The earthing conductor lies at the heart of electrical safety. From a domestic lighting circuit to a commercial power installation, a robust earthing system ensures that any fault current has a clear, low-resistance path to earth. This protects people, equipment and buildings, and it helps electrical protective devices operate correctly when faults occur. In this…
