Description
Product Overview
The GOUNENGNAIL Ground Bar is a heavy‑duty copper grounding bar designed for wall‑mount installation in electrical panels and distribution cabinets. Constructed from tinned copper, it offers excellent conductivity and corrosion resistance. The bar includes ten 5/16″ terminal positions, each pre‑fitted with a terminal bolt to streamline the wiring process. Rated for up to 7 kV and UL certified, it meets stringent safety standards for both industrial and hobbyist environments.
Usage
This grounding bar is ideal for high‑power distribution panels, low‑voltage control cabinets, ham‑radio stations, and lightning protection systems. Install it on the interior wall of a metal enclosure to provide a solid grounding point for equipment, busbars, and surge protectors. Its compact dimensions (0.16″ W × 7.87″ H) allow placement in tight spaces while maintaining a clear separation from live conductors.
