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).
Conversely, if the voltage is below 70. volts, the electronics within the AFCI / GFCI will not be powered such that they can offer. the correct arc fault or ground fault protection. In either case, the thermal magnetic. protection (overcurrent / short circuit protection) will continue to be in place.
