Ground or earth in a mains (AC power) 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" (North American practice)
and "earth" (most other English-speaking countries) are
used synonymously here). 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.

Answer / sankar ocet

Neutral is a return current path(under normal)

Ground is a fault current path(Under fault)
