A transmitter that is electrically connected to a circuit and an associated receiver is used to identify an element of that circuit in the presence of other circuits. This may be used in AC or DC systems that are powered or not to identify or trace circuit elements such as lines, junctions, switches, fuses, or breakers. One version that identifies the circuit breaker of the circuit connected to the transmitter in a powered AC distribution system.
