The LPI contractor we have hired has informed us that LPI will not certify a Catenary system. Is this correct information?
I’m not sure why we couldn’t provide LPI Certification for a catenary or overhead line system. The critical factors are that the installation is made under the supervision of an LPI Certified Master Installer, the materials are provided by a listed lightning protection product manufacturer and UL listed, there is an as-built drawing submitted, and the application form is filled out with signatures by a representative of the owner confirming any concealed work. The design of an overhead line system is covered in the current editions of the LPI # 175 Standard and in NFPA 780 Standard – Chapter 7. The additional requirement we have now for any structural protection system, except residential, is a final inspection by an independent third-party — Underwriters’ Laboratories, Inc. (UL) after project completion. Since the UL 96A inspection document does not include catenary systems, this does not fall within their normal procedure or Master Label program. They do, however, inspect to other
