Earthing Protection Clause Samples

The Earthing Protection clause establishes requirements for the proper grounding of electrical systems to ensure safety and prevent electrical hazards. It typically mandates that all electrical installations are equipped with adequate earthing systems, such as grounding rods or conductors, and that these systems are regularly inspected and maintained. By specifying these standards, the clause helps to minimize the risk of electric shock, equipment damage, and fire, thereby protecting both personnel and property.
