Abstract
Abstract A method and apparatus for wiring a building structure including a factory-assembled wiring harness having a trunk cable portion and a plurality of branch cable portions, each branch cable portion having an electrical terminal device, such as a switch or outlet, permanently electrically secured to the end thereof. Installation is facilitated by individually packaging the electrical terminal devices and a portion of the branch cable secured thereto in individual plastic bags, and wrapping the entire harness in an elongate plastic envelope which is then rolled up from one end to the other. In the preferred example, the wiring harness is placed on a grid-like ceiling module and unrolled longitudinally from one end to the other. The envelope is opened and the individual terminal devices are extended outwardly therefrom and tacked in place and left hanging around the outside of the ceiling module. After the ceiling module is disposed on the walls, the electrical terminal device packages are opened to allow the devices to fall to their full vertical extension and secured in place. Outer peripheral notches and protective plates are employed to provide raceways or channels for the electrical wiring.
