Arc fault circuit interrupters (AFCIs) protect a home against electrical fires. ACFIs protect against fire-causing arcing much like GFCI’s protect against stray current. When an arc is detected, power to the circuit is interrupted. Arcing can be caused by any number of factors, including damaged or worn wires, incorrect wiring, and loose or wet connections. Newer AFCIs are able to distinguish between dangerous arc faults and normal arcing caused by fluorescent lighting and some dimmers and switches.
"AFCI’s give great fire protection to homes with older wiring,” says Mike Holt, licensed electrician, electrical inspector, instructor, and founder of Mike Holt Enterprises, providers of educational resources to those in the electrical profession and related fields. Currently, the National Electric Code requires AFCI breakers for circuits providing power to bedrooms, living rooms, family rooms, and other common rooms in new construction. The cost for an AFCI breaker varies by manufacturer, but consumers can expect to pay around $30 to $35 apiece.
