You may not expect current in neutral of a 3phase
appliance. But there will be current in neutral of a 1
phase appliance while working.,

Answer / pillay

your understanding is wrong or if not
incomplete.
In any single phase circuit the neutral
is the return path
for the circuit. That means the current that
flows into the phase comes out through the neutral
Even in 3 PH balanced load you will see the
same individual ph current in the neutral but
you will see no current in the main neutral,
cos at the neutral bar the individual neutral
current had balanced up through the other phases.
