I'm figuring you're talking about branch circuits. It was neutral. Some called it common. I'm not old enough to have seen any DC.
I sure wish the NEC would call this a "veeblefetser" or something. It confuses the heck out of most of the help when you start talking grounded and grounding conductors.
(BTW veeblefetser is from 1960-MAD magazine)
