Proper earthing is crucial to ensure safety and operational efficiency in an electrical system. If the meter room's HRC switch does not have proper earthing, it may lead to potential hazards such as voltage surges, electric shocks, or even equipment damage. In your case, since the 11kV transformer output is going into the HRC main three-phase each, the switches require proper earthing for grounding excessive voltages and protecting the system from overcurrents.nAs for customer-made earthing at homes, it's important to ensure that these earthings are properly connected to the utility company's grounding network to avoid potential safety issues.
