Orange County Emergency Services -Generator <br />PDC Project 24030 Conduit for Electrical Systems 26 05 33.13 - 5 <br />2.Description: Fittings complying with NEMA TC 3 and listed and labeled as complying with UL <br />651;material to match conduit. <br />2.08 ACCESSORIES <br />A.Corrosion Protection Tape: PVC-based,minimum thickness of 20 mil. <br />B.Conduit Joint Compound: Corrosion-resistant,electrically conductive;suitable for use with the <br />conduit to be installed. <br />C.Solvent Cement for PVC Conduit and Fittings: As recommended by manufacturer of conduit and <br />fittings to be installed. <br />D.Pull Strings:Use nylon cord with average breaking strength of not less than 200 pound-force. <br />PART 3 EXECUTION <br />3.01 EXAMINATION <br />A.Verify that field measurements are as indicated. <br />B.Verify that mounting surfaces are ready to receive conduits. <br />C.Verify that conditions are satisfactory for installation prior to starting work. <br />3.02 INSTALLATION <br />A.Install products in accordance with manufacturer's instructions. <br />B.Install conduit in a neat and workmanlike manner tight against walls,columns or ceilings. <br />C.The conduit shall bend cold 90 degrees about a radius equal to ten (10)times its own diameter <br />without signs of flaw or fracture in either pipe or protective coverings. All bends and offsets shall <br />be made on a forming tool to prevent the conduit or its coating from being damaged in the <br />bending. <br />D.Install galvanized steel rigid metal conduit (RMC)in accordance with NECA 101. <br />E.Install intermediate metal conduit (IMC)in accordance with NECA 101. <br />F.Install rigid polyvinyl chloride (PVC)conduit in accordance with NECA 111. <br />G.Conduit Routing: <br />1.Unless dimensioned,conduit routing indicated is diagrammatic. <br />2.Conceal all conduits unless specifically indicated to be exposed. <br />3.Conduits in the following areas may be exposed,unless otherwise indicated: <br />a.Electrical rooms. <br />b.Mechanical equipment rooms. <br />4.Arrange conduit to maintain maximum headroom,clearances,and access. <br />5.Arrange conduit to provide no more than the equivalent of four 90 degree bends between pull <br />points. <br />6.Arrange conduit to provide no more than 100 feet between pull points. <br />7.In every instance,conduit shall be installed in such a manner that the conductors may readily <br />and easily be drawn or pulled in without strain or damage to the insulation;and,also,so that <br />defective conductors may be readily and easily withdrawn and replaced by new conductors. <br /> Long radius bends and a sufficient number of approved pull and junction boxes shall be <br />approved for this purpose,and as may be directed by the Engineer. All conduit shall be <br />securely supported and grounded. <br />8.Arrange conduit to prevent moisture traps.Provide drain fittings at low points and at sealing <br />fittings where moisture may collect. <br />9.Where conduits join any couplings or threaded fittings,the ends shall be made watertight. <br />10.Maintain minimum clearance of 12 inches between conduits and hot surfaces.This includes, <br />but is not limited to: <br />H.Conduit Support: <br />Docusign Envelope ID: DEDB83DA-7916-8AE5-81B0-AA1EA4D56AE9
