    Default Derating Confusion

    9CC being the max, is the CC only the Hot or also the Neutral when taking this into equation.

    I've got 8-9 Hots of 12AWG, and a pair of #10 (G and N) going from a transfer switch back to a panel.
    AND Then, I just came across this derating issue...

    So to be complaint, it looks like instead of the 1" I was planning to run, I should run two 3/4 Back to the Panel and then split the lines from the transfer going back via 2 conduits.
