what is diff. b/w of earth & neutral?. why we are
separately using ?

Answer Posted / 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.
