Earth is the universal reference which is assumed to be at
ZERO potential. While neutral is the common connection
between three phases in a star connected circuit. Earth is
essentialy at zero potential while neutral potential
depends on the unbalance between the phases.If the phases
are balanced, neutral has zero potential while in case of
unbalanced system, neural has some finite potential.

Answer / pyobik

yes there may be, as because zero potential is termed only
for earth.
