Steel City TC111US – Frequently Asked Questions
1) What trade sizes does the Steel City TC111 series EMT compression connector come in?
Nine trade sizes, from 1/2 inch up to 4 inch: 1/2 (TC111US), 3/4 (TC112US), 1-1/4 (TC114US), 1-1/2 (TC115US), 2 (TC116US), 2-1/2 (TC117US), 3 (TC118US), 3-1/2 (TC119US) and 4 inch (TC1110US). Order the size that matches your EMT trade size, not the conduit's measured outside diameter.
2) Will a Steel City compression connector work with rigid conduit or flexible metal conduit?
No. The TC111 series is built for electrical metallic tubing (EMT) only. Rigid and IMC use threaded couplings or threadless rigid fittings, and flexible metal conduit needs an FMC connector. Matching the fitting to the raceway type is what keeps the ground path and the inspection clean.
3) Should I use a compression EMT connector or a set screw connector?
Compression connectors like the Steel City TC111 series clamp the tubing with a gland nut and ferrule, which gives a tighter mechanical grip and is what most inspectors expect in damp or exposed locations. Set screw connectors are faster and cheaper but are generally limited to dry indoor work. If the run is outdoors, in a garage, or anywhere it can get wet, compression is the one to buy.
4) What material and finish are these EMT connectors, and will they hold up in a damp mechanical room?
Steel body with a zinc plated finish. Zinc plating gives ordinary corrosion resistance for indoor and damp interior work such as mechanical rooms and parking structures. For direct salt spray or corrosive process areas, a die cast or coated fitting is a better choice.
5) Are Steel City TC111 series EMT connectors made in the USA?
Yes, the US series connectors are manufactured in the United States, which matters on federally funded and Buy American specified jobs where domestic fittings are required.
6) Are these EMT compression connectors sold individually or by the box?
They're sold each, so you can buy the exact count you need for a panel change or a short run rather than a full carton. Mixed sizes can be ordered on the same job without committing to box quantities in each size.
7) Do these connectors come with a locknut for the enclosure knockout?
A compression connector of this type threads into the box knockout and is secured with a locknut on the inside. Order locknuts in the matching trade size if you don't already have them on the truck, since the connector is sold as a single piece each.
