The Purpose Behind Electrical Grounding | Best Pick Reports
The ground leg, the third round leg on most power cords, is designed for safety. Many appliances, such as computers, are encased in metal. If the case is not properly grounded and an electric short occurs in the appliance, it is possible for the case to become electrically charged. The ground provides a path for electricity to travel safely out of the house and into the earth in an emergency. Breaking off the ground leg on a power cord is dangerous. By breaking off the ground leg, the homeowner typically assumes all liability for the appliance or product and voids all manufacturer’s warranties.
