An AFCI is a special breaker intended to provide fire protection caused by arcing faults (small sparks) by recognizing characteristics unique to arcing and by functioning to de-energize the circuit when an arc fault is detected. An AFCI recognizes the “signature waveform” of an arcing fault and shuts the power off to the circuit to protect against fire. As of the 2008-NATIONAL ELECTRIC CODE, AFCI circuits are required in all newly constructed homes in the following areas; family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, or similar rooms or areas. However, if you have an older house, you can still take advantage of the benefit of an AFCI protected circuit. In many cases, Hufnagel Electric can install this innovative safety technology today so your family will be protected by the best technology available today.
