Wiring Outbuilding

Please help. I want to put a panel in my outbuilding. I need know what size wire to run and what size panel. Prefer to use direct burial wire. The building is 200 feet away from home. The panel needs to hold at least (2) 220 amp circuits for an air compressor and a welder and (3) 15-20 amp circuits.

It would help greatly to know the load for the compressor and welder as well as the duty cycle of the welder.

Welcome to the forums.

You'll probably need a 240v 20A breaker for an air compressor.
Another 240v 30A breaker for the welder.
Plus at least three single pole breakers for misc.

I would use a 100A 120/240v 16 circuit panel with 100A main breaker.
You'll also need a two pole 100A breaker in your house panel to feed the sub panel.

You would probably use 2/2/2/4 quadplex underground cable... like what is used for a motorhome.
