Overview

The ABB E-Z-Ground Ground Grid Copper Compression Connector (SKU: GG40250-21) is engineered for robust grounding connections in industrial and utility applications. Constructed from high-conductivity bronze alloy, this connector is specifically designed for direct burial and is suitable for connecting perpendicular runs of stranded copper cable to ground rods. It accommodates a cable range of 4/0 AWG or 250 kcmil and is compatible with 1/2" and 5/8" ground rods. The connector is installed using hydraulic tools with hex crimp dies, requiring two crimps per end for secure termination. The heavy-duty cast copper construction ensures durability in demanding environments, including high-corrosion and high-stress applications. This connector replaces exothermic welds and is ideal for electrical substations, renewable energy projects, industrial facilities, and utility grounding systems. It provides a reliable, low-resistance connection that maintains integrity over time, even in harsh conditions. The connector’s design allows for efficient installation with minimal tools, reducing labor costs and project timelines. Dimensions are L1: 4 15/16 inches and L2: 3 1/4 inches, optimizing space while ensuring a secure fit. The required die for the ground rod is 87H, and the die for the cable is also 87H, ensuring compatibility with standard hydraulic crimping equipment. Note: This connector is not rated for galvanized ground rods or galvanized cable, as it is specifically designed for copper applications to maintain optimal conductivity and corrosion resistance.
