Long story, I will try and make it brief. This project needs to be by the book, it will be inspected (permit already pulled).
Running 425' to my shop from the house. Using 4/0-4/0-2/0-4 MHF. Was planning on PVC conduit into the ground, then direct burial.
We cut the trench today. Ran into way more brownstone rock than we anticipated for over half the distance. This rock, although soft, breaks into sharp/jagged edges and lots of debris lines the trench. Therefore, looks like I need to run conduit for the distance. (A few inches of sand above and below the cable would work, but we pretty well have the road totally blocked with excavation spoils (80k excavator with 36" bucket was the only thing I had that would break thru the brownstone, trencher and backhoe were futile).
I need to break the cable run in half. That is one heck of a long pull, and I will have over 360 degrees of bends in a single run. I thought I'd use a ground box, but they are $$, and where it would sit catches runoff and it would always be full of water (along with the normal snakes).
What I am thinking is to use a post mounted weatherproof junction box, with the conduit turning up into the box. No splice, just a loop. Much cheaper than a handhole.

I couldn't find an exact pic, but these will give y'all an idea... Mounted on posts and crossbars, like this (right hand drawing):
Sort of like this, but bigger box, bigger conduit, bigger wire:
Most of the wiring path runs down my access road to the shop. Just past the halfway point, it turns off into the woods away from the driveway. If I put the pull box here, it is out of the way and clear of any traffic being able to contact it.
Good solution?? Meet code? (we are under 2017). (I got a couple of other questions for the inspector before I get him out here...but figured I'd do the obvious and ask the Internet first).
