Abstract

A circuit tracer includes a transmitter that places one of first and second signals on an electrical circuit depending on whether the circuit is energized. A receiver detects the signals imposed on the circuit by the transmitter, with the signal strength indicating the proximity of the receiver to the circuit. The receiver detects which of the transmitter signals is present and thereby can also indicate whether power is present on the circuit. The receiver has first and second antennas, one optimized for wide area detection and one optimized for circuit breaker detection. The receiver has an OLED display that remains properly oriented for viewing regardless of the orientation of the receiver housing. The transmitter can have a clamp version that inductively couples to the circuit being traced.
