GFCI (Ground Fault Circuit Interrupter) and AFCI (Arc Fault Circuit Interrupter) protection are two of the most important safety requirements in the NEC. Each protects against different types of electrical hazards.
GFCI Protection
GFCI protection guards against electrical shock by detecting ground faults — situations where electricity flows through an unintended path, potentially through a person. The NEC requires GFCI protection in bathrooms, kitchens (within 6 feet of a sink), garages, basements, outdoor areas, laundry areas, and crawl spaces.
Recent NEC updates have expanded GFCI requirements to include additional locations. If your home was built before current requirements were adopted, some areas may lack GFCI protection.
AFCI Protection
AFCI protection guards against electrical fires by detecting arc faults — dangerous electrical arcs caused by damaged wiring, loose connections, or overheated conductors. The NEC requires AFCI protection in bedrooms, living rooms, dining rooms, hallways, closets, and most other habitable rooms.
AFCI breakers are installed in your electrical panel and monitor circuits for the specific electrical signatures associated with dangerous arcing.
Dual-Function Protection
Modern dual-function breakers provide both GFCI and AFCI protection in a single device. These are increasingly common in new installations and can simplify compliance with NEC requirements in areas where both types of protection are needed.
