NORMALLY 3 COPIES ARE REQUIRED. DISTRIBUTION AFTER REVIEW IS NORMALLY 1 COPY TO THE CO, 1 COPY TO THE CONTRACTOR, AND 1 COPY TO THE PROJECT FILE. ***************************************************** D.Certification: Provide three copies of a UL Master Label from the supplier of the contractor-furnished lightning protection system to be used on this project.(# 1.5QUALITY ASSURANCE A.Labeling Requirements: Major lightning protection system components shall be Underwriter's Laboratories, Inc. (UL) listed and labeled. UL listing and labeling will not be required if it can be shown that system components meet the requirements of another nationally recognized testing laboratory (NRTL).(# /%0*s's'ԌPART 2: PRODUCTS 2.1MATERIALS A.General: Lightning protection system components shall be constructed of the manufacturer's standard materials, as listed in published product information; types and sizes shall be as indicated or as required for the installation.(#  2.2OVERALL REQUIREMENTS(# A.General: Provide lightning protection system components of types, sizes, and ratings as required for a complete installation. Use Class I or Class II materials as set by structure height. Where size is not shown, use minimum size allowed by NFPA 78. Minimize use of dissimilar metals in contact. Provide a protective hot-dip-lead covering over copper air terminals or fittings in direct contact with chimney gases. Building structural steel shall be incorporated into the lightning protection system wherever feasible in metal framed or metal clad buildings.(# 2.3CONDUCTORS A.General: Conductors used in the lightning protection system shall be copper or copper alloy of at least 95% conductivity. Minimum size of main conductor for Class I material shall be cable equivalent to 57,400 circular mils in area, with individual strands of No. 17 AWG wire, and total weight not less than 0.187 lb/ft. Solid strip main conductor, minimum size of 0.051 thick by 1-inch wide, may be used where necessary to encircle large diameter metal objects. For secondary conductor, the minimum size may be reduced to 26,240 circular mils for cable and 0.51-inch thick by 1/2-inch wide for strip. Minimum size conductor for Class II material is found in NFPA 78. Ground terminal conductor shall be the same size as the downlead and shall also be stranded.(# 2.4ACCESSORY COMPONENTS A.Air Terminals: Terminals shall be of solid or tubular copper or copper alloy. Bases and attachment plates shall be solid bronze.(# B.Connectors: Connectors shall be bronze of the correct size and type for connecting the cables involved and for the location of use.(# C.Fasteners: Fasteners shall be of the same material as conductor or of a material equally corrosion resistant. No combination of materials shall be used which forms a corrosion cell.(# D.Ground Rod: Copperweld ground rods 5/8-inch in diameter by 8 ft long shall be used.(# E.Ground Rod Clamp: Bronze clamp suitable for attaching downlead to rod or suitable for attaching both copper downlead and protective conduit to rod, if metal conduit is used.(# F.Surge Arresters: Arresters are specified in Section 13101 - Lightning Arresters.(# G.Bonding Plates: Connections to cleaned areas of the building steel shall be made by use of bonding plates with bolt pressure cable}&0*s's'  r5 connectors having a surface contact area of not less than 8-in2, bolted, welded, or brazed securely to the building steel.(#  PART 3: EXECUTION 3.1INSTALLATION A.General: Install lightning protection systems as indicated, complying with the manufacturer's written instructions, applicable requirements of codes and standards (particularly LPI 175), and according to recognized industry practices. Concealed or semi-concealed conductors are required where building structure allows.(# B.Corrosion: Protect lightning protection system conductors and components from corrosion by avoiding the use of dissimilar materials, sealing between dissimilar materials, and use of protective coverings. Where dissimilar metals must be in contact, take steps to exclude moisture from the joint.(# C.Mechanical Injury: Protect lightning protection system conductor where it is exposed to injury. Where conductor is installed in conduit or metal tubing, it shall be bonded to the conduit or tubing at both ends.(# D.Bends: No conductor in the lightning protection system shall be bent to form an included angle of less than 90 degrees nor have a radius of bend of less than 8 inches. Conductor shall be fastened to the building at intervals not to exceed 3 ft.(# E.Arresters: Install arresters as close as practical to the point of entry of electric and telephone service entrances, and on radio and TV antenna lead-ins.(# F.Bonding: Grounding medium shall be bonded together. This includes lightning protection, [electric,] [telephone,] [antenna system grounds] [and] [grounds to underground piping systems] which enter the structure. Primary and secondary metal bodies shall be grounded as required by NFPA 78.(# 3.2FIELD QUALITY CONTROL A.Ground resistance: The Contractor shall test resistance-to-ground of the lightning protection system with a resistance tester. Where resistance-to-ground is over 5 ohms, the Contractor shall take action to reduce it to 5 ohms by driving up to two additional ground rods for each rod shown. When resistance still exceeds 10 ohms, notify the Contracting Officer of the steps that can be taken to reduce the ground resistance to below 10 ohms.(#  PART 4: MEASUREMENT AND PAYMENT ***************************************************** WHEN A "LUMP SUM" CONTRACT IS USED, DELETE THE TITLE PART 4: MEASUREMENT AND PAYMENT, AND BOTH ARTICLES FROM THIS SECTION.
