Answer Posted / lionking
neutral is a reference point and a return path for any
"live" circuit. Earth is an energy ZERO point.
When ALL phase has balanced load, neutral should be ZERO
volt in respect to earth. Becareful the word "balanced",
which means, when there is an unbalanced phased (due to load
or otherwise), the neutral will no longer be ZERO volt in
respect to earth. When there is more than ZERO volt between
neutral and earth, then there will be current flow through
these 2 points (leakage).
Even for most of the time, neutral and earth has ZERO volt
between them; they should never be connected together or be
used interchangeably.
