Bridgeport Fittings SGB383CL Split Grounding Bushing 1 in

Product Description

The BRIDGEPORT FITTINGS SGB383CL is a 1-inch insulated split grounding bushing designed for use with rigid conduit, IMC conduit, and EMT fittings. The split design allows installers to apply the bushing before or after wire pull-through, reducing downtime during upgrades to existing power and data systems. Constructed from ball-burnished zinc die cast with an aluminum lug rated for 14 to 4 AWG conductors, the SGB383CL includes stainless steel hardware and a UV-stabilized nylon insulator rated to 150 degrees C. It is built to OSHA-recognized and NRTL-listed electrical standards.

This bushing is suited for commercial and industrial electrical installations where grounding continuity must be maintained on 1-inch rigid, IMC, or EMT conduit systems. The split-body construction makes it especially practical in retrofit and upgrade scenarios where wire has already been pulled and traditional bushing installation is not feasible. Licensed electricians performing panel work, conduit terminations, or system upgrades in facilities will find this fitting well-suited to confined or live-adjacent work environments.

Key Features

• Split design allows installation before or after wire pull-through
• Ball-burnished zinc die cast body provides a smooth interior surface to protect conductor insulation
• Aluminum lug accepts 14 to 4 AWG grounding conductors
• UV-stabilized nylon insulator rated to 150 degrees C
• Stainless steel hardware for corrosion resistance
• OSHA-recognized and NRTL-listed to electrical industry standards

Compatibility

Designed for use with 1-inch rigid metal conduit, IMC conduit, and EMT fittings. Accepts grounding conductors from 14 to 4 AWG.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for grounding and bonding. De-energize the circuit and verify the absence of voltage before working on conduit terminations. The split bushing halves should be seated fully and hardware tightened evenly to ensure a secure, compliant connection. Do not use this fitting as a substitute for listed conduit connectors or locknuts.
