Abstract
A GFCI device (10) which has reverse wiring protection is provided where no power is present at the face terminals (16, 24) even when the device is reverse wired. 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.
