You may be see the earth pin is longer & bigger in diameter.due to more dia. its pin resistance would be less & due to longer size as compare other two pins, earth pin come in contact of circuit first so. for safety point of view we need your apparatus / instrument connect with earth first. Under fault condition, the faulty current will be flow through earth pin S0. you & your instrument/ apparatus is safe
