ABSTRACT:
This invention relates to a device allowing a plurality of electrical devices to be operated from the same power source at one time. The device comprises a compact attractive unit housing a plurality of receptacles for receiving electrical plugs commonly used on automotive accessories. An electrically conductive, and rigid bar runs the length of the box and electrically connects the positive pole of each receptacle while mechanically locating the rear of each receptacle.
An electrically conductive plate runs the length of the box, serving as both the ornamental facing of the box and electrically connecting the negative pole of each receptacle to the ground wire. The current entering the box runs through an automatically resetting circuit breaker, which operates to prevent damage to the system from an overload of current being drawn through the device.
