Which outcome occurs when a single-phase load is excessively high on one phase of a three-phase system?

💡 Explanation

When a single-phase load unbalances a three-phase system, excessive current flows through the neutral conductor because the phase currents no longer sum to zero, exceeding its capacity. Therefore neutral overload occurs, rather than transformer saturation causing heating; compensation changes; or widespread harmonic distortion which are less directly linked.
