge protector on it. I read somewhere that a surge on my grid could cause each of these surge protectors to handle the surge, which would cause the AFCI and GFCI to sense that there is a power imbalance hence tripping the breaker.

GFCI devices trip for several reasons. The following best practices can help confirm proper operation and reduce nuisance tripping. Minimize the number of appliances protected by each GFCI. Minimize the circuit length from the GFCI circuit breaker to the receptacle – a maximum conductor length of 150' is good rule of thumb.
