Overview

The ABB Installation Products Type JAB Ground Rod Clamp (SKU: JAB34C) provides a secure, corrosion-resistant grounding connection for electrical systems. Cast from high-strength copper alloy, this clamp accommodates dual ground rod sizes (3/4" and 5/8") and supports conductor sizes from 8 AWG solid to 3/0 AWG stranded. The JAB34C features a hex head bolt design with 5/16–14 UNC-2A thread for reliable torque retention in direct burial applications. Its long bearing surface ensures stable contact with ground wires, minimizing resistance and enhancing system safety. Designed for utility, industrial, and commercial grounding systems, this clamp is ideal for installations requiring durable, low-maintenance earth connections. The compact dimensions (max bolt A: 2 7/32") and robust construction make it suitable for confined spaces while maintaining high mechanical strength. Compatible with both copper-clad and galvanized ground rods, the JAB34C delivers consistent performance in harsh environments where electrical safety is critical.
