AFCI - Arc Fault Circuit Interrupters | Best Pick Reports

An arc fault circuit interrupter (AFCI) is a relatively new type of breaker designed to detect and stop arcs. Arcing wires are responsible for numerous fires each year, because they generate hot sparks. These fires are especially common in bedrooms where dressers and beds are pushed up against plugs inserted into wall outlets. Over time, the plug and/or the insulating casing surrounding the wire may crack or fray, thus exposing bare wires and creating an arc. Since 2002, AFCIs are required on all new construction.
