Yes. There’s a 50, 30,and 20amp pre-wired receptacle base/box put together for RV use.

Pulling it through 2 90’s is tough. 3 90’s is not impossible, but run the risk of straining the wire and possibly compromising the insulation. A megger will verify after the pull.

Feeling pretty confident it won’t be too hard once I got the wire ( 6/3 UF-B) and saw it passed fairly easy in some 1,25” PVC. I think I’ll be able to pull a length of conduit down the wire and then glue it together once in place. The 2 - 90’s will be at each end… again put in place over the wire before glueing. Just need some time to do it now. Weather and holidays not helping.

Normal max fill by code is 40%. Sounds like it’s pretty empty, but individual conductors at 40% is really full . More than one 90 bend and it’s a PITA. As a cable assembly the smaller wires are stacked side by side where your cable may be relatively round or flat, depending on the manufacturer. If in doubt and if you can you can run it through the 10’ sections and then glue them together. The UF jacket is the required cable protection and the PVC is just overkill.

If you have sized the cable correctly, I.e.distance vs load, overheating shouldn’t be a concern.

I would be tempted to just bury the UF and dump an inch layer of dry concrete on top of it. I'm always doing the extra and im not sure it's ever made a difference.

Most areas that have rocky soil surround the cable with sand. Rocks, pressure, vibration and frost/ice movement are the main issues. Just your luck that armadillos love the taste of your thermo plastic.

If you sift your bedding and fill for rocks you should be OK. If you ever want to increase the size of your feeder, the PVC would be a nice thing. Just don’t stretch it tight to allow for expansion. Plastic grows and shrinks from temp. Like crazy. There’s a bulkhead by us with PVC feeds for the lighting. In the winter it’s straight and level. In the summer it sags like crazy. Good luck whatever you decide.
