Southwire CBGI100 Insulated Grounding Bushing 1 Inch

Product Description

The SOUTHWIRE CBGI100 is an insulated grounding bushing designed for use on threaded rigid metal conduit and intermediate metal conduit entries. It provides a grounded, insulated throat to protect wire insulation from sharp conduit edges while establishing a reliable ground path at the point of entry. The bushing is sized for 1-inch conduit trade size and is installed by licensed electricians during service entrance work, panel terminations, and conduit stub-up applications where code-required grounding continuity must be maintained at each enclosure knockout.

This insulated grounding bushing is suited for residential and light commercial electrical installations. It is commonly used at load centers, junction boxes, and service enclosures where 1-inch rigid or IMC conduit terminates. The lug on the bushing accepts a grounding conductor, allowing a direct bonding connection to the enclosure without relying solely on mechanical contact between conduit fittings.

Key Features

• Insulated throat protects conductor insulation at conduit entry points
• Integrated grounding lug for direct bonding conductor attachment
• Sized for 1-inch trade size threaded rigid metal conduit and IMC
• One-year limited warranty
• Country of origin: China

Compatibility

Designed as an OEM-style replacement fitting for 1-inch threaded rigid metal conduit and intermediate metal conduit terminations at electrical enclosures and panel knockouts.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC). De-energize the circuit and confirm the panel or enclosure is locked out before beginning work. Thread the bushing onto the conduit end before pulling conductors, and torque to the fitting manufacturer recommendation using an appropriate conduit wrench. Attach the grounding conductor to the lug and ensure continuity to the enclosure ground bar.
