    Code Clarification 310.15 (B) (5) (a) Neutral Conductor

    (5) Neutral Conductor.
    (a) A neutral conductor that carries only the unbalanced
    current from other conductors of the same circuit shall not be
    required to be counted when applying the provisions of
    310.15(B)(3)(a).

    My question is basically when is it called the “SAME CIRCUIT”
    Is this only relevant when it's connected to any single device? i.e. a Panel, ac, appliance?
    Or is it also at any multi wire branch circuit?
    In other words what is the definition of “SAME CIRCUIT”

    This came up at a code refreshing course last night, and it went back and forth
    I would appreciate your input on this

    Thanks all

    If Billy Idol or John Denver is on your play list go and reevaluate your life.
