Answer / umesh kumar
If urLoad is balanced in three Phase supply system Neural
current is Zero . neutral current is always depend on the
Unbalance load. So in Case of 3 phase system neutral wire
taken half of Main wire.
but in case of 1 phase supply system neutral is the return
cunductor and phase current will be equal to neutral curent.
so In 1 phase neural would be of same size.

Answer / imran
In three phase neautral has no current. Only at unbalanced
load there is flow of current in nutral that is why it is
half the phase size

Answer / ikab
In three phase, current in neutral in one third
of phases so conductor size is less. but in single phase neutral conductor size should be same as phase conductor size.
