33. A self testing fault detector having a line side and a load side and a conductive path there between, said apparatus comprising:
-
a solenoid, adapted to move a miswire prevention plate from a first position operable to prevent closure of at least one contact disposed in said conductive path, to a second position operable to allow closure of said at least one contact when said self testing fault detector is powered from the line side; and
a processor, adapted to perform a periodic self test to determine the status of the self testing fault detector without interrupting power to the load side. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
