<p>Receptacles configured to securely mate with hazardous area plugs are provided. The receptacles include a housing, a locking plate, and a sliding lockout key. The sliding lockout key prevents the locking plate from rotating when the receptacle and plug are disconnected or when a standard plug is inserted into the receptacle. When the proper plug is inserted into the receptacle, the sliding key portion is depressed and allows rotation of the locking plate. Upon rotation, pins from the plug contact internal pins of the receptacle and make an electrical connection.</p> |
