Nsi Industries 1312-B Brass Ground Clamp 1-1/4 to 2 Inch

Product Description

The NSI INDUSTRIES 1312-B is a brass ground clamp designed to establish a reliable grounding connection on water pipe or conduit systems. Constructed from brass, this clamp accommodates pipe sizes ranging from 1-1/4 inches to 2 inches, making it suitable for a range of residential and light commercial grounding applications. Electricians install this clamp as part of a grounding electrode system, securing the grounding electrode conductor to a metallic water pipe. The brass construction provides good conductivity and corrosion resistance in typical indoor plumbing environments.

This ground clamp is used in residential and commercial electrical installations where a metallic water pipe serves as a grounding electrode. It is intended for use by licensed electricians during new construction, service upgrades, or grounding system repairs. The clamp fits pipe diameters from 1-1/4 inches to 2 inches and is suited for attachment to copper or galvanized steel water pipe in compliance with grounding electrode system requirements.

Key Features

• Brass construction for durability and electrical conductivity
• Fits pipe diameters from 1-1/4 inches to 2 inches
• Designed for grounding electrode conductor attachment to metallic water pipe
