Do not combine materials that can form an electrolytic couple that will accelerate corrosion in the presence of moisture unless moisture is permanently excluded from junction of such materials. B. Use conductors with protective coatings where conditions cause deterioration or corrosion of conductors. 3.4 FIELD QUALITY CONTROL A. At completion of the installation of the lightning protection system, the contractor shall apply for inspection of the system by UL field representatives. The system shall be inspected for compliance with NFPA 780. Notify Architect at least 48 hours in advance of inspection. B. UL Inspection: If the lightning protection system passes inspection, UL will issue a Master Label® Certificate of Inspection for Lightning Protection System. The contractor shall submit the certificate to the Owner and also publish the certificate to the UL website, https://lps.ul.com where it may be viewed by consumers, building owners, insurance agencies and other interested parties.
