Abstract
An electrical circuit identification means for identifying a particular circuit while the latter is normally energized and functioning, said means being usable with a plurality of energized circuits leading to different remote locations in an electrical installation such as a building structure or other facility, where the circuits originate at an energy distribution network that has fuses, circuit breakers or the like adapted to render the circuits dead or unenergized. A portable electrical load device is provided, to be applied to a designated circuit at the remote location where it is to be worked on, said device including a circuit controller or interrupter activated and powered by current from the circuit, so as to periodically interrupt or vary the current passing through the load and thereby cause electrical pulses or surges therein. At the central distribution center, a clip-on meter or other inductive pick-up device is magnetically linked onto the leads of the various circuits that are present, until it shows a reading of the current variations which are being generated by the remote applied load and its controller. The circuit showing such variations is the desired circuit, and can then be disconnected by removing the fuse or opening the breaker, as the case may be.
