F. Operational and Maintenance Manuals.FTWIC-2235June 20091.05 STANDARDS AND REFERENCES:Refer to Section 16010, GENERAL REQUIREMENTS FOR ELECTRICAL WORK, for allstandards which apply to this section.PART 2.00PRODUCTS2.01 MATERIALS:A. Materials used in connection with the installation of the lightning protection systemsshall be approved for lightning protection systems by the Underwriters' Laboratories, Inc.No combination of materials shall be used that form an electrolytic couple of such anature that corrosion is accelerated in the presence of moisture unless moisture ispermanently excluded from the junction of such metals. When unusual conditions existwhich would cause deterioration or corrosion of conductors, conductors with suitableprotective coatings or oversize conductors shall be used. If a mechanical hazard isinvolved, the conductor size shall be increased to compensate therefore, or suitableprotection shall be provided. The conductors may be protected by covering them withmolding or tubing preferably made of wood or nonmagnetic material. If metal tubing isused, the conductor shall be electrically connected to it at its upper and lower ends.B. All equipment used shall be new and of a design and construction to suit the applicationin accordance with UL 96A requirements and shall be so marked. Aluminum shall onlybe used on aluminum roofs, aluminum siding or other aluminum surfaces. Bronze andstainless steel may be used for some components. Bimetallic connectors shall be used forinterconnecting copper and aluminum conductors. Aluminum materials shall not be usedon surfaces coated with alkaline-base paint, on or embedded in masonry or cement, oncopper roofing, in contact with copper materials, or underground.2.02 MANUFACTURED PRODUCTS:A. CONDUCTORS:Copper conductors manufactured of copper grade ordinarily required for commercialelectrical work generally designated as being 98 percent conductive when annealed.Down conductors of copper cable for installations other than towers shall weigh not lessthan 187.5 pounds per thousand feet and the size of any wire of this cable shall be notless than No. 17 AWG (0.045 inch). Down conductors shall be tinned. The thickness ofany copper ribbon or strip shall be not less than No. 16 AWG (0.051 inch). Copperconductors used shall be not less than No. 15 AWG (0.057 inch), or as shown on thedrawings.B. AIR TERMINALS:Air terminals shall be tapered to a blunt point. The rod shall be of solid copper, 5/8 inchin diameter. Special length air terminals shall be provided where shown on the drawingsand both rod and support shall be designed to handle a 75 pounds per square foot windload. Air terminals shall be located in accordance with the requirements of NFPA 78016670-2
