Abstract
A self test (ST) ground fault circuit interrupter (GFCI) provides a half wave rectifier for powering circuitry for determining and annunciating end of life (EOL) of the GFCI regardless of a shorted diode bridge or opening of a printed circuit board (PCB) trace. A fuse resistor is provided to open before an open PCB trace can occur. A microprocessor-controlled heat-conducting circuit is provided adjacent to a thermal fuse to controllably open the thermal fuse and remove power from face receptacle contacts and load terminals when EOL occurs.
