ABSTRACT:
A ground fault protector includes a conventional ground fault circuit interrupter (GFCI) electronic module which receives operating power over a separate supply circuit to render the protector operable in affording personnel ground fault protection for a circuit whose nominal voltage is inappropriate to power the module. The protector includes contacts operating in both the supply and protected circuits such that, in the event of a ground fault on the protected circuit, both circuits are interrupted. The supply circuit is also equipped to simulate a ground fault condition for verifying operability of the protector.
