Abstract: A self-contained unit intended primarily for tracing the circuit connection between an electrical outlet or lighting receptacle and its corresponding circuit-breaker. The preferred embodiment includes a housing, a male three prong electrical plug, a sound-producing means, a first momentary switch which permits testing of a ground fault interrupt across either a hot wire and a neutral, or across a hot wire and the ground; and a second momentary switch which permits testing of reverse polarity by testing across a neutral and the ground. An alternate embodiment incorporates a single 3-way switch. Adapters are used to temporarily adapt bare wires or a lighting receptacle to a female plug so that the device may be used.
