I saw this post, I know it's an older post but I have a question. Virginia just recently adopted the 2008 NEC and I have been trying to catch up with the updates. I recently came across a situation where I want to route multiple 2P circuits in a single conduit, 2 phase wires & a ground, no neutral. How does the changes to article 210.4 effect this situation, or does this not apply when no neutral is present? Any insight would be great.
