Generators operating at alttitude require deration IAW with manufacturers specs. For sake of argument let's say deration is 10% for every thousand feet. In my case I am being asked to provide spot-generation at 5000' altitiude. So a load that requires 200KW must be sourced with a 400KW generator. If I follow 445.13 I will be required to run parallel runs of 1250mcm to a 1200A breaker (Assuming direct burial 90c 4c cable). But all I really need is a 600A Panel and parallel runs of 350mcm. It seems ridiculous to have to follow this rule in the situation described. It seems a complete waste in equipment and cabling cost. Any thoughts on this?
