Thomas & Betts 5120 – Frequently Asked Questions
1) What trade sizes does the Thomas & Betts EMT coupling come in?
Four trade sizes: 1/2 inch (part 5120), 1 inch (5320), 1-1/2 inch (5520), and 2 inch. Match the coupling size to the EMT trade size you are joining, not to the outside diameter of the tubing.
2) Can I use this EMT coupling on rigid conduit or IMC?
No. These are EMT fittings, sized and made to join electrical metallic tubing. Rigid and IMC are threaded and take threaded couplings or a threaded-to-EMT combination coupling instead.
3) Do I need a coupling or a connector to tie EMT into a panel or box?
A coupling joins two lengths of EMT to each other. To terminate EMT at a box, panel, or enclosure you need an EMT connector, not a coupling. Order both if you are running new conduit: couplings for the mid-run joints and connectors at every box.
4) Is the T&B 5120 EMT coupling steel or die-cast zinc?
Steel. The T&B EMT couplings in the 5120 family are steel bodied, which is what most commercial and institutional specs call for on EMT runs rather than die-cast.
5) I need to standardize EMT fittings across a building. Can I order the same T&B coupling in mixed sizes?
Yes. The same steel T&B coupling design runs 1/2 inch through 2 inch, so branch circuit runs at 1/2 inch and feeder runs at 1-1/2 or 2 inch all use the same fitting family. Useful if you are keeping one line item on the MRO shelf across several trade sizes.
6) Is anything else needed to install the T&B EMT coupling?
Nothing beyond a screwdriver or wrench for the fitting itself. Cut and ream the tubing ends, slide them into the coupling from both sides so they butt in the middle, and tighten. Straps or hangers to support the run are separate items.
