Now I want a generator - Wireway Sizing

[kwired]

kwired, did you use the second column of 312.6(a) for that figure? Meaning two conductors per termination and if so you chose that because the feeder conductor appears that it would have two taps coming off it?

Well, I think that is probably what I did when I came up with that response. If only one wire per terminal I see that it could be up to 500 kcmil and still work in the 6 inch gutter, although that may not be all that easy to install.
