An earth wire (also called ground wire) is a safety conductor used in electrical systems to provide a direct path for fault current to flow safely into the ground. Its main purpose is to protect people, equipment, and structures from electric shock or fire caused by insulation failure, short circuits, or lightning strikes.
Key Features of an Earth Wire:
Material: Commonly made from copper or aluminum due to their high conductivity and durability.
Color Code: Typically green, or green with a yellow stripe (depending on national standards).
Connection: Linked to the exposed metal parts of electrical equipment and connected to an earth electrode (rod, plate, mat, or tape buried in the
