Earthing Wire .

n earthing wire (or grounding wire) is a safety conductor that provides a low-resistance path for fault currents to reach the ground, protecting users from electric shocks and preventing equipment damage. YouTube +11. Core Materials & ComparisonChoosing the right material depends on your budget, soil conditions, and the criticality of the installation. Copper: The gold standard for conductivity and durability. Pros: Highly conductive, naturally corrosion-resistant, and lasts 40–50+ years. Cons: Most expensive option. Galvanized Iron (GI): Most common for residential and budget-conscious industrial projects. Pros: Very economical and offers high mechanical strength. Cons: Lower conductivity (10–15% of copper); zinc coating eventually wears off, leading to a shorter lifespan of 15–25 years. Aluminium: Lighter and cheaper than copper but rarely used for final earthing connections due to rapid oxidation.
