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).
Combination AFCI circuit breakers detect the arcing condition and turn off the circuit, thus providing the enhanced protection.

We have to install these on this job in Arlington Hts. Il. , the inspector says they are required by the 2008 NEC. The supply house has heard of them twice.
