Question About Box Supporting 314.23 (e)

CNC

in article 314.23 (E) its states

raceways supported enclosures without devices need to have threaded bodies, OR hubs identified for this purpose. Now a NEMA box within the correct size, supported by 2 emt raceways, with rain tight connectors do it? WHere do i find hubs identified for it.

We have to fix a bunch of boxs, that got stubbed up to an attic, and then a junction box got added, and MC was run directly out of it. Most of the boxs are only stubbed up 10 or so inches, with one pipe. Its a 16 inch center wood framed attic so there isnt much to mount to. i guess ill have to mount them on uni strut, any quick tips?

Quick tips?

Yes, forget about the unistrut - that's for industrial type stuff and looks lousy in a home. Use wood (perhaps plywood or whatever works) and fasten it across the floor joists. Mount j-boxes to that. I hope I understood your question.

EMT cannot be used to support an enclosure. Only rigid or IMC. The only listed hubs I know of are Meyers hubs and will not work for this installation. Hope this helps!!

You don't.

Lets look at the NEC:
You can't thread EMT, so it will never be "wrenchtight".

Even the exception doesn't help...
A box is not a conduit body.


A wood frame to act as support is the easiest choice.
