ECN Forum Forums Code Related Discussion NEC & other Code issues NM in buried PVC Conduit

I know NEC explicitely allows NM through SCH 80 conduit, but doesn't mention SCH 40. Can I run NM through SCH 40 conduit? What if it's #12 NM on a 20A breaker (120V) and GFIC protected?

This will be buried and will pass through concrete.
