Claim:
1. A system for reducing phantom load in a device, wherein the device receives three or more phases of alternating current from a first electrical power source, the system comprising: outputs configured to provide electric power obtained at least in part from the three or more phases of alternating current; a contactor configured for electrical connection to each phase of the alternating current and for electrical connection to inputs of the device, wherein the contactor is configured to selectively connect each of the phases to a respective input of the device, wherein the outputs are in electrical communication with the contactor; a current detector configured for electrical communication with the outputs, the current detector comprising a timer in communication with the comparator and configured to indicate that a predetermined amount of time has elapsed; and a controller configured to receive the first signal from the comparator and the indication from the timer, and configured to cause the contactor to disconnect each phase of alternating current of the power source from the inputs of the device based on at least the first signal and the indication.
