ORANGE COUNTY 230511 - 6 <br /> <br />Emergency Management Warehouse Building Dehumidification Electrical Provisions for HVAC Work <br /> <br /> <br />PART 3 - EXECUTION 1 <br /> 2 <br /> 3 <br />GENERAL 4 <br /> 5 <br />Coordinate the exact location of all equipment disconnects to ensure that disconnects are located within sight of 6 <br />mechanical equipment. 7 <br /> 8 <br />Extend power wiring circuits from load side of termination points provided under Divisions 26-28 to each item of 9 <br />mechanical equipment requiring electrical power. All wiring shall be installed in raceway. All wiring and raceway 10 <br />shall be in compliance with Division 26. Utilize liquid tight flexible metallic conduit for weatherproof for outdoor 11 <br />locations. Provide all necessary clamps, fitting, connectors, raceways, circuit conductors, etc., for a completely 12 <br />operational system. 13 <br /> 14 <br /> 15 <br />INSTALLATION OF CIRCUIT AND MOTOR DISCONNECTS 16 <br /> 17 <br />Install disconnects as indicated, complying with manufacturer's written instructions, applicable requirements of NEC, 18 <br />NEMA, and NECA's "Standard of Installation," and in accordance with recognized industry practices. 19 <br /> 20 <br />Coordinate placement of disconnects with electrical raceway and cable work, as necessary for proper interface. 21 <br />Coordinate exact location of disconnects with equipment electrical connection point. 22 <br /> 23 <br />Locate disconnects so that they are readily accessible after all project elements are installed. Location 24 <br />selected for disconnects must permit complete opening of the door or cover to the maximum amount 25 <br />permitted by the design of the switch enclosure. 26 <br /> 27 <br />Install disconnects for use with motor-driven appliances and motors within sight of the controllers, as indicated on the 28 <br />Drawings. In addition, each motor shall be provided with an approved disconnecting device within sight of the 29 <br />respective equipment as required by the NEC even though not specifically indicated on the Drawings. Disconnects 30 <br />installed for use with controllers may serve as the disconnecting means for the motor if it is in sight from the motor 31 <br />location and the driven machinery location. 32 <br /> 33 <br /> 34 <br />INSTALLATION OF STARTERS 35 <br /> 36 <br />Install starters as indicated, complying with manufacturer's written instructions, applicable requirements of NEC, 37 <br />NEMA, and NECA's "Standard of Installation," and in accordance with recognized industry practices. 38 <br /> 39 <br />Coordinate placement of starters with electrical raceway and cable work, as necessary for proper interface. 40 <br />Coordinate exact location of starters with equipment electrical connection point. 41 <br /> 42 <br />Locate starters so that they are readily accessible after all project elements are installed. Location selected 43 <br />for starters must permit complete opening of the door or cover to the maximum amount permitted by the 44 <br />design of the switch enclosure. 45 <br /> 46 <br /> 47 <br />GROUNDING 48 <br /> 49 <br />Provide equipment grounding connections, sufficiently tight to assure a permanent and effective ground, for electrical 50 <br />combination motor starters. All combination starters shall be grounded by means of a separate insulated grounding 51 <br />conductor, run with the ungrounded conductors, and bonded to the starter enclosure by means of a dedicated 52 <br />grounding screw terminal or bus. 53 <br /> 54 <br /> 55 <br />FIELD QUALITY CONTROL 56 <br /> 57 <br />Subsequent to completion of installation of disconnects and motor starters, energize circuitry and demonstrate 58 <br />capability and compliance with requirements. Where possible, correct malfunctioning units at project site, then retest 59 <br />to demonstrate compliance; otherwise remove and replace with new units and retest. 60 <br />61 <br />DocuSign Envelope ID: 7668B866-6C26-485C-9A45-DAAB5D4BD951
