@MichRR714 posted:My Siemens 200 amp service at home has the bus bar such that every other circuit moving up or down is on the same service leg. Fortunately I remembered this when pulling the circuits when I finished my basement. I guess every situation has to be looked at to evaluate what is going on. Was good thinking on your part to figure it out.
Yes, for standard 2 phase power, every other space on the same side up or down is the same phase, if you go to the other side, you have to go up or down one space first to get the correct phase, then it's the same like the first side, every other space up or down is the same phase. (The space directly across from the first space is the other phase) IMO, easier in the long run to make sure all your circuits for your layout are on the same phase, so no problems if you happen to unplug something while working on the layout and accidentally plug it into a different outlet on a different phase.
