Earth clamps are electrical connectors that are used to create a secure and reliable connection between an electrical circuit and the earth (ground). They are typically made of metal, such as copper or brass, and are designed to attach to a grounding conductor, which is then connected to an earth electrode, such as a grounding rod or plate.

Earth clamps are used in a wide range of applications, including in electrical and electronic equipment, power systems, and building grounding systems. They play a critical role in ensuring electrical safety by providing a low-impedance path to the ground, which helps to protect against electric shock, power surges, and lightning strikes.

Earth clamps come in many different shapes and sizes, and may include features such as serrated teeth or serrated jaws to provide a better grip on the grounding conductor, or a set screw to secure the conductor in place. Some common types of earth clamps include pipe clamps, rod clamps, plate clamps, and grounding strap clamps.
