This would be where Scott W is going with his message.
It would work, but it sure looks suckee!!! [in my mind, that is].
Just my opinion only! Please be kind in flamed responses [Linked Image] just tossing out some ideas and stuff to discuss.

Scott,
If you have a handbook, 225-7 has a good explanation of using a single neutral sized for the maximum unbalanced possible. ie. If you run (6) 20 a. ckts, off a single phase panel (3 each bus) you could run a neutral sized for 60 a.
Maybe it would help in keeping the mess minimal if running all ckts. through a lighting contactor. Anyone ever do this?
