Topaz Lighting 392C – Frequently Asked Questions

1) Can I use a Topaz 392C combination coupling to join EMT to rigid conduit?
That's exactly what the coupling is for. The Topaz combination coupling is built as an EMT-to-rigid transition fitting, so one end takes EMT and the other takes rigid conduit within the same raceway run. If both ends of your run are EMT, you want a straight EMT coupling instead, not this combination fitting.
2) What trade sizes does the Topaz EMT to rigid combination coupling come in?
Two orderable sizes: 3/4 inch (model 392C) and 1 inch (model 393C). Both are same-size transitions, meaning the 3/4 inch part joins 3/4 inch EMT to 3/4 inch rigid, and the 1 inch part does the same at 1 inch. There is no step-up or reducing version, so size the fitting to the conduit you already have on both sides.
3) Can I use the Topaz 392C compression coupling in a wet or outdoor location?
No. This steel combination coupling is an indoor fitting. The zinc plating handles the corrosion you get in mechanical rooms, utility spaces, and general commercial and industrial interiors, but it is not a raintight or wet-location fitting. For an exposed exterior run or a damp location, specify a fitting rated for that environment rather than this one.
4) How many Topaz 392C couplings come in a box?
Pack size is 100 pieces. That is a contractor-quantity carton, worth knowing if you only need a handful for a single panel transition, and worth knowing the other way if you are stocking a truck or a job trailer for a full raceway rough-in.
5) Do I need any tools or extra parts to install the Topaz combination coupling?
The coupling ships complete with its compression nut and re-usable ferrule, so nothing else is required to make the joint beyond a wrench to draw the nut up. The rigid side threads on, so the rigid conduit has to be threaded and reamed before assembly. No adapters, bushings, or locknuts are supplied or needed for the transition itself.
6) Can I take a compression coupling apart and reuse it if I have to move the conduit?
Yes, and that is the practical reason to pick this one. The ferrule is re-usable, so if a run gets repositioned during rough-in or you have to pull the EMT back to correct a measurement, you can loosen the nut and re-make the connection with the same fitting instead of cutting it out.
