Wire for main panel

Hopefully he means footing. Slabs can be "insulated" from wet earth.

It’s in the footing, but good point. I did insulate under the entire slab, but not under the footing.

Not if you're able to use the reduced neutral

What does a reduced neutral have to do with grd conductor size?

Grd size depends on ocp value, conductor material and upsizing for vd.

Too bad he wont be doing a load calc to know what his load will be

For one, NEC load calcs are complicated. Two, my load is whatever tool I’m using at the time plus some LED lights. I’m not over complicating this if I can help it. I’m not reducing my wire size below 4/0 so I don’t see the point. I have a shop to keep building.

Load calcs arent complicated

Hell theres even spread sheets available for free to calc it for you

Yeah I had 4/0,4/0,2/0,4 MHF on the brain but used xhhw to give him the cart. Disregard my reason, but #4 is still correct.
