RE: OT :cable amp ratings - answers to wrong questions

That's because in those larger sizes it's an actual measure of area 
in circular mils or in this case thousands of circular mils (kcmils). 
One of those technical pdfs from General Cable that were mentioned a 
couple of days ago was a conversion chart, and it says a circular mil 
= 7.854x10^-7 sqare inches. (1 mil=.0001 in. and it looks like a 
circle 1 mil in dia. is 1 cmil in area.)
