Can I run Romex through PVC conduit underground?

Question

Can I run Romex through PVC conduit underground?
I am running power to a small shed 130" away from the house undergroung in PVC. I found that buying stranded wire is more expensive than solid romex at 10/2. I'm not pulling it through so that won't be an issue.
I just want to know if there should be any problems with that or should I just use seperate stranded wire?

I am planning on:
Get underground romex or run it through grey electrical pvc

I am only going to run a 15 amp subpanel to supply power to two small flourecent fixtures and one outlet for a radio or just use something small. Can I use 12 gauage or should I just stick with 10.

I know code is 18" below ground with a loactor ribbon above it. What about the wire and conduit, what does the code say for that?

Answer 1

you can run romex through pvc pipe no problem. But at 130 feet thats a long run you will have voltage drop. You would only be able to run less than 24 amps. If all you are going to use is a light or a single outlet, thats fine. But if you are needing to run more than that you need to run 3 number 8's with a # 10 for ground.

Underground Conduit

Romex In Conduit

Answer 5

Actually, it s OK for underground use as long as it s inside conduit. UF (underground feeder) can be direct-buried. Ditto to the above, though, Romex is a royal pain to pull through conduit; i did a 50-foot run and just primed each piece of conduit, fed the wire through piece by piece as i laid the conduit and then cemented and joined each section. The Romex likes to bind inside the conduit, and pushing 4 inches at a time gets old really quick.

Hire a qualified professional electrician and an apprentice to do it. They need to make a living. They will probably use the finger from a rubber glove tied to the end of the string to pull it through. Another way is use a 200' 1/2 mouse that is shot through the conduit with compressed air. If the joints in the conduit are loose then air will leak and none of these methods will work. I repeat hire an electrician.

You can run the romex cable through the PVC. I would definitely run the 12 guage wire. It will be in a yellow sheathing which helps identify it. If you say that you are only running the two lights and an outlet, you will be fine. You will also need a 20 amp breaker for the panel inside your house. You can also run UF cable, which is ideal for direct burial. It will probably save you money on the PVC, especially if you are running through your yard and not under anything, like a driveway of a heavily trafficed area. Good Luck and I hope everything goes great!

Answer 8

You can do anything you want but I believe the reason for not doing it is because Romex is rated to include heat dissipation based on open air wiring not inside conduit. Besides the cost is cheaper to run ordinary wire up to the maximum 'fill' of the conduit.

Answer 9

Yes you can run romex (nm) through pvc conduit underground to your shed. At 130 feet I would recommend the #10 you mentioned, to limit the voltage drop.

Answer 10

As you've pointed out... Underground Romex is the stuff you will want.

DO make sure that when you run it, you mark WHERE !!

My brother bought his ranch 5 years ago, and we've had a DELIGHTFUL time tracking Underground Romex running out to the Barn and Green houses... as well as all the irrigation.

Good Luck !!
