- Description
- PART 2 PRODUCTS2.1 MATERIALS A.Attach master labels "A" or "B" to each item by its manufacturer as evidence that the materials have been manufactured in conformance with the UL Standards for master label lightning protection materials. B.In additional to conformance to UL 96, the component material requirements are as follows: 1.Conductors: Electrical grade copper. 2.Air terminals: Solid copper, not less than 9 mm (3/8 inch) diameter, with sharp nickel plated points. 3.Ground rods: Copper clad steel, not less than 13 mm (1/2 inch) diameter by 2400 mm (8 feet) long. 4.Ground plates: Solid copper, not less than 2 mm (1/16 inch) thick. 5.Tubing: Stiff copper or brass. C.Anchors and fasteners: Bolt type which are most suitable for the specific anchor and fastener installations. PART 3 EXECUTION 3.1 INSTALLATION A.Install ALL conductors as inconspicuously as practical and with the proper bends. B.RESERVED C.Make connections of dissimilar metal with bimetallic type fittings to prevent electrolytic action. D.Use the exothermic welding type connections that form solid metal joints in the main vertical and horizontal conductors, and for connections that are not exposed in the finish work. E.Protect copper conductors with stiff copper or brass tubing, which enclose the conductors from the top to the bottom of the tubing, between 300 mm (one foot) below and 2100 mm (seven feet) above the finished grade. F.Sheath copper conductors, which pass over cast stone, cut stone, architectural concrete and masonry surfaces, with not less than a 2 mm (1/16 inch) thickness of lead to prevent staining of the exterior finish surfaces. G.For the earth connections, install ground rods and ground plates, and the conductor connections to them and the main water pipes in the presence of the Resident Engineer. For the conductors located outside of the building or stack, install the conductors not less than 600 mm (two feet) below the finished grade. H.For structural steel buildings, connect the steel framework of the buildings to the main water pipe near the water system entrance to the building. I.Connect exterior metal surfaces, located within 900 mm (three feet) of the lightning protection system conductors, to the lightning protection system conductors to prevent flashovers. J.Grounding: Test the ground resistance to earth by standard methods and conform to the ground resistance requirements specified in Section 26 05 26, GROUNDING AND BONDING FOR ELECTRICAL SYSTEMS. K.Where shown, use the structural steel framework or reinforcing steel as the main conductor:
