Steel City TC125SC-1 – Frequently Asked Questions
1) Will the Steel City TC125SC-1 connector work with 1-1/2 inch EMT?
That's exactly what it's built for. The TC125SC-1 is a 1-1/2 inch set screw connector for EMT (electrical metallic tubing). Slide the tubing into the connector body, tighten the set screw against the tubing wall, and the threaded end goes through the box knockout with the locknut. It won't work on rigid or IMC conduit, which is threaded, and it won't work on flex or MC cable - those need their own fitting types.
2) Is the TC125SC-1 EMT connector UL listed?
Yes. The Steel City TC125SC-1 carries UL file E16592 and CSA certification 12798000, so it satisfies inspectors looking for listed fittings on an EMT run in commercial or institutional work.
3) Should I use a set screw or a compression EMT connector on this job?
Set screw fittings like the TC125SC-1 are for dry indoor locations - a set screw clamps the tubing but the joint isn't sealed. If the run is outdoors, in a wet or damp location, or anywhere a raintight fitting is specified, a compression (gland nut) connector is the one to order instead. For interior commercial work above a ceiling or on exposed block wall, the set screw type is the standard choice and it installs faster.
4) What is the Steel City TC125SC-1 connector made of, and will it rust in a parking garage?
Steel body with a zinc plated finish, silver in appearance. Zinc plating handles normal interior and covered exposure, but it isn't a substitute for a listed wet-location fitting. On an open deck, a wash-down area, or anywhere subject to standing moisture, specify a raintight compression fitting rather than a set screw connector.
5) Does the TC125SC-1 come with a locknut, or do I order that separately?
Steel City sells the TC125SC-1 individually, each. A set screw connector ships as the connector body with its set screw and the locknut for the box side - what it does not include is the bushing. On 1-1/2 inch EMT you're pulling conductors large enough that an insulated throat or a separate insulating bushing is usually wanted, so add those to the order if the spec calls for them.
6) Can I use the TC125SC-1 to connect 1-1/2 inch EMT to a panel or junction box knockout?
Yes - that's the standard application. The threaded end of the TC125SC-1 passes through a 1-1/2 inch knockout and the locknut draws it tight from inside the enclosure, while the set screw end grips the tubing. The knockout has to be the matching 1-1/2 inch trade size; a reducing washer set is needed if the enclosure only has a larger opening.
7) What is the exact part number for a Steel City 1-1/2 inch EMT set screw connector?
TC125SC-1 is the Steel City manufacturer part number for the 1-1/2 inch EMT set screw connector, steel with zinc plating. That's the number to quote or cross-reference when matching what's already installed on a job.
