Wire size?

[RDT]

Parallel 2/0 thhn copper . You can reduce the neutral 1 size with no
problem unless the power co. won't let you . 2-2" pvc runs with
2-2/0 1- 1/0 1-#4 each run . Terminate in a gutter at the house

Big aluminum is hard to work with once you get it into breaker box. I used it at the deer camp to power the skinning shed and it was not much fun. I used copper to run new service to to the cabin.

I would like to because the power company will sell it at cost which is $2/ft for all 3 wires. I just am not 100% sure if it would handle the load..

How close the shop going to be to the meter and house? Why not run a 200 amp service to the house and then a 125 amp service to the shop separately? It may end up being a tad bit more work running 2 runs of conduit but it should save you money in the long run not having to buy 500mcm copper conductors and then trying to pull it.

Can't you share the 200 amp service with the house? You would have to use A LOT of stuff at the same time to need even the 200 amps. Unless you are going to run multiple welders at the same time, that is a lot of juice.

If its sized correctly it will work just fine. The building I'm currently in has a 32meg service and all the feeders are aluminum.

You would be much better off setting your meter base closer to the house. My co-op will do the first 400' of overhead for free.

Wire big enough for that much power and that distance gets expensive real quick.
