Title: Electrical circuit breaker locator with transmitter and receiver

Abstract: A test system for distinguishing a particular AC distribution circuit interrupting device from among a plurality of AC distribution circuits interrupting devices. The test system comprises a transmitter for placing an identification signal on an AC power distribution circuit and a receiver for detecting the identification signal. The transmitter comprises means for generating an FM modulated identification signal, and means for coupling the identification signal to the AC power distribution circuit. The receiver comprises preselector means for selecting a predetermined band of frequencies for further processing, first detector means for detecting a signal within the predetermined band of frequencies, second detector means for detecting a modulating signal, and processor means for processing indications from the first and second detectors, and for activating a discernible indication of receiver operation. The transmitter may further comprise a plurality of indicator means for providing an indication that an electrical receptacle to which the transmitter is connected is wired in accordance with a predetermined arrangement.
