That's the part that is throwing me off. If I have 3 times the circular
mil and compare that to a single conductor of similar circular mil, how
do I have 3 times the ampacity? These are very different numbers.
Example: 1/0 @ 90c is 170 amps x 3 = 510 amps. 510A is what a conductor
just over 750 AWG will carry. The circular mils of 3 1/0 cables is only
325,050 or a 325 AWG cable which would be rated at about 330 amps.
So, is it 510 amps (3x the ampacity) or 330 amps (3x circular mil)? And,
more importantly, why?

I am sorry. Bad fingers. Three times the ampacity under the same

OK, let's use 1/0 for the example. 108,350 x 3 = 325,050. Do I now
have a cable between 300 and 350 AWG?
Thank you,
Larry
