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.
