Install strictly to the manufacturer’s written instructions and IS 3043. The electrode top shall be permanently sealed with conductive concrete and the copper strip shall terminate at an accessible earth test point. Submit pre- and post-installation test results using an approved earth-resistance tester. For a lightning-protection earth, the measured resistance shall not exceed 10 ohms, or the lower value stated in the approved design. Do not use a material-resistivity claim as a substitute for measured earth resistance. |
