This device allows you to quickly find which breaker controls an electrical receptacle. Simply plug the transmitter into the receptacle and head over to your breaker box. Hold the receiver up to the breakers in the breaker box and move it around until you have the strongest signal. That is the breaker that controls the circuit.
I have had a few issues with the device. First, it only works in a grounded plug and many of the receptacles in the house I am renovating are not grounded. AND… I would really like to be able to trace the lighting circuits.
One cool feature is that the transmitter can also be used to see if the receptacle was wired correctly.
