NMB in conduit

I want to run a 20A circuit from one shed to another. Since I have a lot of 12/2 G romex left from another project, I'd like to run it in PVC conduit underground to the second shed. Is this legal?

No can do. NM-b is not rated for wet use. Anything outside...even in conduit... is considered wet.

Thanks Pete. I thought that's what I remembered but wasn't sure. Indoors is ok but not outdoors?

NM is OK in a "normally dry" environment per code. It also requires "protection from damage" which is subjective, but may or may not be OK in your shed depending on the construction and what it's used for. Underground or wet location you'd need UF cable, but also still needs to be protected.

I'm going to get some THWN & run it in PVC conduit. Once it gets inside a box in the shed I'll switch to romex.

That would be a good plan.
