IS 30432018 – Code of Practice for Earthing

Earthing, also known as grounding, is one of the most critical safety measures in electrical installations. It provides a path for fault currents to safely flow into the ground, preventing damage to equipment and safeguarding human lives from electric shock. To ensure uniformity and reliability in earthing practices, the Bureau of Indian Standards (BIS) has published IS 3043:2018 – Code of Practice for Earthing (Second Revision). This standard offers detailed guidelines for design, installation, testing, and maintenance of earthing systems across industries, substations, residential and commercial buildings.
