The ground blade on a three blade plug (cap) is to provide a low impedance return to the voltage source. If the portable equipment develops a short in its circuit and goes to ground, it is this blade that will carry the short circuit current back to the supply distribution panel and trip the breaker open to cut off the supply voltage.
