Rigid EMT from under floor or through drywall

Long time reader, first time poster.

I am currently in the process of a remodel and am wondering if anyone here has any experience with this.

Ideally I am looking for a clean transition from NM which will be run under the sub floor in a few locations and also run above drywall in a few others to transition to Rigid EMT. This would be for the purpose of overhead lights and switch legs and also for wall mounted receptacles.

I know for the ceiling I could easily use an extension ring and branch off of that however I was hoping for something cleaner. The wall mount receptacles are to be mounted on brick.

Any suggestions?

Set a junction box.

I'm not aware of any listed products to change-over from romex to EMT.

Because you cannot strip the outer sheath off the the NM, the EMT is only a sleeve. Slide one of these on each end of the EMT.

Thanks for the replies so far!

Not to come off as dense but if I understand this properly it's suggested I use a coupling such as what Philly Master linked to and to use the insulating bushings Jim Port linked to bring me to next box where I could switch from NM to THHN?

Just a thought...any reason for not using PVC? It won't rust.

ddawg16- For aesthetic reasons I'd like to keep with rigid emt, it will work well with the exposed brick in the space.

You could use a slip on bushing at the far end of the sleeve and use an EMYT connector at the box end. Make your transition in the box.
