What is the reasoning behind using 2-pole breakers for multiwire branch circuits? I recentlly did a service and they had a sub panel that had to be eliminated. It had 11 circuits, I put a columbia box in the attic and ran 6 3wire cables to it. So now in my new panel these are multiwire branch circuits right? I know you want to put the the circuits on different legs for balance, but marking the panel was a chore (had to lift wires). Also trouble shooting would be the same. Then there was trying to explain to the HO why there was all these 2-pole breakers in his panel. Is it also a safety issue?
