Southwire 622B Ground Clamp 1.25 to 2 Inch Conduit

Product Description

The SOUTHWIRE 622B is a ground clamp designed to bond metallic conduit to grounding conductors in electrical installations. It accommodates conduit sizes from 1.25 inches to 2 inches, making it suitable for a range of common rigid metal conduit and intermediate metal conduit runs. Electricians use this clamp to establish a reliable low-impedance ground path as required by the National Electrical Code. The clamp is sized to fit securely on standard trade-size conduit without modification, supporting fast, compliant terminations in both new construction and retrofit work.

The 622B is intended for use in residential, commercial, and light industrial electrical systems where conduit grounding is required. It is well suited to panel feeders, service entrance conduit, and branch circuit raceways where conduit sizes fall within the 1.25-inch to 2-inch range. Licensed electricians and electrical contractors install this clamp as part of equipment grounding assemblies to meet bonding requirements on metal raceway systems.

Key Features

• Fits conduit from 1.25 inches to 2 inches trade size
• Designed for bonding metallic conduit to grounding conductors
• Supports NEC-compliant equipment grounding and bonding installations
• Suitable for rigid metal conduit and intermediate metal conduit applications

Compatibility

Designed as an OEM-style replacement or direct-use ground clamp for metallic conduit systems in the 1.25-inch to 2-inch trade size range.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and local codes. De-energize all circuits and verify absence of voltage before working on grounding and bonding connections. Ensure the clamp is tightened securely to make firm metal-to-metal contact with the conduit surface for a reliable ground path. Inspect the conduit surface for corrosion or paint that could impede bonding before installing the clamp.
