A plug and an adapter are provided for use with an existing electrical receptacle which has a sleeve extending from a mounting base, with a conductive pin within the sleeve. The adapter has a cylindrical collar receivable snugly over the sleeve of the receptacle, and includes a flange for maintaining the collar in a predetermined position on the sleeve. The plug is elongate, with a first end having a recess for receiving the cylindrical collar, the first end also having an electrically conductive contact member to engage the contact pin. The plug and adapter include retaining means for retaining the plug to the adapter and to permit selective engagement of a plug and retaining means to prevent making incorrect connections between selected plugs and electrical receptacles. The plug further includes attachment means for connection to a cable.
An adapter for adapting a single pole electrical receptacle to receive a plug, the receptacle including a non-conductive mounting base, a non-conductive, substantially cylindrical sleeve extending from the mounting base, and a conductive contact pin positioned generally coaxially within the sleeve, the plug being elongate and having first and second ends, the first end enclosing an electrically conductive contact member which conductively engages the conductive contact pin when the first end of the plug is inserted in the cylindrical sleeve, the plug further having an attachment mechanism for connection to a cable and a retaining mechanism for retaining the first end of the plug in a desired position with respect to the collar, said adapter comprising:
