Abstract: An electrical receptacle includes a printed circuit board (PCB), a power control unit coupled to the PCB, AC electrical conductors, and an electrical receptacle coupled to the PCB. The electrical contacts are in electrical communication with respective ones of the electrical conductors. A first portion of each electrical conductor is coupled to a power source and a second portion of each electrical conductor is coupled to respective ones of the electrical contacts. The power control unit includes a controller and a switch, the switch operable to selectively establish continuity between the first and second portions of at least one of the electrical conductors. The controller is configured to selectively place the switch into either a closed position or an open position in response to a signal received from an environmental or occupancy sensor.

Abstract: A system and method are provided for managing electrical power consumption by individual electrical circuits in a building. The system includes a power control device in electrical communication with a multi-circuit power infeed and a multi-circuit power output, each of which includes at least two electrical conductors on separate circuits. The power control device includes respective electrical switches associated with the conductors of the power infeed and power output, an electronic communications module, and a computer processor in communication with the switches and the communications module. The processor is operable to open and close the electrical switches independently, in response to an occupancy signal and/or a trigger or scheduled event stored by the power control device. When a period of non-use is detected or anticipated, the power control device de-energizes one or more circuits, to limit unnecessary energy consumption within the system. A receptacle-level power control is also disclosed.
