Infinity,
Why 4 sets of 500 kcmil? Four sets of 350 kcmil will do the job.

Don, you're correct. I was for some reason thinking about a common test question, 'how many sets of 500kcmils would you need for a 1200 amp service'? We think well, 400 amp= 1 set, 800 amp= 2 sets, 1200 amp=?, 3 sets, wrong because of 240.4(B) & (C). The answer would be 4 sets. Sorry for the error.
