UL has inspection personnel who go to generation services consistently to verify compliance for ongoing use in their authorized items labels.
Where by each one of these units are bonded to some continuous metallic h2o line program, just one connection is required involving the lightning protection grounding along with the h2o line. System interconnection may be produced at many points close to structure entrances for methods, or just one hard connection at a floor bar may very well be utilized. Bringing all creating grounded devices to precisely the same probable at quality is the initial step towards preserving inside factors and other people from lightning. It commences the bonding system in opposition to aspect flashes from process parts to inside making techniques.
In lots of conditions, structural metal, metallic railings, together with other steel fabrications can be utilized in lieu of cables. Provided the metal is not less than three/16 inch thick and will be designed electrically continual. (See report in
