Install products in accordance with manufacturer's instructions. <br /> B. Perform work in accordance with NECA 1 (general workmanship). <br /> C. Install galvanized steel rigid metal conduit(RMC) in accordance with NECA 101. <br /> D. Install intermediate metal conduit (IMC) in accordance with NECA 101. <br /> E. Install rigid polyvinyl chloride (PVC) conduit in accordance with NECA 111. <br /> F. Conduit Support: <br /> 1. Secure and support conduits in accordance with NFPA 70 and Section 26 05 29 using <br /> suitable supports and methods approved by the authority having jurisdiction. <br /> 2. Provide independent support from building structure. Do not provide support from piping, <br /> ductwork, or other systems. <br /> G. Connections and Terminations: <br /> 1. Use approved zinc-rich paint or conduit joint compound on field-cut threads of galvanized <br /> steel conduits prior to making connections. <br /> 2. Where two threaded conduits must be joined and neither can be rotated, use three-piece <br /> couplings or split couplings. Do not use running threads. <br /> 3. Use suitable adapters where required to transition from one type of conduit to another. <br /> 4. Terminate threaded conduits in boxes and enclosures using threaded hubs or double lock <br /> nuts for dry locations and raintight hubs for wet locations. <br /> 5. Provide insulating bushings or insulated throats at all conduit terminations to protect <br /> conductors. <br /> 6. Secure joints and connections to provide maximum mechanical strength and electrical <br /> continuity. <br /> H. Penetrations: <br /> 1. Do not penetrate or otherwise notch or cut structural members, including footings and grade <br /> beams, without approval of Structural Engineer. <br /> 2. Make penetrations perpendicular to surfaces unless otherwise indicated. <br /> 3. Provide sleeves for penetrations as indicated or as required to facilitate installation. Set <br /> sleeves flush with exposed surfaces unless otherwise indicated or required. <br /> 4. Conceal bends for conduit risers emerging above ground. <br /> 5. Seal interior of conduits entering the building from underground at first accessible point to <br /> prevent entry of moisture and gases. <br /> 6. Where conduits penetrate waterproof membrane, seal as required to maintain integrity of <br /> membrane. <br /> 7. Install firestopping to preserve fire resistance rating of partitions and other elements, using <br /> materials and methods specified in Section 07 84 00. <br /> I. Underground Installation: <br /> 1. Minimum Cover, Unless Otherwise Indicated or Required: <br /> a. Underground, Exterior: 24 inches. <br /> J. Conduit Movement Provisions: Where conduits are subject to movement, provide expansion and <br /> expansion/deflection fittings to prevent damage to enclosed conductors or connected equipment. <br /> This includes, but is not limited to: <br /> 1. Where conduits cross structural joints intended for expansion, contraction, or deflection. <br /> 2. Where calculated in accordance with NFPA 70 for rigid polyvinyl chloride (PVC) conduit <br /> installed above ground to compensate for thermal expansion and contraction. <br /> 3. Where conduits are subject to earth movement by settlement or frost. <br /> K. Provide grounding and bonding in accordance with Section 26 05 26. <br /> 3.03 FIELD QUALITY CONTROL <br /> A. Repair cuts and abrasions in galvanized finishes using zinc-rich paint recommended by <br /> manufacturer. Replace components that exhibit signs of corrosion. <br /> 3.04 CLEANING <br /> A. Clean interior of conduits to remove moisture and foreign matter. <br /> PDC Project 18102 CONDUIT FOR ELECTRICAL 26 05 33.13 -4 <br /> 12/17/2018 SYSTEMS <br />
