AFCI circuit breakers are specialty safety devices that have been around for well over a decade, and their job is to prevent fires. They get better and better as time goes on, but they're still not a ...

What is this new circuit breaker, the Arc Fault Circuit Interrupter (AFCI), and how is it better than the circuit breakers (CBs) we have? Let me tell you a little story. Recently, I was working in a ...

Two different technologies protect against two different types of hazard. Ground fault circuit interrupter (GFCI) devices protect people from shock by opening a circuit at a low threshold of leakage ...

Arc-Fault Circuit-Interrupters are relatively new electrical safety devices that first appeared in the 1999 National Electric Code. AFCI devices look very similar to GFCI devices, in that they have a ...

Residential electrical branch circuit breakers incorporate electronic and electrical technology in Arc Fault Circuit Interrupters that can turn off power to prevent fires if arcing occurs. This ...

All references are based on the 2014 edition of the NEC. I may catch some flak for this one, but I’m going to stick my neck out and boldly state that AFCI protection is not required when modifications ...
