Answer Posted / abdul nazir
Earth pin diameter is bigger than phase & neutral, because
conductor area increases its resistance will be reduce, so
fault current will easily flow through this path, this is
the reason why earth pin is bigger than other two pins.
compare to other two pins, the earth pin LENGTH also more,
because every electrical equipment should earth first.
(safety reason).
And also we cant insert(by mistake) the earth pin to phase
hole(plug).
