Provide insulated equipment grounding conductor in each feeder and branch circuit raceway. <br /> Do not use raceways as sole equipment grounding conductor. <br /> 3. Where circuit conductor sizes are increased for voltage drop, increase size of equipment <br /> grounding conductor proportionally in accordance with NFPA 70. <br /> 4. Unless otherwise indicated, connect wiring device grounding terminal to branch circuit <br /> equipment grounding conductor and to outlet box with bonding jumper. <br /> 5. Terminate branch circuit equipment grounding conductors on solidly bonded equipment <br /> ground bus only. Do not terminate on neutral (grounded)or isolated/insulated ground bus. <br /> 6. Provide bonding jumper across expansion or expansion/deflection fittings provided to <br /> accommodate conduit movement. <br /> 2.02 GROUNDING AND BONDING COMPONENTS <br /> A. General Requirements: <br /> 1. Provide products listed, classified, and labeled as suitable for the purpose intended. <br /> 2. Provide products listed and labeled as complying with UL 467 where applicable. <br /> B. Conductors for Grounding and Bonding, in Addition to Requirements of Section 26 05 26: <br /> 1. Use insulated copper conductors unless otherwise indicated. <br /> C. Connectors for Grounding and Bonding: <br /> 1. Description: Connectors appropriate for the application and suitable for the conductors and <br /> items to be connected; listed and labeled as complying with UL 467. <br /> 2. Unless otherwise indicated, use exothermic welded connections for underground, concealed <br /> and other inaccessible connections. <br /> 3. Unless otherwise indicated, use mechanical connectors, compression connectors, or <br /> exothermic welded connections for accessible connections. <br /> 4. Manufacturers- Mechanical and Compression Connectors: <br /> a. Advanced Lightning Technology(ALT); : www.altfab.com/#sle. <br /> b. Burndy LLC; : www.burndy.com/#sle. <br /> c. Harger Lightning & Grounding; : www.harger.com/#sle. <br /> d. Thomas & Betts Corporation; www.tnb.com/#sle. <br /> PART 3 EXECUTION <br /> 3.01 EXAMINATION <br /> A. Verify that work likely to damage grounding and bonding system components has been completed. <br /> B. Verify that field measurements are as indicated. <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. Perform work in accordance with NECA 1 (general workmanship). <br /> C. Make grounding and bonding connections using specified connectors. <br /> 1. Remove appropriate amount of conductor insulation for making connections without cutting, <br /> nicking or damaging conductors. Do not remove conductor strands to facilitate insertion into <br /> connector. <br /> 2. Remove nonconductive paint, enamel, or similar coating at threads, contact points, and <br /> contact surfaces. <br /> 3. Exothermic Welds: Make connections using molds and weld material suitable for the items to <br /> be connected in accordance with manufacturer's recommendations. <br /> 4. Mechanical Connectors: Secure connections according to manufacturer's recommended <br /> torque settings. <br /> 5. Compression Connectors: Secure connections using manufacturer's recommended tools and <br /> dies. <br /> D. Identify grounding and bonding system components in accordance with Section 26 05 53. <br /> 3.03 FIELD QUALITY CONTROL <br /> A. Inspect and test in accordance with NETA ATS except Section 4. <br /> B. Perform inspections and tests listed in NETA ATS, Section 7.13. <br /> PDC Project 18102 GROUNDING AND BONDING 26 05 26- 2 <br /> 12/17/2018 FOR ELECTRICAL SYSTEMS <br />
