Brain block and too lazy to look right now (sorry). Now I know NM is not rated for 'WET' location,but ok for Damp. I also understand anything in conduit under ground is 'wet'.
So to the point: IF I run NM across an open ceiling (not allowed above a drop ceiling),poke thru the out side wall with PVC,LB down into a bell box with a WR GFCI and an 'in use' cover.
