Arc Fault Circuit Interrupter (AFCI)

Arc fault protection, or arc fault circuit interrupters (AFCI), has been around for some time, but if your home was built or remodeled before 2005, you might not be familiar with it.

Arc-Fault Circuit Interrupter Breakers

According to the National Electrical Code (NEC), Arc-Fault Circuit Interrupter Breakers (AFCI) are now required in all new constructions. These breakers are different from the ground fault interrupter (GFI) breakers already installed in your home. While GFI breakers protect you from electrical shocks, AFCI breakers are designed to safeguard your home from fire hazards.

How Do AFCI Breakers Work?

GFI breakers protect against electrical currents that occur when hot wires touch ground wires by tripping the circuit breaker and shutting off the power. However, if the hot wire doesn’t maintain consistent contact with the ground or neutral wires—due to deteriorating insulation, loose wires, or corrosion—an arc of heat can form, creating a potential fire hazard. AFCI breakers can detect these arcs and trip the breaker to prevent a fire from starting.

In new or remodeled wiring, many locations will require both GFCI and AFCI protection. This can be achieved by installing AFCI circuit breakers along with GFCI receptacles in specific locations, or by using combination AFCI/GFCI circuit breakers to provide both types of protection to the entire circuit.

Adhering to Code requirements for both AFCI and GFCI protection is essential when extending or updating a wiring system.

The 2017 National Electrical Code® (NEC) mandates AFCI protection for 15 and 20 amp circuits that serve outlets and devices in all areas of new residential construction, excluding bathrooms, garages, and outdoor areas.

When replacing receptacles in areas where AFCI protection is now required, the new receptacle must include AFCI protection.
