in three pin plug 6 Amp. 220v AC rating.
why earth pin diameter is higher than ohter two pin? what its
purpose ?
Answer Posted / kishore kumar
because R=Pl/a area of the conductor increases resistance
value dicreases .so high lekage current flows it thats why
the area of the earthing pin is big compare yhe phase and
neutral pins.
