An earthing clamp is a device used to connect electrical equipment or systems to the earth for safety purposes. It typically consists of a metal clamp or clip that is designed to securely fasten onto a conductive surface, such as a grounding rod or metal pipe. The clamp is then connected to an electrical cable, which is in turn connected to a ground or earth terminal. Earthing clamps are commonly used in electrical installations and grounding systems to protect against electrical shocks, static discharge, and lightning strikes. They are available in a range of sizes and materials to suit different applications and environments.
