A test system for distinguishing a particular AC distribution circuit interrupting device from among a plurality of AC distribution circuits interruption 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 (UB1) for generating an FM modulated identification signal, and means (T1, C10) for coupling the identification signal to the AC power distribution circuit. The receiver comprises preselector means, first detector means, second detector means, and processor means for activating a discernible indication of receiver operation. The transmitter may further comprise a plurality of indicator means (D3, D6, D9) for providing an indication that an electrical receptacle to which the transmitter is connected is wired correctly.
