SynC · Topic
These are the standards in the SynC Standards library that cover Lightning Protection. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Structural lightning protection systems for buildings and ordinary structures, covering air terminals and strike termination, main and down conductors, conductor materials and dissimilar-metal limitations, grounding electrodes and the ground ring, bonding and potential equalization of metal bodies, and coordination of surge protection at the electrical service. Applies to new construction and retrofit of commercial, institutional, and industrial structures seeking a UL Master Label or LPI-certified system.
