Lightning protection and grounding of mobile optical distribution boxes
This Recommendation provides guidance on protecting indoor distribution systems for mobile communication in large-scale buildings from lightning and safety risks. It emphasizes compliance with standards like IEC 62305-3, IEC 62305-4, IEC 60364 series, and ITU-T K. 21 for effective. We make safe, reliable and high-quality solutions for every spec and project. Lightning protection needs vary according to each specific facility. It is located at an elevation such that a line passing through the static wire and the outermost conductor below it is at a 30° aximum angle with a vertical line. ERICO® has complete telecommunications applications solutions to help protect the facility against electrical noise, lightning induced surges and transients caused by. Ground rods are the most common grounding electrode found on distribution circuits.
