ABSTRACT:
A fail safe electrical receptacle (1) having normally open switches (6) and normally closed switches (7). The normally open switches (6) are wired to a breaker (11) and are located above the slots (2) and (3) while the normally closed position switches (7) are located below the slots (2) and (3). The contact arms (18) wired to the neutral slot (2) are neutral while the contact arms (10) wired to the hot slot (3) are grounded. If the switch levers (9) and (8) located behind the slots (2) and (3) are pressed against the normally closed switches (7), a circuit is not completed and therefore no power is provided to the outlet. However, if the switch levers (9) or (8) are pressed against the normally open switches (6), the circuit between the hot (3) and the ground (17) or the ground (17) and the hot slot (3) is completed and the breaker (11) is tripped.
