And electricians out there

Honestly though, you have no reason to trust my advice. I'm just internet guy 100222020. Get a second opinion if you can.

You should bury the line in some 1" schedule 80 PVC conduit, at least 18" to the top of the PVC. Pull 3 lines (Hot, Neutral and Ground) of #10 THHN stranded and call it a day.

I have the wire left over from the pull to the well house by previous owner's electrician 15 years ago. I also have the pvc I got free last year! I have to rent a small trencher as this place is full of large oak and pine, but now I have a plan!
We have about 8 Boer goat nannies that will kid in Jan. so I have to get 'er done! Record cold here today, hopefully in Jan it will be normal temps!!!! not a low of 23 and high of 40 with 20 mph wind!!!
Thanks for the input. I can actually do math but I admit I am dyslexic, I see so much upside down, inside out, and backwards!!!!
