INSULATED CONDUCTORS Section 16070 15-1207 1. Twist together #10 AWG or smaller wiring, electrically and mechanically strong, and insulate with insulated electrical spring connectors, Scotchlok, Ideal or equal. Threaded type wire nuts are not acceptable. 2. Make joints and connections for #8 AWG or larger with solderless tool applied pressure lugs and connectors. Insulate with layers of plastic tape equal to inslation of wire and with all irregular surfaces properly padded with "Scotchfil" putty prior to application of tape for uninsulated lugs and wire ends. 3. Install feeder cables in one (1) continuous length unless splices are approved by the electrical engineer of record. Where permitted, make feeder splicing with high compression sleeve type connector followed by a heavy wall heat shrink tubing, UL approved for direct burial per UL 786D, Thomas & Betts, Series HS or equal. 4. Where oversized cables are used to accommodate voltage drop, whether a single or parallel feeder, provide appropriate reducing adapter and conductors for termination. B. Install wires or pull line in conduit and furnish all equipment and material required to complete installation. Install all wire connectors where required, cable supports, tape and insulating materials, or any other item of material and equipment to properly install wires and cables. C. Install all termination lugs used to connect conductors to terminal blocks with ratchet type crimping tool as recommended by manufacturer of connector. No spade -type lugs will be permitted. All work shall be in accordance with 2013 California Electrical Code unless otherwise directed or specified herein. D. Pull cable into conduit with sufficient length left at ends of cable to make connections conveniently to all equipment or devices. Do not pull wire and cable into conduit until conduit runs are swabbed clean and free from obstructions, sharp corners and inspected for pulling by Project Coordinator. Install wire and cable so there will be no cuts or abrasions in insulation or protective covering or kinks in conductors. Make no splices in conductors except where devices are supplied with internal leads. Make splices in nearest condulet or junction box or, where devices are physically too small to accept scheduled wires and associated lugs, splices may be made in nearest condulet or junction box with minimum No. 16 AWG size wire. E. Install all cables in straight and orderly arrangement with no interlacing. Take care to avoid sharply bending or kinking conductor, damaging insulation or stressing cable beyond manufacturer's recommendations during pulling. Protect cable from absorption of moisture during storage, before pulling and after pulling. F. Cable attachment for pulling shall be of patent cable grips. Difficult pulling is not anticipated. However, maximum pull tension shall not exceed manufacturer's recommended value for cable being measured with tension dynometer. Use pulling compound approved by cable manufacturer to facilitate pulling of cables. Cable pulling to be witnessed by Project Coordinator. Notify Project Coordinator in reasonable amount of time before pull begins. G. Form cable to avoid sharp bends over edges of conduit bushings upon entering or leaving boxes or cabinets and to avoid bearing against edges of enclosures and supports when entering or leaving enclosures. Neatly cable or clamp conductors using nylon "ty-raps". H. In installation of power cables which are single conductors, form Phases A, B, and C in pyramid method in order to keep circuits together. 3
