A novel apparatus for preventing miswiring of GFCI devices is disclosed. The invention is insertable into the receptacle portion of either a single or duplex GFCI device is operative to provide visual and/or audible indication to an installer or user that a miswiring condition is present. The invention comprises an elongated strip constructed of a nonconducting material such as plastic. The strip includes prongs attached to it either on one or both ends for retaining the strip within the receptacle of the GFCI device. A protruding button is positioned on the inner surface of the strip such that when the device is inserted into the GFCI, the button maintains the test button in a depressed state. This insures that the GFCI will be tested upon initial application of electrical power after installation. If the GFCI is not wired properly, visual and/or audible alarm indicators signal a miswiring condition to the installer.
