Abstract:
1. An electrical receptacle with arc prevention circuitry, including: a receptacle body including a plurality of contacts mounted therein for receiving and contacting the blades of an electrical plug inserted in the receptacle; a zero voltage crossing detector, the zero voltage crossing detector preventing current surges upon insertion of the blades of the electrical plug in the receptacle; at least one motion sensor mounted on the receptacle, the motion sensor detecting movement of a blade of the electrical plug in the receptacle relative to the contacts and outputting a signal in response thereto; an extraction detector operatively connected to the motion sensor, the extraction detector generating a signal in response to movement of the blade; 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; and wherein the extraction detector and switch are operative to de-energize the receptacle when the extraction detector detects extraction of the blade from the receptacle at a rate equal to or greater than a predetermined rate.
