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).
The QOâ¢ and Homelineâ¢ Combination Arc-fault Circuit Interrupters, also. referred to as CAFCIs, were developed to meet the NEC 2005 requirements. effective January 1, 2008. Types of AFCIs Arc Fault Circuit Interrupters (AFCIs) are devices intended to mitigate the. effects of arcing faults by functioning to de-energize the circuit when an arc-. fault is detected. It is important to understand which device you have before. attempting to determine the cause of AFCI tripping.
