Thomas Betts TC223SC Emt Conduit Connector 1 Inch

Product Description

The THOMAS BETTS TC223SC is a straight, set screw EMT conduit connector designed for secure mechanical termination of electrical metallic tubing at enclosures, junction boxes, and panels. Built from die cast zinc, this 1-inch trade size connector provides a concrete-tight seal suitable for demanding installation environments. The set screw connection method delivers a reliable mechanical grip without requiring specialized crimping tools, making it a fast and straightforward choice for licensed electricians working on commercial and residential wiring systems.

This connector is rated for use with EMT conduit in concrete-tight applications, making it appropriate for installations where the conduit entry point may be exposed to moisture, dust, or embedment in concrete. It is commonly installed where EMT transitions into metallic enclosures, panelboards, or outlet boxes. The non-insulated, straight body design is standard for general electrical rough-in work across both residential and light commercial projects.

Key Features

• Concrete-tight construction suitable for embedded and wet-location conduit terminations
• Set screw connection provides solid mechanical attachment without crimping tools
• Die cast zinc body offers corrosion resistance and durability
• Straight connector profile for direct, in-line EMT-to-enclosure termination
• Non-insulated design compatible with standard EMT installation practices
• 1-inch trade size fits standard 1-inch EMT conduit

Compatibility

Designed as an OEM-style replacement and standard-use connector for 1-inch EMT conduit systems in residential and commercial electrical installations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for EMT fittings and enclosure connections. De-energize all circuits and verify lockout/tagout procedures before connecting or disconnecting conduit at any enclosure. Tighten the set screw securely to ensure proper mechanical connection and to maintain the concrete-tight rating. Do not use with conduit types other than EMT.
