# Current flowing through neutral to ground

The neutral wire of the 3 phase 4 wire system is 0volts compared to the ground. We also know that it provides the return path for phase currents. Under unbalanced loading, current does flow in the neutral wire as Ineutral =-( Ia + Ib + Ic)

So how does the current flow from neutral to ground through human body sometimes when both of them are at same potential ?

• You misunderstand. It flows from phase to neutral, not neutral to ground.

• Current wants to flow from neutral to ground. But normally, copper wire provides a low resistance path for the current, and it is not likely that large currents will flow through a person who touches it. But, if the low resistance pathway is broken due to a fault, then current may flow from a neutral wire through a person to ground. But, in the case there is a fault, I am not sure we should call it a neutral wire. Commented Jun 1, 2018 at 5:42
