    Answer:

    0\%

    Explanation:

    A 3-wire, 120/ 240 V circuit from a three-phase delta transformer contains two ungrounded conductors and one grounded conductor. The  grounded conductor carries the unbalanced current when the circuit is not balanced.

    A neutral conductor has the same equal potential between it and all ungrounded conductors of a 3-wire system.

    The current on the neutral conductor is 0\% percent of the ungrounded conductor current.
