If employing an arc-fault circuit breaker, it must be a “combination-type.” See below for additional information. If your arc-fault breaker has a white pigtail, connect this pigtail to the neutral bus, just as you would a regular neutral wire. A “COMBINATION” Arc-Fault Circuit Breaker is NOT equivalent to a “DUAL-FUNCTION” Circuit Breaker. Arc-Fault Circuit-Interrupter Protection (AFCI) The requirements for AFCI protection first came into the NEC in the 1999 edition, with an effective date of January 1, 2002. After having been slowly phased in over the past 3 NEC Code cycles, these new arc-fault breakers are now required on almost every 120V circuit in the finished space of the house. Arc faults can range in power from a few amps up to thousands of amps, and are highly variable in strength and duration. According to the National Electrical Code, AFCI (arc-fault circuit interrupter) breakers are required on almost all 120V circuits within a finished space of a home. Outlet Branch Circuit (OBC) AFCI Devices are an alternative solution to AFCI Breakers. I've read that one shouldn't use GFCI protection for a refrigerator, but I know that AFCI breakers do include ground-fault protection (at a 30mA threshold, as opposed the 6mA threshold for GFCI breakers or AFCI/GFCI dual breakers). Panels equipped with a “plug-on neutral” allow arc-fault breakers to connect directly to the neutral bus without a pigtail. Eaton now offers a system combination-type AFCI.
