Grounded Outlet

A grounded outlet has three holes for each plug. It is essential to the safe and reliable operation of certain electrical equipment. In a properly wired outlet, the rounded slot is the ground connection. Electrical grounding ensures that if there is ever a short circuit on a piece of electrical equipment, current will flow through the ground system and trip a breaker or blow a fuse. A grounded outlet must be used correctly to provide good protection:

• Never cut off the third grounding prong on an appliance plug.
• Don't try to install a grounded outlet in an ungrounded receptacle. Use "cheater" adapter plugs only on a temporary basis.
  
• When using these devices, make sure the small metal circle on the bottom contacts the screw in the middle of the outlet.
