NM cable is not rated to be inside a conduit system. I ran my pool pump

12-2 NM for a month while I got the new conduit run. As long as the 6
is
enough for the load and distance.



I'm just curious, and not meaning to start a flame war here, but where in
the code does it prohibit romex to be in conduit. I remember threads in
the past where this was discussed and I can't remember what the outcome
was.

Greetings,

a) Don't matter what the NEC says if your local inspector shoots it
down.

b) As I understand it you can run Romex in conduit. I have run 100's
of Romex wires inside conduit for additional physical protection. You
just can't run it inside a "conduit system" which means conduit
attached to a box at both ends or for extended lengths. You also must
provide a large enough conduit to prevent overheating. I try to use
3/4" for a single 12-2 or 12-3 NM cable to be on the safe side.

c) Today I ran 2 12-2 NM's inside a single 1/2" piece of EMT for 8 feet
with the yellow jacket stripped except for a few inches at the end for
a clamp. It's safe but you might have someone complain because the
wires inside NM don't have THHN written on them even though they are
rated at 90-105C.

Hope this helps,
William

Thanks William. Your letter (a) is right on! I tell ya, trying to figure
out all the code requirements is harder than the actual wiring of just about
anything! I just ran some circuits in my garage and I spent more time
thumbing through the code book looking for stuff than I did doing the actual
work. Probably why Electrician's charge so much!
