AFCI breakers, common to newer homes, provide added protection to homes in the event of an arc-fault. AFCI stands for “Arc Fault Circuit Interruptor.” If there’s an arc fault, the AFCI breaker “trips” the circuit, turning off power to help prevent the possibility of an electrical event or fire. The video above explains how to best test AFCI breakers to ensure they’re working properly. Technically, manufacturers typically recommend testing these breakers every thirty (30) days. If they don’t “trip,” replacement by a qualified electrician is advised.
