The well-known crack of a rifle, whose ball came skipping along the placid surface of the strait, and a shrill yell from the island, interrupted his speech, and announced that their passage was discovered.
An arc fault circuit interrupter (AFCI) is a circuit breaker that breaks the circuit when it detects an electric arc in the circuit it protects to prevent electrical fires. An AFCI selectively distinguishes between a harmless arc (incidental to normal operation of switches, plugs, and brushed motors), and a potentially dangerous arc (that can occur, for example, in a lamp cord which has a broken conductor).
Some of us may be familiar with a GFCI -- ground fault circuit interrupter -- but as of 2011, an AFCI -- arc fault circuit interrupter -- may be a fairly new term. An AFCI outlet can be installed in a home that has an older-style main electrical box that utilizes fuses instead of circuit breakers.An AFCI outlet provides arcing protection from the electrical items that may be plugged into the outlet.ndividual AFCI outlets can be installed in homes that have an older main electrical box that contains fuses instead of circuit breakers. Some localities require AFCI protect on electrical circuits in bedrooms in new construction.
