A wire tracing system includes a voltage output source having a director circuit with a plurality of output channels. Each of the output channels outputs a unique voltage signature. A voltage reader/data recorder includes a conductive probe and a data memory that is partitioned into a plurality of data bins. Each of the data bins in the voltage reader/data recorder is associated with one of the voltage signatures output via the output channels of the director circuit, and each of the data bins is configured to store information associated with each of a plurality of wires to which the output channels are respectively connectable. The system and method permit a single individual to rapidly discover the identities of individual wires and cables without having to repeatedly travel back and forth between those extremities.
