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 two prong electrical plug, and a sound-producing means. A second embodiment includes a male three prong electrical plug. A third embodiment incorporates a 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. Adapters are used to temporarily adapt bare wires or a lighting receptacle to a female plug so that the device may be used.
