Grounding (Earthing) is a system of electrical circuits that are connected to the ground that functions when a leakage current can discharge electricity to the earth. ... Provide a path for current flow that can provide detection of the occurrence of an undesired relationship between the system conductor and the earth.

A grounding wire gives an appliance or electrical device a safe way to discharge excess electricity. An electrical circuit relies on both positive and negative electricity. ... A grounding wire takes the electricity that has built up during the malfunction and sends it outside of your home back into the ground.
