Ever Wondered Why Some Plugs Have 3 Prongs Instead Of 2?

We have all seen the different kind of outlets that are in our walls. They seem to be different wherever you go. A lot of people wonder why there are three on some while there are only two on some others. On the outlets that have three holes, two of them actually go to the same source. The one on the left and the one on the bottom are the neutral and ground wires and when you follow them you realize they go to the same place.

This is your basic 3 hole outlet.

Most appliances that are made of metal use the three prong electrical cords. These would be toasters, computers, stoves, refrigerators and such.

The third prong on these devices is to protect you from the appliance itself.

Here is an old 2 hole outlet. You probably wouldn't want to use this one!

On rare occasions, there is a wire inside that may come loose and start to conduct electricity along the metal surface. This wouldn't be good for anyone that might touch it. That third prong eliminates that issue from happening.
