A copper earthing electrode is a component used in earthing systems to provide a low-resistance path for electrical current to flow into the ground. It is commonly used in electrical installations, including buildings, substations, and power systems.

Copper is a popular choice for earthing electrodes due to its excellent electrical conductivity and corrosion resistance. Copper electrodes are typically in the form of rods or plates that are buried in the ground to establish a reliable electrical connection with the earth.

The installation of a copper earthing electrode involves driving the electrode into the ground and ensuring proper electrical contact. It helps to dissipate electrical faults, lightning strikes, and other electrical surges, thereby protecting electrical equipment, buildings, and people from potential electrical hazards.
