If there is imbalance in the load, like someone using 0A on two phases and 1A on one phase, then there is no other return path for the 1A except for the neutral wire. Yes, neutral current is also a sine wave and instantaneous sum of phase currents. The point is with balanced load the phase currents sum to zero so there is no imbalanced currents that would flow via neutral. | |
