ORANGE COUNTY 260519-3 <br /> <br />Emergency Management Warehouse Building Dehumidification Secondary Voltage Wires and Cables <br /> <br /> <br /> <br />Increase Drawing indicated size of conductors for voltage drop as follows: 1 <br /> 2 <br />Use #10 AWG conductor for 20 Ampere, 120 Volt branch circuit home runs longer than 50 feet, unless 3 <br />otherwise noted on Drawings. 4 <br /> 5 <br />Conduit runs shall contain the number of phase conductors shown on the plans. A dedicated neutral shall be 6 <br />installed for each phase conductor served by single pole, 120 Volt, 20 Amp circuit breakers. Multi-pole circuit 7 <br />breakers serving 120, 20 Amp multi-wire branch circuits with a common neutral shall not be permitted. Conduits runs 8 <br />shall contain related grounding and/or isolated grounding conductors. 9 <br /> 10 <br />Conduit runs that contain more than one neutral shall have each neutral conductor uniquely identified at 11 <br />each termination, splice and where routed through junction or pull boxes. Neutral conductors containing a 12 <br />factory applied, trace line along the length that matches the color of the associated phase conductor shall be 13 <br />used to meet this requirement. Machine printed labels with the panel and associated circuit number shall 14 <br />also be permitted for identifying neutral conductors. Colored tape and pre-printed tags shall not be 15 <br />acceptable. 16 <br /> 17 <br />Feeders and/or branch circuits shall not be combined either with each other or one with another into junction 18 <br />boxes, pull boxes, device boxes, manholes, or other common routing unless such routing is specifically 19 <br />indicated on the Drawings. 20 <br /> 21 <br />Neatly train wiring inside boxes, equipment and panelboards; Avoid bundling conductors with lacing or cable ties so 22 <br />that generated heat may be more easily dissipated. 23 <br /> 24 <br />Conduit runs indicated on the Drawings as composed of parallel runs of conductors shall be made identical with 25 <br />respect to length, conduit size, wire type, insulation type, routing, and terminations at each end. 26 <br /> 27 <br />Conductors Shall Be Color Coded as Follows: 28 <br /> 29 <br />Grounding Conductors: Green 30 <br /> 31 <br />Isolated Grounding Conductors: Green with yellow tracer 32 <br /> 33 <br />Grounded Neutral Conductors: White for 120 V systems 34 <br /> 35 <br />Ungrounded Phase Conductors for 208Y/120V Systems: Black (phase A), red (phase B), and blue (phase 36 <br />C) 37 <br /> 38 <br />Switch Leg Travelers: Violet 39 <br /> 40 <br /> Provide other wire colors as indicated on the Drawings. 41 <br /> 42 <br />Remarking of insulation colors by use of colored marker tape shall be permitted only as allowed by the NEC. 43 <br /> 44 <br />Install exposed cables (where permitted) parallel and perpendicular to surfaces, or exposed structural members. 45 <br />Cables shall follow surface contours, where possible. 46 <br /> 47 <br />Completely and thoroughly swab raceway system before installing conductors. 48 <br /> 49 <br />Branch circuit wiring shall not loop through receptacle terminals, but shall be connected by means of conductor taps 50 <br />joined to branch circuit conductors. At end of run, branch circuit conductors may terminate on receptacle screw 51 <br />terminals. Quick make, clamp, or push-in type terminations may not be used to make connections to devices. 52 <br /> 53 <br />Position all splices in pull boxes and junction boxes of adequate volume so they are accessible from the removable 54 <br />cover side of the box. 55 <br /> 56 <br />Conductors for signal systems shall be continuous (without splice) and shall be terminated on terminal strips or 57 <br />terminate in a manner approved by the system's manufacturer. 58 <br /> 59 <br />All neutrals and ground wires in panels shall be labeled with cloth wire markers to indicate the circuits being served. 60 <br />DocuSign Envelope ID: 7668B866-6C26-485C-9A45-DAAB5D4BD951
