Grounding terminal block assembly for multiple services
A grounding terminal block assembly for securing to an existing ground wire to provide additional connection points for electrical systems such data, cable TV, and phone lines. The grounding terminal block assembly includes an elongated grounding bar with a plurality of threaded bores extending laterally therein. Fasteners are threaded into one or more of the threaded bores to provide connection points for ground wires from one or more electrical systems. A channel on one end of the grounding bar includes a slotted headless set screw for establishing a secure connection to an existing ground wire. Legs are provided integral with the grounding bar for providing direct connection to a wall or other structure. A detachable insulating cover is secured to the grounding bar to shield the grounding body and all wiring connections.
