NFPA 780 provides guidelines for how often to place air terminals, spacings for cross and down conductors, ground rod and loop requirements, surge-protection requirements, and how to install protection for trees, towers, etc. . The purpose of NFPA 780 is to provide for the safeguarding of persons and property from hazards arising from exposure to lightning. The scope is limited to covering traditional lightning protection systems that are installed on: Chapter 1 of NFPA 780 covers the aforementioned items but also delves. . This tried and true standard issued by the same group that writes the National Electric Code (The NFPA), provides an excellent guideline for installing a straightforward one-size-fits-all lightning protection system. In fact, according to the National Fire Protection Association. . For grid-scale battery energy storage systems (BESS), grounding and bonding is essential for safety and performance. Please follow the National Electric Code (NEC) or the local Electrical. .
