Description
Product Overview
The GOUNENGNAIL Copper Ground Bar is engineered for demanding electrical environments where safety and reliability are paramount. Constructed from high‑conductivity tinned copper, the bar measures 0.157″ x 2.36″ x 7.87″ and offers twelve precisely spaced terminal positions (5/16″ pitch) that accommodate standard grounding bolts. Each terminal is paired with SM40 polyester insulators made from UL‑approved material (QMFZ2.E252110), delivering a continuous voltage rating of up to 7.2 kV and an impulse rating of 7.4 kV. The wall‑mount configuration reduces panel depth, making it perfect for crowded distribution boards, ham‑radio rigs, and industrial control cabinets. All terminal bolts are pre‑assembled before packaging, eliminating on‑site mess and ensuring a quick, secure fit.
Usage
Designed for both commercial and residential applications, this grounding bar excels in power distribution panels, UPS systems, and renewable energy inverters. Installers appreciate the low‑profile wall mount that fits within a 0.16″ depth, allowing additional components to be placed behind the bar without compromising clearance. The bar’s robust copper construction handles high fault currents, making it suitable for lightning protection systems, heavy‑duty machinery grounding, and critical communication equipment. Whether you are a professional electrician wiring a new sub‑panel or a hobbyist setting up a ham‑radio station, the GOUNENGNAIL bar provides a dependable grounding point that meets UL standards.

FAQ
What size wire can be used with the terminals?
The terminals accept standard grounding bolts up to 1/4″ diameter, compatible with typical copper grounding wires used in residential and commercial panels.
Is the bar suitable for outdoor installations?
While the copper bar itself is corrosion‑resistant, it is intended for indoor, wall‑mounted applications. For outdoor use, pair it with a weather‑proof enclosure to maintain UL compliance.
Can the bar be mounted on a vertical surface?
Yes, the bar includes pre‑drilled mounting holes that align with standard panel studs, allowing secure vertical installation on any metal or wooden surface.
Does the product include all necessary hardware?
Each kit contains the copper bar, twelve pre‑assembled terminal bolts, and the UL‑rated insulators. Mounting screws and additional grounding clamps are sold separately.
What warranty does GOUNENGNAIL offer?
The grounding bar comes with a one‑year limited warranty covering material defects and manufacturing errors, backed by our dedicated customer support team.
