A copper earthing plate, also known as a copper grounding plate or grounding electrode plate, is a flat piece of copper used in earthing systems to establish a low-resistance connection with the earth. It serves as an electrical conductor to dissipate electrical charges and provide a safe path for fault currents.

Copper earthing plates are commonly used in various applications, including residential, commercial, and industrial electrical systems. They are typically buried in the ground, either horizontally or vertically, to ensure a reliable electrical connection with the earth.

The size and thickness of copper earthing plates may vary depending on the specific requirements of the installation and the expected fault current. The plates are usually made of high-quality copper to ensure excellent conductivity and resistance to corrosion.

During installation, the copper earthing plate is securely buried in the ground, and a proper connection is made between the plate and the electrical system, such as the grounding conductor or the grounding electrode conductor, to establish an effective earthing system for electrical safety and equipment protection.
