shall be placed in the ducts in a straight, neat and organized fashion and shall not be <br /> linked, tangled or twisted together. Additional wire ducting shall be provided for use <br /> by the electrical subcontractor for routing field wires to their landing points in the <br /> each electrical and instrumentation panel. <br /> J. Wiring not routed in duct work shall be neatly bundled, treed, and laced with plastic <br /> ties. Wiring across door hinges shall be carefully made up and supported to avoid <br /> straining and chafing of the conductors or from putting any strain on their terminals. <br /> K. TERMINATIONS: Single wire and cable conductors shall be terminated according to <br /> the requirements of the terminal device. All terminations must be made at terminals <br /> or terminal blocks. Use of spring or buttsplice connectors are not allowed. <br /> 1. Provide 2" minimum separation between wireway and terminal blocks. <br /> Installation of wireways too close to terminal blocks will be required to be <br /> completely reworked to the satisfaction of the Owner. <br /> 2. For captive screw pressure plate type terminals, the insulation shall be <br /> removed from the last 0.25 inches of the conductor. The conductors shall be <br /> inserted under the pressure plate to full length of the bare portion of the <br /> conductor and the pressure plate tightened without excess force. No more <br /> than two conductors shall be installed in a single terminal. All strands of the <br /> conductor shall be captured under the pressure plate. <br /> 3. For screw terminals, appropriately sized locking forked spade lugs shall be <br /> used. Lugs shall be crimp on type that form gas tight connections. All <br /> crimping shall be done using a calibrated crimping tool made specifically for <br /> the lug type and size being crimped. <br /> 4. On shielded cables, the drain wire shall be covered with insulating tubing <br /> along its full bare length between the cable jacket and the terminal lug or <br /> terminal pressure plate. <br /> 5. For sc ewless terminals, wire shall be stripped back and inserted per the <br /> manufacturer's instructions. When stripping insulation from conductors, do not <br /> score or otherwise damage conductor. <br /> 6. Heat shrink shall be placed on ends of shielded cable to cover foil. <br /> 7. Additional condulets with terminal blocks shall be supplied for wire termination <br /> to devices with leads instead of terminals. (i.e., solenoid valves, level probe, <br /> etc.), <br /> L. A ground bus shall be provided in each enclosure or cabinet. It shall have provisions <br /> for connecting a minimum of ten grounding conductors. Screw type lugs shall be <br /> provided for connection of grounding conductors.All grounding conductors shall be <br /> sized as shown on plans or in accordance with NEC Table 250-122, whichever is <br /> larger. <br /> M. Minimum wire bending space at terminals and minimum width of wiring gutters shall <br /> comply with NEC tables 373-6 (a) & (b). <br /> N. Future device and component mounting space shall be provided on the door, <br /> backpan, and subpanel where detailed on the Drawings. Where no detail is shown, <br /> provide a minimum of 15 percent usable future space. <br /> O. Doors shall swing freely and close with proper alignment. <br /> July 2007 Division III-214 NEI Phase II Water and Sewer <br /> CIP Nos. 7468, 7589, 7590 <br />
