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).
Why Use AFCI. An AFCI outlet may reduce the risk of fire in your home caused by arcing. Arcing faults caused by wiring in older homes or wiring that has not been installed correctly can cause a fire. Many home fires may be attributed to faulty wiring.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.
