125 amp sub panel.

Hello friends looking to make sure I haven't missed anything. I plan to run a 2" pvc conduit with 1/0 conductors for the approximately 100-150ft to the sub panel. The conduit will be 24" deep and sch 40. I know that the neutral and ground are split at the sub panel and I will be connecting the existing ufer ground. This will be to power multiple equipment in my work shop.

You will need 4 wires in your feeder as well as grounding and a means of disconnect at the outbuilding.

Ok, perfect. I don't think I can run a 125 amp main in the sub panel with a 125 amp breaker in the main panel. What do you suggest?

The breaker in the main panel protects the wiring and everything after it. The main breaker in the sub panel is only there as a main disconnect means. It can be the same size as the main panel breaker. Many times it's larger than the main panel breaker.
