In residential wiring, the ground wire is typically colored green or is made of bare copper. The function of the ground wire is to provide a safe pathway for electrical current to return to the ground in the event of a fault, helping to prevent electrical shock and equipment damage. The green color is universally recognized in electrical systems as an indication of grounding, ensuring safety and compliance with electrical codes.

Using bare copper also provides a clear distinction as it is easily identifiable and avoids confusion with other wire colors that are used for different purposes, such as black for hot wires and white for neutral wires. This standardization is vital for maintaining consistency and safety across different regions and installations in residential settings.
