Electric Plugs, Ground Connection
Definition : Electric plugs designed to be permanently connected to earth (i.e., grounded) through an appropriate matching electric receptacle. These plugs usually include three prongs (e.g., neutral, live, and earth) instead of only two; the third prong couples to the receptacle in such a way that is permanently connected to the ground; in the event of current leakage to the equipment chassis, the electricity flows through the ground wire to earth. Ground connection electric plugs are used mainly to connect an appliance to a power supply; they must be plugged into a properly wired receptacle to provide protection against shock and damage to sensitive equipment.
