Steel City TC121A – Frequently Asked Questions
1) Will a set screw EMT connector work on rigid or IMC conduit?
No. The Steel City TC series is built for electrical metallic tubing only. Set screw fittings grip the smooth outside wall of EMT; rigid and IMC are threaded conduit and need threaded couplings or a threaded hub fitting instead. Using a set screw EMT connector on rigid will not give you a proper mechanical or grounding connection.
2) Is this EMT connector UL listed for commercial work?
Yes, the Steel City set screw EMT connector carries UL listing E16592, which is what an inspector or a spec writer on a commercial job will be looking for on the fitting.
3) Are set screw EMT connectors OK in a damp or outdoor location, or do I need compression?
Set screw fittings like the Steel City TC series are dry-location fittings. The steel body with zinc plating gives you corrosion resistance for normal indoor commercial and industrial runs, but for wet or damp locations, outdoor exposure, or anywhere a raintight connection is required, use a compression (raintight) EMT connector instead.
4) Do I need a separate locknut when I land this EMT connector in a panel or box?
The Steel City set screw EMT connector threads into a knockout and is secured with a locknut on the inside of the enclosure, so confirm you have locknuts on hand in the matching trade size when you order. The set screw side clamps the EMT; the threaded side does the box connection.
5) Will steel set screw connectors keep the conduit run bonded as an equipment ground?
Steel is the body material here, not die cast zinc, and a properly tightened steel set screw connector maintains the metallic continuity of an EMT raceway used as an equipment grounding conductor. The fitting is UL listed under E16592. Tighten the set screw down firmly on the tubing; a loose screw is the usual cause of a failed ground path on an EMT run.
6) How is this EMT connector packaged, per piece or per bag?
The Steel City set screw EMT connectors are sold each, so quantity on the order equals the number of connectors you get. Count your terminations per enclosure rather than assuming a bag quantity.
