In a delta, it shouldn't. But , in the real workd, there will always be small leakage currents.
In a Y configuration.... Look at the Y. The center part of the Y **is** the neutral and of **course** there will be current flowing between phase and neutral.

If the three phase load is exactly balanced, then there should be no neutral current. Any unbalanced loads will cause current to flow in the neutral line. And, certain harmonics may require neutral current.

Because Ions need a place to go, in order to make a current.
If you have just "neutral", then there is no place for the ions to travel, as they are "static" in place. The same with a phase.
But, give them a pathway to travel, and they will go from "positive" phase to a netural "ground" and along the way, become charged and lose thier charge as they pass from "hole to hole" left by the ion that preceeded it, and produce a current.
I wish you well..

This is incomplete question.You did not specify whether leakage current , load current or current in neutral wire in unbalanced 3 phase system.

because of the voltage diffence between the two.
