Am i sizing the wire for a used cnc machine right?

[dftmaint]

We got a used cnc lathe in and i just want to make sure i am sizing the wire correctly.

Nameplate says 32KVA 3 Phase 220V

It has a 150A mccb, i don't size the wire to this, right?

I size the wire using the nameplate KVAx1000 / 220x1.73.

32000/380.6 = 84amps

Using the 75 degree c column i could use 4awg thhn rated 85amps

We have some 2awg thhn laying around so i will probaly use that but could i use 4awg?

Is there anything else i need to consider?

Thanks for any input.
