Feeder size changes in NEC 2008?
Hi guys:
Did the NEC 2008 change feeder sizes for "most" ampacities or only for 100A?
I don't have ready access to the 2008 code, so am asking the experts.
Per the NEC 2008, what is the correct feeder sizes for MLOs of 125A and 200A.
I know the old code said 4/0 AL was OK for 200A, but not sure about the new code.

AL: 125A = #1/0, 200A = 250 kcmil
CU: 125A = #1, 200A = #3/0
Now if these subpanel(s) carry the full load of the dwelling, they still qualify for 310.15b6 which is:
AL: 125A = #1/0, 200A = #4/0
CU: 125A = #2, 200A = #2/0
