NEC 314.15 requires compression rigid fittings to be listed for wet locations. Any leads on 2" wet location compression rigid fittings? I did a search and didn't find anything. I'm seeing recent projects that are passing inspection with the concrete type fittings. It's also surprising that quite a few supply houses I've been to still don't even carry wet location fittings for EMT or rigid. Is this being enforced in your area?
I'll see what I can find. I knew when I was coming up in the trade, there weren't any listed coupling. A few years ago I do believe Thomas and betts had one. It was gold in color to easily identify it as the listed fitting
U/L started listing them around 2002 but, unfortunately the color coding thing was not specified so the manufacturers trademarked their own colors. Some are gold, some are blue and some are silver and stamped "wet location". Your supply house should have them. I even see them at Home Depot.
Started using the wet location EMT fittings as soon as they came available. I figured it wasn't worth risking having to repull wire even though most of the contractors in the area were still using concrete type fittings. Some still are and are getting away with it. The price has come down so it's logical to use the correct fittings. Rigid wet location fittings are a different animal. I'm not seeing anything available.
Yep, I was referring to compression fittings as concrete type. Looks like the ericsson 3-part couplings are going to be the closest thing to water resistant. Most likely the wet location listing is more aimed at protecting the equipment rather than to protecting waterproof conductors from moisture. I have a rigid 700 threader but avoid threading as much as possible. Too messy!
I've never understood wet location compression fittings. For one, we are using THWN which is rated for wet locations. Two, once the rain tight fittings are installed now there is no way for the condensation to drain out. I don't see a lot of rain getting into conduit installed above grade, but I do see rain tight fittings making sure whatever moisture gets in stays in.
