You must meet all expected source output potentials within the design and operating limits, as long as the distribution panel and connected wiring is rated for the max output of the protected source then you are good. A 200 ATS connected to a 10 kW genny does not require 2/0 as it will never meet that rating. Just remember its whatever the max output can be plus your margin.
