not sure how big to make it.
Basically just running power tools. I have a table saw which probably draws the most amperage and I may put an outlet for that on a separate circuit.
I'm barely using anything in the house right now, but I want to do this in such a way as to have plenty of options down the road for both places (maybe someday someone will want to charge an electric car out there, for example?).
Run large PVC conduit, it's cheap, and make an upgrade very easy. I don't know what an electric car would to charge it up, but I'd imagine it could use a hefty amount of power if it was going to charge up quickly.
That in mind, I'd run 1-1/4" or 1-1/2" PVC (buried).
For now a run of 8 gage thhn in conduit for 50a service would likely be more than enough.
