UL 96A

The document is intended to assist code authorities, designers, and installers to develop, and install a complete lightning protection system that can withstand the tremendous power of a lightning strike. Depending on the type, a strike can exceed 300,000 Amperes, over one gigavolt (one billion volts) and with temperatures as high as 36,000 Deg. F., or about three times as hot as the surface of the sun. This guide does not include information on protection of equipment inside a building.
