Default Transitioning from in-wall wiring to EMT (conduit)...

He's saying that romex does not have to be stripped inside of any conduit,,
"it's an urban myth"

They make direct EMT-to-Romex fittings. I have only ever seen them in
1/2", to small Romex; the Romex clamp (officially known as NM cable,
BTW) is 3/8", and suitable for 14-2, 12-2, and maybe even for 14-3 and
12-3. The next large solution has already been mentioned: Use an
EMT-to-threaded connector, followed by a threaded coupling, followed
by a clamp for the Romex.


According to NEC, what is the smallest size EMT that you can run 14-2
Romex through?

To make sure you hide all the cable in the wall, drill a hole deep
enough that the first 1/2" or 1" of the EMT is hidden in the wall. By
the way, drywalling around the EMT will be no fun, hard to get it nice
and smooth.

There is one more annoying little issue: the EMT has to be grounded,
at the minimum by being connected to a grounded metal box on at least
one end. If you use an EMT-to-NM fitting, or the method with the
threaded coupling, there is no place to attach the ground, so you
better hope you can ground from the other end. Also, the NEC allows
small sections of unstripped Romex in conduit only. If you have a
long run in conduit, you shall strip the outer jacket off; the
conductors used inside the Romex are perfectly happy to continue on
inside the conduit.


Are you saying that NEC does not allow Romex to run up through EMT but
needs to be stripped first?

I am pretty sure our electrician wired the basement with exposed Romex
running
along the ceiling and then dropping down through EMT to get to the
wall outlets.

Can you clarify please?
