A leakage current detection interrupter (LCDI) having open neutral detection. In one embodiment, the LCDI is formed in a plug and includes a circuit interrupter means for breaking a conductive path between line side phase and neutral conductors and load side phase and neutral conductors. A tripping means is coupled to operate the circuit interrupter means to break the conductive path upon the detection of the opening of the line side neutral conductor referred to as open neutral condition. The tripping means, which uses the neutral path as a return path if leakage current is detected, will, with this invention, use a line side ground conductor as a return path if the neutral path is broken anywhere between a service panel entrance and the plug. In response to the opening of the line side neutral conductor or leakage current, the LCDI interrupts the flow of current to a load such as a window air conditioner.
