Abstract
A system and method of electrically interconnecting a multiplicity of electrical lighting fixtures is disclosed in which up to three phase AC power and up to five conductors (i.e., one conductor for each phase, a ground conductor, and a neutral conductor) is used in such manner that selected groups or branches of the lighting fixtures may be independently, selectively controlled, and such that wiring to the fixtures and control switches may be readily plugged into place.
