If the wire is exposed, then it must be in conduit (or some protective enclosure). IOW wire on a house side must be in conduit. Someone could touch it. Some moving items could strike it. Wire inside the wall cannot be touched - is protected. No conduit required.
Wires through or between floor joists beneath the house are considered not exposed. Considered protected from human contact. No conduit necessary as long as it runs along joists or on the plate that joists sit on.
I cannot say enough about anchoring a weather tight box so that no moisture gets behind it. Whenever possible, I cut the plywood and mount that box partially in the wall - mounted firmly to a 2x4 nailed between two studs. Just mounting the box attached to plywood by screws is (by my standards) woefully insufficient. It must be firmly anchored (if possible) to wall studs due to the 'violence' imposed by plugs - especially 30 amp plugs.
I believe this outlet must be powered by a GFCI breaker. I don't know of any exception.
