ABSTRACT:
A system and method employing a fault circuit interrupter to provide enhanced miswiring protection. The fault circuit interrupter is used with an alternating current (AC) receptacle and comprises first and second source terminals, and first and second load terminals. The fault circuit interrupter also comprises a sensing circuit, which is adapted to selectively enter a fault detection state in response to an imbalance of current flow in the AC receptacle. A latching mechanism is also provided and is adapted to break at least one conductive path between the source and load terminals of the AC receptacle in response to entry of the sensing circuit in the fault state. The sensing circuit is further adapted to maintain the latching mechanism in a condition to maintain a break in at least one of the conductive paths when an AC source is connected to the load terminals instead of to the source terminals.
