ELECTRICAL WORK, GENERAL <br />REQUIREMENTS <br />Section 16000 <br />15-1207 <br />property of the Owner. Such salvaged materials and equipment shall be delivered to the Owner <br />on the premises as directed and shall be neatly piled or stored and protected from damage. <br />B. All materials considered to be scrap and not salvable shall be removed from the premises and <br />disposed of by the Contractor. <br />3.7 GROUNDING: <br />A. Ground Fittings: Approved manufactured type, installed and connected in accordance with <br />Code requirement; UL 467. <br />B. Ground neutral bus and non -current -carrying parts of equipment at each installation in <br />accordance with applicable Codes. Ground Conductor: Copper having a current capacity in <br />accordance with 2013 C.E.C. and Electrical Safety Orders, but not smaller than #6 AWG. <br />C. Exercise every precaution to obtain good contact at all panelboards, outlets, and similar items. <br />Where it is not possible to obtain good contact, bond conduits around boxes with an insulated <br />conductor, #6 AWG minimum, connected to conduit by means of approved clamps. <br />D. Completely ground all equipment cases, motor frames, and other items to be grounded in <br />accordance with requirements of 2013 C.E.C. Install bond wire in flexible conduit. Install copper <br />bond wire, sized in accordance with 2013 C.E.C., in all non-metallic raceways and bond to all <br />metallic parts using approved fittings. Bond Wire: Copper. <br />E. Provide a ground resistance of five (5) ohms maximum. Measure ground resistance in normally <br />dry conditions not less than forty-eight (48) hours after rainfall. <br />F. Connect service ground conductor to metallic cold water pipe (pipe must be in contact with earth <br />for ten feet [10] or more and electrically continuous to point of connection of ground electrode <br />conductor). Additional ground electrode shall supplement the water ground. Bond building steel <br />to ground system. <br />G. Where the specified ground resistance cannot be met, install additional ground rods or radial <br />extensions of counterpoise ground wire until specified resistance is obtained. Rods shall be <br />three-quarter (3/4") diameter by ten feet (10') long copper -clad stell. <br />H. Space ground rods as evenly as possible at least ten feet (10') apart (fifteen feet [15] preferred) <br />and connect two feet (2') below ground. <br />Radial extension of counterpoise ground wire minimum length and depth of trench twenty-five <br />feet (25') by one and one-half feet (1 1/2"). <br />END OF SECTION <br />15 <br />
