Answer / vishal

Earth point is given to divert zero sequence current which
arise in case of earth fault.Neutral conductor is given for
a return path in circuit.Neutral is earthed in case of MV
and Hv equipments as to stop high currents from reaching the
equipment.

Answer / pillay

For an electrical equipment to function the circuit must be
complete.Neutral is the return path of the circuit.wheres
the earth is a protection circuit. If for some reasons the
equipment or the circuit is faulty and there is a leakage
of electricity. It may harm YOU or somebody than the you or
the somebody must be protected against the shock or death
because of it. So a earth cable is connected to ground away
any leakages or shocks so the equipment is safe to be
touched,when you actually dont know there is a fault in the
equipment.The earth cable should be connected to all the
likely places the voltage can leak to and earthed with a
good earth otherwise it is no use.With no neutral the
equipment may not work but no earth the equipment can work.

Answer / jaison

In electrical wiring system is a conductor that provides a
low impedance path to the earth to prevent hazardous
voltages from appearing on equipment (the terms "ground" .
Normally a grounding conductor does not carry current.
Neutral is a circuit conductor (that carries current in
normal operation), which is connected to earth (or ground)
generally at the service panel with the main disconnecting
switch or breaker.
