The radius of a bend in a lightning conductor must not be less than how many inches according to LPI-175?

According to LPI-175 guidelines, the minimum radius of a bend in a lightning conductor is specified to be no less than 8 inches. This requirement is in place to ensure that the conductor maintains its structural integrity and optimal conductivity. A bend with sufficient radius helps prevent potential damage or crimping of the conductor, which can occur if the bend is too sharp. Such damage could lead to increased electrical resistance or failure of the lightning protection system to perform effectively.

Maintaining a minimum bend radius is critical in lightning protection design, as it ensures the conductor can handle the high currents and rapid energy discharge associated with lightning strikes without compromising its performance or reliability. This standard is crucial for effective lightning protection, ensuring safety and functionality in protecting structures from lightning hazards.
