For new installations, therefore, a public water pipe may not be used as a means of earthing. Metallic pipe systems of services other than water service (for example, for flammable liquids or gases, heating systems, etc ) shall not be used as earth electrodes for protective purposes. Bonding of the water service with the exposed metalwork of the electrical installation (o n the consumers' side of any insulating insert) and any other extraneous metalwork to the installation earthing terminal is, however, permissible and indeed necessary in most circumstances subject to the provision of earthing facilities that are satisfactory before these bonding connections are made. For existing installations in which a water pipe is used as a sole earth electrode; an independent means of earthing should be provided at the first practicable opportunity We, at Atul Casting and Metal Works manufactures all earthing related products such as G.I Strips, G.I plates, G.I Rods, G.I Pipes, C.I covers, Cable Trays, G.I Wire, Manhole Covers and Route Markers for past 50 + Years in heart of New Delhi.
