Thomas Betts TC228SC Emt Conduit Connector 3 Inch

Product Description

The THOMAS BETTS TC228SC is a straight, set-screw EMT conduit connector designed for secure, concrete-tight connections in commercial and industrial electrical installations. Constructed from die cast zinc, this non-insulated connector accepts 3-inch trade size EMT conduit and fastens without threading or crimping tools. The set-screw design clamps directly onto the conduit wall, creating a rigid, low-resistance mechanical bond suitable for concrete-tight applications. Licensed electricians and electrical contractors install this fitting where EMT terminates at enclosures, junction boxes, or panels requiring a dependable mechanical connection.

This connector is rated for 3-inch trade size EMT and is suited for use in commercial, industrial, and institutional wiring systems. The concrete-tight construction makes it appropriate for installations in slabs, poured walls, or other embedded conduit runs where moisture intrusion at the fitting must be minimized. The straight profile simplifies box and enclosure entry without offsetting the conduit run.

Key Features

• Set-screw connection type for fast, tool-minimal installation without threading
• Die cast zinc construction provides corrosion resistance and mechanical durability
• Concrete-tight rated for embedded and moisture-exposed installations
• Straight connector shape for direct conduit-to-enclosure entry
• Non-insulated design for standard EMT termination applications
• 3-inch trade size fits standard 3-inch EMT conduit

Compatibility

Designed as an OEM-style replacement and standard fitting for use with 3-inch trade size EMT conduit in residential, commercial, and industrial electrical systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits in the affected enclosure before making conduit connections. Tighten the set screw to secure the conduit using the appropriate hex key or screwdriver; do not overtighten, as die cast zinc fittings can crack under excessive torque. Verify the concrete-tight rating meets the requirements of your specific installation environment before embedding.
