Grounding terminal block assembly for multiple services
A grounding terminal block assembly for establishing proper grounding or electrical connection to earth through a path of sufficiently low impedance. The grounding terminal block assembly includes an elongated tubular body with a central longitudinal bore and a plurality of threaded bores extending into the body at right angles to the central bore. Fasteners are threaded into one or more of the threaded bores to provide fastening points for one or more phone, data, or cable TV wires. The top of the tubular body includes a threaded nose portion and lock nut for establishing a secure connection to a service panel. Conversely, for providing a grounding block in a standalone configuration without an associated service panel, legs are provided integral with the tubular body for providing direct connection to a wall or other structure.
