The Criteria in America for full lightning security techniques include things like NFPA 780, UL ninety six & 96A, and LPI one hundred seventy five. These Benchmarks are according to the basic theory of giving a reasonably immediate, small-resistance, reduced impedance metallic route for lightning current to stick to, and generating provisions to circumvent destruction, hearth, hurt, Demise, or personal injury as The existing flows in the roof stages to underneath quality. The Requirements signify a consensus of authorities relating to primary prerequisites for building and efficiency of experienced types and solutions.
