ORANGE COUNTY 260519-4 <br /> <br />Emergency Management Warehouse Building Dehumidification Secondary Voltage Wires and Cables <br /> <br /> <br /> <br />Pull conductors simultaneously where more than one is being installed in same raceway. 1 <br /> 2 <br />Use pulling compound or lubricant, where necessary; compound used must not deteriorate conductor or insulation. 3 <br />After conductors have been pulled, clean exposed conductors and surrounding area to remove all evidence of the 4 <br />use of pulling compound. 5 <br /> 6 <br />Use pulling means including fish tape, cable, rope and basket weave wire/cable grips that will not damage cables or 7 <br />raceway. 8 <br /> 9 <br />Keep conductor splices to a minimum. 10 <br /> 11 <br />Install splices and taps that possess equivalent or better mechanical strength and insulation ratings than conductors 12 <br />being spliced. 13 <br /> 14 <br />Use splice and tap connectors that are compatible with conductor material. 15 <br /> 16 <br />Tighten electrical connectors and terminals, including screws and bolts, in accordance with manufacturer's published 17 <br />torque tightening values. Where manufacturer's torque requirements are not indicated, tighten connectors and 18 <br />terminals to comply with tightening torques specified in UL Standard 486A and B. 19 <br /> 20 <br /> 21 <br />WIRING CONNECTIONS AND TERMINATIONS 22 <br /> 23 <br />Splices shall be permitted on conductors up to #4 AWG. No splices shall be permitted on conductor #3 AWG and 24 <br />larger without specific approval in writing by the A-E. Splices shall be made in accessible junction boxes; no splices 25 <br />shall be made in conduit bodies. 26 <br /> 27 <br />Splices, taps, and attachments of fittings and lugs shall be electrically and mechanically secure. Connectors and lugs 28 <br />shall be proper size and labeled as suitable for the number and type of conductors joined. 29 <br /> 30 <br />Solid conductors, namely those sized #10 and #12 AWG copper shall be spliced or tapped only by the use of Ideal 31 <br />"Wing-Nuts" or "Wire Nuts", Buchanan's "B-Cap" or 3M Co.'s "Scotchlox" connectors. "Sta-Kon" or other permanent 32 <br />type crimp connectors shall not be used. 33 <br /> 34 <br />Self-stripping electrical pigtail and tap connectors shall not be used. 35 <br /> 36 <br />Stranded conductors, namely #8 AWG to #4 AWG, shall be spliced or tapped by approved mechanical connectors. 37 <br />Insulation for splices or taps shall be obtained by the use of Listed insulating covers designed for use with the 38 <br />particular connector. Quality of insulation at splices shall equal that of the conductor insulation in terms of 39 <br />temperature resistance, covering ability and durability. 40 <br /> 41 <br />Conductors, in all cases, shall be continuous from outlet to outlet, and no splicing shall be made except within outlet 42 <br />or junction boxes, troughs, and gutters. No splices shall be permitted in panel enclosures, disconnects or utilization 43 <br />equipment. 44 <br /> 45 <br />Lugs for conductors #8 through #4 AWG shall be copper, with a direct acting screw. Where permitted, lugs for 46 <br />conductors #3 AWG and larger shall be copper, applied directly to the cable by hydraulic pressure. Lugs shall not be 47 <br />split bolt or screw types. 48 <br /> 49 <br />Tape, where used, shall be made using special oil resistant vinyl plastic tape that is Listed, rated 105 C. 50 <br /> 51 <br />Splices or taps in grounding conductors (where permitted) in sizes #8 AWG and larger shall be by means of 52 <br />exothermic welding and termination shall be by means of approved grounding connectors. As an alternate, 53 <br />connectors using hydraulic compression tools may be used as a contractor selection option. Solder shall not be used 54 <br />as a means of joining grounding conductors. 55 <br /> 56 <br />Thoroughly clean wires before installing lugs and connectors. 57 <br /> 58 <br />Make splices, taps and terminations to carry full ampacity of conductors without perceptible temperature rise. 59 <br /> 60 <br />DocuSign Envelope ID: 7668B866-6C26-485C-9A45-DAAB5D4BD951
