How does the diameter of copper bonded earthing rods influence their grounding efficiency and durability?
The size of a copper bonded earthing rod is important in defining its grounding efficiency, mechanical strength, and lifespan. Larger rods, e.g., 14mm or 17mm sizes, offer lower fault current resistance, allowing for more effective dissipation of electrical energy to the ground. Thinner rods, on the other hand, can have greater resistance, causing
