Abstract
A universal plug is provided for electrical connection with a receptacle having a configuration selected from a plurality of different configurations such that a conventional electric plug that mates properly with a receptacle having a first of the configurations is prevented from mating properly with a receptacle having a second of the configurations. The universal plug is formed with a first plug component and a second plug component, the first and second components being separable from each other so that each can be manipulated independently of the other for electrical connection to the receptacle. The universal plug will thus mate properly with a receptacle of the first configuration and will also mate properly with a receptacle of the second configuration.
