ABSTRACT:
An enclosure which supports a standard receptacle for receiving a standard plug and a handle which can be positioned to a first position or a second position is provided. The handle, when in the first position, blocks the removal or insertion of the plug into the receptacle. In the fist position, the receptacle can be selectively connected by a user to a source of power. When the handle is in the second position, the plug can be removed or inserted into the receptacle and the receptacle is prevented from being connected to the source of power. The apparatus includes a receptacle, a switch for turning power to the receptacle on or off, a member coupled to the housing and having a first position which prevents the plug from being inserted into or removed from the receptacle and a second position which allows the plug to be inserted into or removed from the receptacle, and a connector coupled to the member and to the switch to enable the switch to connect the receptacle to a source of power when the member is in the first position. The apparatus also includes a housing for containing the receptacle and mounting lugs for mounting the apparatus.
