Re: Wiring shed with 10-3 wire

A few other points to ponder:
NEC 300.5[D][4] PVC conduit installed above ground and exposed to damage must be Schedule 80.
NEC 250.32[A] When the detached garage is served by only one branch circuit a grounding electrode system is not required.
So you do need a grounding rod.[Two circuits].
I too would use the largest PVC possible. Not really a deal breaker in the price difference in PVC diameters. And planning for the future as well.
I would not pull Romex nor even UF cable. While UF is of course permitted per NEC 340.10. Buried PVC is classified as a wet location. I would suggest using THHW cable, suited for dry & wet locations. You will need FOUR cables anyway. Two hots, a neural and a ground cable. Basically the last two will keep the neutral & ground separate. And separate cables would be an easier pull as well.

just sleve the wire with pvc a foot below grade and string the uf in the trench. this will be the cheapes. if you were puttin a 100 amp panel id do it differnt, but your not. this is simple and cheap. The AHJ is deffinetly going beyond what is required, but what do ya do??
