Abstract

Controllable electrical outlets and systems and methods for controlling and disabling the electrical outlets. A controllable electrical outlet includes a current sensor, an electrical switch, and a microcontroller. When an electrical load is plugged into the electrical outlet, the current sensor senses the flow of current and a current sense event is reported from the electrical outlet to a central computer. The central computer provides timing and control of the electrical outlet. When a predetermined elapsed time has passed, as measured by the central computer, a timed-out event is communicated from the central computer to the electrical outlet triggering the electrical switch, opening the current path within the electrical outlet such that electrical current no longer flows to the electrical load. Communication between the central computer and an electrical outlet may occur, for example, via existing electrical wiring, wirelessly, or via dedicated communication wiring.
