Abstract
A signaling system employing indicator lamp means and an audible alarm is employed to remind a user to periodically test his GFCIs and to provide information regarding the status of the GFCI. The power lines that supply the GFCI with power are also coupled to the circuits on the PCB to disconnect power to those circuits of the GFCI that trips due to faults or tests.
