Installation
The GI earthing rod is driven vertically into the ground using suitable driving tools. For lower earth resistance, multiple rods may be connected in parallel and spaced appropriately. The rod is connected to the earthing conductor using galvanized clamps or suitable connectors to ensure a secure and low-resistance electrical connection.
Standards
GI earthing rods are commonly manufactured in accordance with:
- IS 3043 – Code of Practice for Earthing
- IS 2062 – Mild Steel Specification (where applicable)
- IEC 62561 – Lightning Protection System Components
- BS 7430 – Code of Practice for Protective Earthing
GI earthing rods are a reliable and economical choice for grounding systems, offering good corrosion resistance, mechanical strength, and dependable electrical performance for a wide range of electrical installations.
