The electrical ground is the backup safety system for the wires; it provides a safe path to the earth for electricity that gets somewhere it shouldn't. There are several ways to ground an electrical system including using grounding rods and metal water-service pipe. The size of the ground wire is determined by the amount of electricity delivered to your home. Have your installation inspected by your local building authority before turning on the power.
