Abstract
An electrical receptacle includes at least one motion sensor for detecting movement of a blade of an electrical plug in the receptacle, an extraction detector operatively connected to the motion sensor for generating a signal in response to movement of the blade at a predetermined rate, a position detector operatively connected to the motion sensor for determining the position of the blade in the receptacle, a switch operatively connected to the extraction detector and the position detector for de-energizing the receptacle when the extraction detector detects extraction of the blade from the receptacle at a rate equal to or greater than the predetermined rate and wherein the extraction detector and switch are operative to de-energize the receptacle in less than six milliseconds when the extraction detector detects extraction of the blade from the receptacle at a rate equal to or greater than the predetermined rate.
