Romex IN conduit for protection

[Ramper]

I am working to complete my shop (30x40 pole building). I have successfully run some out outlets in the ceiling (not up yet so in the rafters).

I want to add some outlets to some shelving that was installed when we bought the property. The shelving was 4 feet deep across the back wall and half of one side. There were two shelves (one about 4 feet up and one about 8 feet). I took some of the bottom selves out to make some more floor space (I gain about 24 feet by four feet). I want to add some outlets to the posts of the shelves I took out. I plan to run romex in the wall to to the posts, but would like to protect the outlets and wire by using metal conduit and boxes.

Can I use the conduit to protect the romex? Would PVC be OK or should I use metal. I plan to run four outlets (two plugs each) on their own GFCI protected circuit (I will use a GFCI for the 1st outlet)

Some where I read that Romex in conduit, is regarded as a damp environment and requires the direct burial type of Romex.

I just have the yellow (12 gauge) romex. Did I use the wrong stuff of the ceiling outlets?

this is only when installed outside. inside it's fine

MC cable might work for you....no need for the added conduit

I have the romex (purchased clearance), so I hope to use that.

Metal Clad has the same requirements for physical protection as NM cable.

It sounds as if you are wanting to just run it up the posts to protect the wire, and not run a complete conduit system. Romex is very difficult to pull in conduit, so if you want to fully run conduit, get THHN wire, if you just want to run up the posts to the rafters and stop, yes, its legit and a good thing to do. Plastic or metal depends on the boxes you use. Inside I would be using metal (EMT) and steel boxes. They make a conduit end to clamp the wire where it exits the EMT, which makes for a neater installation.

If using EMT you can also use a press on EMT plastic bushing on the end where the Romex enters. You need to staple the Romex within 12" of the conduit end.
