Abstract
A GFCI device which has reverse wiring protection is provided where no power is present at the face terminals even when the device is reverse wired. The device has a pair of movable bridges connected to its terminals. The terminal bridge pair makes contact with the load and face terminals providing power to these terminals when the device is reset. The device also has a reset lockout feature that prevents it from being reset after having been tripped if the circuit interrupting portion of the device is non-operational.
