  • Power line testing device with signal generator and signal detector
    Patent number: 6466029
    Abstract: A power line testing device has a signal generator that is adapted to be connected to one of a plurality of AC branch circuits, and generates an identification signal. This identification signal will be strongest in the branch circuit of origin. A receiver of the testing device senses the strength of the identification signal, compares that strength to a stored identification signal, and is therefore able to identify to which AC branch circuit the transmitter is connected.
