So a 20Kw Generator is 83A @ 240v, a 8000w Generator is 33A @ 240v. I take it these amp ratings should be the breaker size for the Generator. So a 30A generator panel for an 8000w generator. Does the 80% rule apply to generators as well? I heard its 90%.

A Generac 14KW has a 60 amp breaker installed in it. 14KW = 58.33A @ 240v.

Panel has to be rated at least what the generator can output. Often times more. It is cheaper to make just a couple of different rated panels and mass produce them than to make many different size panels in small quantities.

I've seen configurations where there's a 7000w-8000w generator feeding into a 60A emergency sub panel, I take it the 30A breaker built into these generators is what protects the generator and it doesn't matter that there's a 60A in the panel. The 60A is only acting as a switch at that point and working as a 60A breaker when in the utility position?

Hope I'm making myself clear lol
