ABSTRACT:
A plug and socket combination positions a plug and electrical cord at an orientation perpendicular to a wall socket, thus reducing the required clearance to substantially that of the plug width without the electrical cord or less than half of the clearance normally required. Two-pronged and three-pronged plug and socket combinations have been developed that are substantially the same width, length, and depth as the typical plug on a two or three wire electrical cord.
