Answer:
Grounding wire must be bare, green, or green with yellow stripes. It does not carry any current during normal operation. However, if a hot wire were to come loose and touch the frame of an appliance, the grounding wire will protect the user from shock by conducting the current from the frame back to the main service panel. From there the current goes to an earth ground as current takes the path of least resistance to reach the earth.
