An earth rod (also known as a ground rod or earthing electrode) is a metal rod driven into the ground to provide a low-resistance path for electrical faults or lightning currents to safely dissipate into the earth. It is a key component of any earthing or grounding system.
Features and Description:
Material: Usually made from copper-bonded steel, solid copper, or galvanized steel for durability and excellent conductivity.
Shape: Long, cylindrical rod—commonly available in lengths of 1.2 m, 1.5 m, 2.4 m, or 3 m, and diameters from 12 mm to 25 mm.
Surface: The rod surface is smooth or threaded to allow easy coupling with driving heads or extensions during installation.
