Abstract
A tradesman may identify which circuit is connected with any number of outlets or other terminations in an electrical wiring system, such as commonly found in buildings, through the use of a handheld, carry-about detector-indicator device. Operation relies upon having prearranged excitation of each of several circuits typical of the usual building power distribution through introducing unique tag signals into each of the various wiring circuits by connecting a tag signal exciter to the building's wiring, usually at the main power box. The tradesman then may merely walk about and 'plug' the indicator into various outlets or, by a suitable adaptor or clip leads, connect with lamp receptacles and the like, whereupon the indicator will give display of a 'number', for example between '1' and '8', or some other such display which will promptly tell the user which circuit his detection indicator is coupled with.
