I did the exact same copper from main to sub and copper from sub to charge pro box. I used 2/0, as I had it left over from something else. Probably overkill, but no issues at all!!!I used 100% copper to my subpanel and 100% copper to my FCSP.
I have no issues.
That's all I know. I do like that "I have no issues" and would do it again.
