Romex in PVC

[blytk]

I'am replacing some 15amp (14-2) recepticales with some 20amp (12-2) in the garage attached to the house. There is two dedicated circuits, one for a fridge and one for a large freezer. Right now it is just a single circuit of 14-2. There is a section that passes through an interior wall in the house to the garage then along the wall in the garage (up 8' in 1/2"pvc) to a junction box into EMT to the plugs. My question is can I run 2 circuits of romex 12-2 in that 1/2" PVC? Comes from the panel as romex through the PVC to the junction box to EMT. The pvc is just for looks and a little protection in the garage (open at both ends, and not wet conditions)

Not sure it will physically fit.

You will never get two runs of it in a 1/2" PVC conduit.

It will be tight, could work if you use some soap but I would strip the jacket off. It might pull if its a straight run and not too far.

Generally the wire used in Romex is not marked on the individual wires, only on the Romex jacket. Code does not allow unmarked or un-identified wire to be used, you would be violating the UL listing approvals for the Romex to do this (yes, I know, we all do this for short pigtails and jumpers, but I cannot imagine doing this with several feet of wire.

I tried a run of 4' with a scrap piece of 1/2" pvc and it worked good no problem pulling it. This is a straight run no bends or anything. Just what to make sure it is legal and won't cause any problems.

Agreed, and not going to get 2-12/2 NM cables in 1/2" conduit, 3/4" will be needed.

use 12-3 & ground.will be better.or just a little larger 12-2-2 & ground.

Is the refridgerator and freezer in the same pvc that you mention? Or is the recepticle circuit in a seperate pvc? Although you may be able to fit two pieces of Romex in the 1/2 inch PVC, I would have to question the conductor fill. I belive you are not to exceed 40% of the internal area of the conduit.

can you do it? maybe. will it work? probably. is it legal? no.

I have a question about this, same situation. Can I do 2 runs of 6-2 through 1" PVC legally?

I had a look at several CEC rules that may apply to this and came away with a lot more questions than answers,so in my opinion,no it is not likely permissable, especially if it is indeed 1/2" PVC.Rule 12-1106-PVC conduit must be protected where exposed to mechanical damage,so
one could interpret that as one can't really use it to protect NMD90!

I would have to do the calculation but i am reasonably sure that you are over the wire fill limit and the cable would have to be listed for installation in conduit.

There is no wire fill limit if the conduit is used for physical protection and meets the requirements of Ch. 9 Tables, Note 1.

the cable would have to be listed for installation in conduit.

Which code article requires Romex to be listed for use in conduit?
