I have found several hundred feet of 8 AWG wire that I would like to
use to bring electricity to my shop that is 200' from my house. At the
moment I use a 3ph propane powered generator but it is expensive to run.

I plan to run the wire through a buried plastic conduit and have enough
wire to be able to have two of each of the power carrying conducters and
two ground conducters.

What will the current capacity be of this setup? (I realize it is
probably not up to code)
