Installing a ground wire in an outlet is a crucial safety measure that helps protect against electrical shocks and fires. A ground wire provides a path for excess electricity to safely flow into the ground, preventing it from traveling through the outlet and into appliances or the human body.
Ground wires are typically made of bare copper wire and are connected to the ground terminal in the outlet box. The ground terminal is usually identified by a green screw or a green wire nut. Once the ground wire is connected to the ground terminal, it should be secured to the outlet box using a wire staple or other approved method.
