Abstract
A self testing fault detector having a line side and a load side and a conductive path there between. The apparatus includes a solenoid, which is adapted to move a plurality of contacts disposed in the conductive path from a first position to a second position when the self testing device is powered from the line side; and a processor, which is adapted to energize the solenoid using a first switch and maintain said solenoid in the energized state using a second switch.
