NEUTRAL is a return path of current in single phase loads.
However in a balanced three phase loads NEUTRAL will not
carry any current. In case of unbalanced three phase load
conditions NEUTRAL will carry algebraic sum of all three
phase currents.
EARTH wire is connected to a metallic body (non-live) parts
of a machine. In case of insulation failure EARTH wire will
act as a return path, to protect humans from electric shock.
For better protection, resistance of EARTH wire is
maintained below 5 ohms.
