I think he might mean the holes in the prongs themselves, but I don't know what the purpose is.
Each of the "prongs" on my power cords, has a small hole in it.

If you are referring to the round ground or earthing pin (American standard NEMA 5-15/Canadian standard CSA 22.2, Nº42). It is rated for 15 amperes at 125 volts. The ground pin is longer than the live and neutral blades, so the device is grounded before the power is connected. The neutral blade in the type B socket is wider than the live one to prevent type A plugs being inserted upside-down, but type B plugs often have both pins narrow since the ground pin enforces polarity.

with all respect to the previous guys who answered the qestion , Idon't think this is the right answer for it.
He may mean the cord it self , usually we have a hole in each blade of the live and the neutral . Not in the receptical !!

For the prongs? Am I hearing you right?? The larger appliances like washers and dryers need more electric current.
