A device for identifying individual cables communicating between many remote locations to one central location using the building AC ground circuit to communicate between the remote location and the central location. The device includes a plurality of tubes adapted to engage individual cables and corresponding light-emitting diodes (LED) adjacent to each tube. A needle in the tube provides communication with the wire of the insulated cable. A remote interconnection cable provides connection between cable remote ends, and the building ground circuit concurrently providing a means to prevent engagement with the energized AC circuits.
