A Copper Bonded Earth Rod, also known as Copper Clad Earth Rod, is a type of grounding electrode used to provide a low resistance path for the flow of electrical current to the ground. It consists of a steel core that is coated with a layer of copper, typically through a process of electroplating. Copper Bonded Earth Rod is installed vertically in the ground and connected to the grounding system using a suitable connector or terminal lug.
