Is it allowed to run NM wire in PVC pipe under an outdoor porch?

Question

I would like to know if it's allowed to run 10/3 Romex in 3/4 inch PVC pipe for 15 ft. outside under the floor of an open porch to be wired to a 30A power outlet for a portable 6500 watt generator.

No. Nonmetallic sheathed cable is not allowed in wet locations. NEC considers outdoor conduit a wet location.

You'll have to use THWN conductors, or other conductors/cables rated for wet locations.

If you use THWN conductors, you'll be able to fit 7 conductors through 3/4" Schedule 80 PVC (Table C.9), or 9 conductors through 3/4" Schedule 40 PVC (Table C.10).
