Meyers hubs required where

[arnettda]

Can someone point me in the right direction on where in the code I can read about where I need to use a Meyers hub or sealing lock nuts if allowed when entering the side or top of a 3R panel?
Thank You.

If it is a article 314 box, the wording is a bit different. I am not sure exactly where wet location fittings would be required?

ETA 314.15 is the section. I guess everywhere except the bottom is the way I read it.

If you want to follow listing, I believe both meyers hubs as well as sealing locknuts are only listed for RMC/IMC, other raceways you are supposed to use appropriate fitting. That said most liquidtight flex connectors are fine but raintight EMT fittings are useless for sealing against the enclosure wall and I use meyers hub with the RT fitting threaded into it most of the time anyway even though it isn't listed for such.

For Article 312 installations a connection rated for wet locations is required when the entry is above live parts. For boxes in Article 314 all sides require a connection that is rated for wet locations when the box is installed in a wet location.
