Is it ok to run 2-12/2 romex cables in a 3/4 pvc conduit? Will there be a heat problem?

Not supposed to run romex in conduit. Except a short run too protect the romex on a cement wall.

Someone will be along to give the NEC code on it and a more technical reason why not!

fitter457 03-13-2013 06:24 PM

What is the reason why your not suppose to? Are there any dangers?

The romex can not be installed in a damp or wet location, so if the conduit is inside you are fine.

It will be inside a building that makes cheese. It will be humid. Think it will be ok.

How long of a run are we talking about? I believe if there are so many wires in a conduit you have to do some derating because of heat. Hopefully someone will come along with specifics.

its fine, the only issue that arises is conduit fill.

If it is a long pull, I might step up to 1" just to make it easier.

Or just use a different wiring method since I spent the time to install the conduit to begin with... :-\

Depending on the buildings classification NM may not be legal in conduit or otherwise.

Since this is a DIY site, I hope that it is Residential, and a non issue...
