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).
GFCI and AFCI Explained. As new technology brings us new tools to make our lives easier, it also provides new devices to keep us safer in our homes. GFCI protected electrical receptacles and AFCI protection circuit breakers are small technological wonders.hat is where GFCI and AFCI devices come into play. GFCI Electrical Outlets-A GFCI outlet (GFCI stands for Ground Fault Circuit Interrupt) is a special electrical outlet device that provides much greater protection from electrical shock than a standard electrical outlet does.
