SELF-TESTING AUTO MONITOR GROUND FAULT CIRCUIT INTERRUPTER (GFCI) WITH POWER DENIAL

摘要

A self-testing fault detector having a line side and a load side and a conductive path there between is provided. The self-testing fault detector includes an automonitoring circuit electrically coupled to a fault detection circuit and an interrupting device and it continuously monitors one or more signals to determine an operating state of the fault detector. At least one of the monitored signals includes a fault detection signal, wherein if said automonitoring circuit determines that the fault detection circuit is not properly driving the interrupting device, the automonotoring device converts an input-output port receiving the fault detection signal from an input to an output and drives the interrupting device into a tripped condition using the input-output port.
