City of Everett 26 05 26 - 8 <br /> Inductive Charging Infrastructure for Everett Transit <br /> a. Permanent Generators: Install grounding electrode(s) at location of <br /> permanent generators having switched neutral connections. Electrode <br /> must be connected to equipment grounding conductor and to frame of <br /> generator. <br /> 6. Grounding Underground Distribution System Components: <br /> a. Duct-Bank Grounding Conductor: Bury 12 inches above duct bank when <br /> indicated as part of duct-bank installation. <br /> b. Comply with IEEE C2 grounding requirements. <br /> c. Grounding Manholes and Handholes: Install driven ground rod through <br /> manhole or handhole floor, close to wall, and set rod depth so 4 inches will <br /> extend above finished floor. If necessary, install ground rod before manhole <br /> is placed and provide 1/0 AWG bare, tinned-copper conductor from ground <br /> rod into manhole through waterproof sleeve in manhole wall. Protect <br /> ground rods passing through concrete floor with double wrapping of <br /> pressure-sensitive insulating tape or heat-shrunk insulating sleeve from <br /> 2 inches above to 6 inches below concrete. Seal floor opening with <br /> waterproof, non-shrink grout. <br /> d. Grounding Connections to Manhole Components: Bond exposed-metal <br /> parts such as inserts, cable racks, pulling irons, ladders, and cable shields <br /> within each manhole or handhole, to ground rod or grounding conductor. <br /> Make connections with 4 AWG minimum, stranded, hard-drawn copper <br /> bonding conductor. Train conductors level or plumb around corners and <br /> fasten to manhole walls. Connect to cable armor and cable shields in <br /> accordance with manufacturer's published instructions with splicing and <br /> termination kits. <br /> e. Pad-Mounted Transformers and Switches: Install two ground rods and ring <br /> electrode around pad. Ground pad-mounted equipment and noncurrent- <br /> carrying metal items associated with substations by connecting them to <br /> underground cable and grounding electrodes. Install tinned-copper <br /> conductor not less than 2 AWG for ring electrode and for taps to equipment <br /> grounding terminals. Bury ring electrode not less than 6 inches from <br /> foundation. <br /> 7. Equipment Grounding and Bonding: <br /> a. Install insulated equipment grounding conductors with feeders and branch <br /> circuits. <br /> b. Install insulated equipment grounding conductors with the following items, <br /> in addition to those required by NFPA 70: <br /> 1) Feeders and branch circuits. <br /> c. . <br /> 3.4 FIELD QUALITY CONTROL FOR GROUNDING AND BONDING <br /> A. Acceptance Testing Preparation: <br /> B. Field tests and inspections must be witnessed by Owner's representative. <br /> C. Tests and Inspections: <br /> 26 05 26 - 8 GROUNDING AND BONDING FOR ELECTRICAL SYSTEMS <br />
