Answer Posted / bhatt
As we know earth is connected to the body of
equiment/machine hence if earth terminal is longer then
earth will be connected to body of equipment/machine first
thereafter phase and neutral. It is bigger size because it
must not go in phase & neutral terminal by any mistake so
as to avoid any direct contact of body of machine with
phase/neutral.
