Abstract
Abstract An electrical protective panel assembly comprising a conductive rectangular enclosure containing a conductive rectangular frame for mounting a plurality of electrical protective devices in the enclosure. Electrical ground contact assemblies are located at the corner regions of the panel assembly and each includes means for readily electrically connecting thereto the ground wires of equipment to be protected by the adjacently located protective devices. Alternatively, one or more such contact assemblies are mounted on the inner wall of the enclosure, on frame members at the corner sections of the frame structures or on lateral members of the frame structure. The contact assemblies can be mounted in position during original manufacture of the panel assembly or in the field. The ground contact assemblies each includes a conductive bracket having a terminal strap conductively and removably mounted therein. The strap carries one or more terminal strips with means for individually connecting a plurality of ground wires to the terminal strap. The terminal strips are each selectively and independently positionable in predeterminedly oriented positions to facilitate ground wire connections therein. Preferably the ground contact assemblies are removably mounted on frame members at the corner sections of the frame structure adjacent the point of entry of the wires into the enclosure and a plurality of these assemblies can be mounted in side-by-side or back-to-back relation on each corner or side of the frame structure. In panel assemblies in which the wiring enters the enclosure elsewhere than in the corner regions thereof, the contact assemblies are mounted on an internal support structure immediately adjacent the point of entry of the wiring.
