Wiring Question Concerning EMT Conduit Usage
 

Hello:

Regarding the use of EMT tubing in a residence.
Tried to find the answer to the following but couldn't.

Although it probably a lot harder to thread, was wondering if it Is code
permissible to run NM wire in EMT tubing, or must one use individual wires
(individual black, white, and a green Ground) ?

Is THW still the primary choice for residential usage in EMT tubing ?
Or,... ?

Thanks,
B.

I don't know if it's permitted, but I'm curious why you would want to
try it when there is a standard, easy to find, easy to use, inexpensive
alternative.

You don't thread emt, you use fittings. If you want to run cable inside of
tubing its ok as long as the tubing is electrically continuous and if it's
used in a wet location, the cable inside it must be rated accordingly

By 'threading' you mean, pulling cable through the pipe, correct?

Anywhoo - I know that we used to pull NM cable through emt and never
had any inspections fail; but it was a short distance (from washing
machine outlet to top of foundation, in a basement).

THW would be fine.

Thanks for reply.

This would be (specifically) what, please ?

You can use the Grey PVC (rigid non-metalic conduit) or blue "smurf
tub" (electrical non-metalic tubing)

Ah ent, gotta love that stuff, very pretty.

I plan using ent to protect wires from the back of a lighted-medicine
cabinet, and the wall box. It's only 4" jump, so I felt safe to use
it.

as for conduit, I believe the OP asked about cheaper, is ent or rnc
cheaper than emt?

Sorry, I didn't mean to be cryptic. I use THHN/THWN in EMT. It's
single conductor wire available in many sizes and colors. You can put
together whatever combination you need and pull it through the conduit
pretty easily. In fact, if you've used a bender, as opposed to elbow
fittings, you should be able to PUSH a group of wires through a fair
length of EMT without using a snake.

I don't mean to argue; I've had no experience with plastic conduit. But
I think that negotiating the learning curve (play on words intended) of
bender usage has been worth my time. I mostly get it right now, but I
have made some wasted pieces in the past. It didn't take that long to
learn, either. My total experience probably adds up to a hundred or so
bends.

The main advantage to using a bender is the ease of pulling wire
through the resultant conduit path. Whatever extra time I've spent
bending the conduit has been more than offset by the time SAVED not
having to open up every #$%! elbow to get the wires through. That goes
triple for pulling MORE wires through the same conduit at a later date.
