THOMAS & BETTS 8825-TB INSULATED SET CREW CONNECTOR

Description:

The Thomas & Betts 8825-TB Insulated Set Screw Connector is used to connect and effectively bond 3 inch rigid metal conduit (RMC) or intermediate metal conduit (IMC) to electrical boxes and enclosures without requiring conduit threading. Commonly installed in industrial facilities, manufacturing plants, commercial buildings, utility installations, and electrical distribution systems, this insulated connector provides a secure mechanical connection while protecting conductor insulation during installation. Maintenance teams and electrical contractors use this fitting for repair, retrofit, expansion, and replacement of rigid conduit systems.

Applications:

The Thomas & Betts 8825-TB is designed for terminating 3 inch rigid metal conduit or IMC to threadless openings in electrical enclosures. Its nylon-insulated throat reduces conductor abrasion and wire-pulling effort, while captive hex-head set screws provide positive mechanical retention and reliable grounding continuity. The concrete-tight design makes it suitable for switchgear, motor control centers, industrial machinery, process equipment, commercial buildings, and utility raceway installations where conduit rotation is not practical.
