The ground wire serves as a safety mechanism by directing excess electrical charges safely into the earth in case of a short circuit or electrical fault. This prevents dangerous currents from passing through equipment or humans, reducing the risk of electric shock and fire hazards . It also stabilizes the electrical system by maintaining a reference voltage for all components .
Inside a distribution box, the ground wire is typically connected to a grounding bar or PE (Protective Earth) bar. Electrical components that require grounding are linked to this bar using copper wires, ensuring that all parts share a common grounding point . The wire is usually yellow-green insulated, with a cross-sectional area meeting local electrical codes to ensure proper conductivity and safety .
Connecting the receptacle grounding terminal to the metal box ensures an effective ground-fault current path. The
