Construction Documents <br />20052.02 / Orange County - Justice <br />Facility <br />26 0519 - 2 POWER CONDUCTORS AND <br />CABLES <br />1.06 DELIVERY, STORAGE, AND HANDLING <br />A.Receive, inspect, handle, and store conductors and cables in accordance with manufacturer's <br />instructions. <br />1.07 FIELD CONDITIONS <br />A.Do not install or otherwise handle thermoplastic-insulated conductors at temperatures lower <br />than 14 degrees F, unless otherwise permitted by manufacturer's instructions. When installation <br />below this temperature is unavoidable, notify Architect and obtain direction before proceeding <br />with work. <br />PART 2 PRODUCTS <br />2.01 CONDUCTOR AND CABLE APPLICATIONS <br />A.Do not use conductors and cables for applications other than as permitted by NFPA 70 and <br />product listing. <br />B.Provide single conductor building wire installed in suitable raceway unless otherwise indicated, <br />permitted, or required. <br />C.Nonmetallic-sheathed cable is not permitted. <br />D.Service entrance cable is not permitted. <br />1.For underground service entrance, installed in raceway. <br />2.02 CONDUCTOR AND CABLE GENERAL REQUIREMENTS <br />A.Provide products that comply with requirements of NFPA 70. <br />B.Provide products listed, classified, and labeled as suitable for the purpose intended. <br />C.All conductors shall be labeled two feet on centers indicating size, type, voltage, rating, and <br />manufacturer's name. <br />D.Provide new conductors and cables manufactured not more than one year prior to installation. <br />E.Unless specifically indicated to be excluded, provide all required conduit, boxes, wiring, <br />connectors, etc. as required for a complete operating system. <br />F.Comply with NEMA WC 70. <br />G.Conductor Material: <br />1.Provide copper conductors except where aluminum conductors are specifically indicated. <br />Substitution of aluminum conductors for copper is not permitted. Conductor sizes <br />indicated are based on copper unless specifically indicated as aluminum. Conductors <br />designated with the abbreviation "AL" indicate aluminum. <br />2.Copper Conductors: Soft drawn annealed, 98 percent conductivity, uncoated copper <br />conductors. <br />3.Aluminum Conductors (only where specifically indicated or permitted for substitution): <br />AA-8000 series aluminum alloy conductors. <br />H.Minimum Conductor Size: 12 AWG. <br />I.Maximum Conductor Size: 500 kcmil <br />J.Conductors for branch circuits shall be sized to prevent a voltage drop exceeding three percent <br />(3%) at the farthest outlet of power, heating and lighting loads, or any combination of such <br />loads. The maximum total voltage drop on both feeders and branch circuits to the farthest <br />outlet shall not exceed five percent (5%). <br />1.Where the branch circuit conductor length from the panel to the first outlet on a 277 volt <br />circuit exceeds 125 feet, the branch circuit conductors from the panel to the first outlet <br />shall not be smaller than #10 AWG. Increase the branch circuit conductor size an <br />additional wire size for reach 125’ of additional length of the entire circuit. The ground <br />conductor size shall be increased proportionately to the increase in the phase conductors <br />per 2017 NEC 250.122(B). <br />2.Where the conductor length from the panel to the first outlet on a 120 volt circuit exceeds <br />50 feet, the branch circuit conductors from the panel to the first outlet shall not be smaller <br />DocuSign Envelope ID: 09980A3B-0691-41B4-854D-3865F2287392
