Abstract
Methods and apparatus can be used to turn an existing 240 VAC or 480 VAC/600 VAC outlet into two or more time-sharing, i.e., one operating at a time, outlets. An AC switch box with two time-sharing outlets can be made with either a mechanical switch for switching which load receives power, or automatically, by a microcomputer system, for example. In the automatic AC switch box, the non-favored outlet may be typically powered on unless a load is detected at the favored/default outlet, when power to the non-favored outlet is automatically disconnected until the load is reduced or eliminated.
