Running power from garage to shed

I am running a 20 Amp dedicated circuit to the shed in rigid conduit 6+" deep. I have a weatherproof mounted to the LB conduit body outside of the garage.

I ran 12ga THWN wires from the shed to the LB conduit body Can indoor Romex be in the LB conduit body on the outside of the garage Or what are my options? I am going to use romex from the panel in the garage.

You can use NM-b from the LB to inside.
There cannot be any NM-b used outside.... in conduit or not in conduit.

Best to run separate conductors but if you want to run a cable.... use #12 UF.

LBs are quite small and only some are allowed to splice in. I would recommend using an outdoor-rated metal box instead of an LB. Another option is to run an RMC nipple into the building and connect it to a 4x4" steel box. You are also required to bond the ground to the steel conduit if it is not run continuously between pull points.

Isn't the requirement for buried conduit 18" deep?
