Ever Wondered Why Some Plugs Have 3 Prongs Instead Of 2?
It accomplishes this by being connected to the shell of the appliance and it goes through the outlet and down into the ground.
Any current would be directed down there instead of through your body.
This would take that current, even if it's running through the shell of the appliance, and lead it away.
This way even if you touch it, you would still be safe.
Some people remove this bottom prong if they don't have a three holed outlet, but you should know that it's very dangerous to do so.
If that current has nowhere to go, you could be electrocuted.
