DocuSign Envelope ID: B94F2D40-3B3C-47A7-86C2-6F1 B4F92C62C <br /> Orange County Emergency Services Building Construction Documents <br /> B. Verify that work likely to damage wire and cable has been completed. <br /> C. Verify that raceways, boxes, and equipment enclosures are installed and are properly sized to <br /> accommodate conductors and cables in accordance with NFPA 70. <br /> D. Verify that field measurements are as indicated. <br /> E. Verify that conditions are satisfactory for installation prior to starting work. <br /> 3.02 PREPARATION <br /> A. Clean raceways thoroughly to remove foreign materials before installing conductors and cables. <br /> 3.03 INSTALLATION <br /> A. Circuiting Requirements: <br /> 1. Unless dimensioned, circuit routing indicated is diagrammatic. <br /> 2. When circuit destination is indicated without specific routing, determine exact routing required. <br /> 3. Arrange circuiting to minimize splices. <br /> 4. Include circuit lengths required to install connected devices within 10 ft of location indicated. <br /> 5. Maintain separation of Class 1, Class 2, and Class 3 remote-control, signaling, and <br /> power-limited circuits in accordance with NFPA 70. <br /> 6. Maintain separation of wiring for emergency systems in accordance with NFPA 70. <br /> 7. Circuiting Adjustments: Unless otherwise indicated, when branch circuits are indicated as <br /> separate, combining them together in a single raceway is not permitted. <br /> 8. Common Neutrals: Unless otherwise indicated, sharing of neutral/grounded conductors <br /> among up to three single phase branch circuits of different phases installed in the same <br /> raceway is not permitted. Provide dedicated neutral/grounded conductor for each individual <br /> branch circuit. <br /> B. Install products in accordance with manufacturer's instructions. <br /> C. Perform work in accordance with NECA 1 (general workmanship). <br /> D. Install metal-clad cable (Type MC) in accordance with NECA 120. <br /> E. Installation in Raceway: <br /> 1. Tape ends of conductors and cables to prevent infiltration of moisture and other <br /> contaminants. <br /> 2. Pull all conductors and cables together into raceway at same time. <br /> 3. Do not damage conductors and cables or exceed manufacturer's recommended maximum <br /> pulling tension and sidewall pressure. <br /> 4. Use suitable wire pulling lubricant where necessary, except when lubricant is not <br /> recommended by the manufacturer. <br /> F. Paralleled Conductors: Install conductors of the same length and terminate in the same manner. <br /> G. Secure and support conductors and cables in accordance with NFPA 70 using suitable supports <br /> and methods approved by the authority having jurisdiction. Provide independent support from <br /> building structure. Do not provide support from raceways, piping, ductwork, or other systems. <br /> H. Terminate cables using suitable fittings. <br /> 1. Metal-Clad Cable (Type MC): <br /> a. Use listed fittings. <br /> b. Cut cable armor only using specialized tools to prevent damaging conductors or <br /> insulation. Do not use hacksaw or wire cutters to cut armor. <br /> I. Install conductors with a minimum of 12 inches of slack at each outlet. <br /> J. Neatly train and bundle conductors inside boxes, wireways, panelboards and other equipment <br /> enclosures. <br /> K. Group or otherwise identify neutral/grounded conductors with associated ungrounded conductors <br /> inside enclosures in accordance with NFPA 70. <br /> L. Make wiring connections using specified wiring connectors. <br /> 1. Make splices and taps only in accessible boxes. Do not pull splices into raceways or make <br /> splices in conduit bodies or wiring gutters. <br /> PDC Project 18102 LOW-VOLTAGE ELECTRICAL 26 05 19- 6 <br /> 12/17/2018 POWER CONDUCTORS AND <br /> CABLES <br />
