A utility control device, such as a light socket, a switch or a plug socket, is designed with universal terminals so that when plugged into a pre-wired utility box (box socket), the terminals will make the proper electrical connections with the premises wiring. Systems and methods are disclosed for arranging the premises power grid such that any device type can be "plugged" into the shells that are pre-wired inside the utility box.
