Why include SP 30
The National Electrical Code provides broader electrical-installation guidance and references relevant Indian standards. It helps prevent the lightning-protection system from being designed without considering the rest of the electrical installation.
Website use
Use SP 30 as a coordination/reference page. Detailed lightning risk and LPS geometry remain under the applicable IS/IEC 62305 design framework.
Project checks
Confirm electrical supply arrangement, earthing system, service entries, switchboards, protective devices, critical systems, renewable/DC systems and maintenance/inspection responsibilities.
