Hi:
Can #12 THHN be run through 1' gray PVC Electrical conduit?

If Yes, what is the code fill rate for 1" PVC? ( I believe that 1" EMT
can handle 18 #12 THHN maximum.)

Thanks


Table C10 says 25 #12 THHN will fit is 1" sch 40 PVC rigid nonmetalic
conduit

Thanks. I had also intended to ask if the PVC conduit is permitted for
interior residential applications (this would run up through a chase)

That would likely be a local code issue, it's not something in the NEC.
I doubt you'd have an issue since PVC DWV stacks do the same thing with
the same materials.
