Close-up of an AFCI. AFCIs protect against fires caused by arcing faults and are now required in new or remodeled bedrooms. … AFCIs are designed to sense an arc, which is an electrical “leak” caused when a hot wire touches a neutral or ground but doesn’t trigger the circuit breaker.
What is a combination type AFCI?
Murray Combination Type Arc Fault Circuit Interrupters. The Combination Type AFCI differs from the Branch/Feeder AFCI in its ability to detect series arcing faults. … Combination AFCIs provide protection against the high-energy parallel (line-to-neutral and line-to-ground) arcing and low-energy series arcing.
