What is a AFCI breaker and do I need them?

By Bob Millaway, South Jersey Community Expert & REALTOR®

An AFCI (Arc Fault Circuit Interrupter) breaker detects dangerous electrical arcing in your wiring and shuts off power before a fire can start. The National Electrical Code now requires AFCI protection on most residential circuits feeding living spaces, bedrooms, and family rooms. AFCI breakers are different from GFCI breakers, though some combination units offer both types of protection.

Why It Matters

Arcing is a leading cause of electrical fires. AFCI breakers provide protection that standard breakers cannot, and they are now code-required in new construction and major renovations.
