Nvent CP58BX Ground Rod Clamp 10 to 2 Awg Direct Burial

Product Description

The NVENT CP58BX is a silicone bronze ground rod clamp rated for conductor sizes from 10 solid to 2 stranded AWG. It is designed to mechanically and electrically connect a grounding conductor to a ground rod with a diameter of 1/2 inch to 5/8 inch. The silicone bronze construction provides high conductivity and strong resistance to corrosion, making it suitable for buried grounding installations. It carries UL and CSA listings, meeting the compliance requirements typically demanded on commercial, industrial, and residential electrical projects. Licensed electricians and grounding contractors are the primary installers of this fitting.

This clamp is used in grounding electrode systems where a copper or aluminum conductor must be bonded to a driven ground rod. Standard duty applications include residential service entrances, light commercial panels, telecommunications grounding, and utility meter bases. The direct burial listing allows the clamp to be installed at or below grade without requiring additional protective housing, simplifying trench and below-grade grounding assemblies.

Key Features

• Silicone bronze construction for high conductivity and corrosion resistance
• Accepts conductors from 10 solid AWG to 2 stranded AWG
• Compatible with ground rod diameters from 1/2 inch to 5/8 inch
• Listed for direct burial — no additional enclosure required
• UL and CSA listed for use in code-compliant grounding systems

Compatibility

Designed as a standard-duty OEM-style grounding clamp for use with 1/2 inch to 5/8 inch ground rods and conductors ranging from 10 solid to 2 stranded AWG in residential and light commercial grounding electrode systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 250 grounding and bonding requirements. De-energize the system and verify the conductor is isolated before making the connection. Seat the conductor fully in the clamp body and tighten the binding screw securely to ensure a low-resistance mechanical bond. When burying the clamp, ensure the surrounding backfill is free of sharp debris that could damage the conductor insulation.
