Title:Montpelier District HeatingCity of Montpelier, VT16195 – Electrical IdentificationIssue Date:September 28, 2012Page #:4 of 5D. Identify Junction, Pull, and Connection Boxes: Coderequired caution sign forboxes shall be pressuresensitive, self adhesive label indicating system voltage inblack, preprinted on orange background. Install on outside of box cover. Alsolabel box covers with identity of contained circuits. Use pressuresensitive plasticlabels at exposed locations and similar labels or plasticized card stock tags atconcealed boxes.E. The following fieldapplied colorcoding methods may be used in lieu offactorycoded wire for sizes larger than No. 10 AWG.1. Apply colored, pressuresensitive plastic tape in halflapped turns for adistance of 6 inches from terminal points and in boxes where splices ortaps are made. Apply the last two laps of tape with no tension to preventpossible unwinding. Use 1inchwide tape in colors as specified. Do notobliterate cable identification markings by taping. Tape locations may beadjusted slightly to prevent such obliteration.2. In lieu of pressuresensitive tape, colored cable ties may be used for coloridentification. Apply three ties of specified color to each wire at eachterminal or splice point starting 3 inches from the terminal and spaced 3inches apart. Apply with a special tool or pliers, tighten for snug fit, andcut off excess length.F. Tag or label conductors as follows:1. Future Connections: Conductors indicated to be for future connection orconnection under another contract with identification indicating sourceand circuit numbers.2. Multiple Circuits: Where multiple branch circuits or control wiring orcommunications/signal conductors are present in the same box orenclosure (except for three circuit, fourwire home runs), label eachconductor or cable. Provide legend indicating source, voltage, circuitnumber, and phase for branch circuit wiring. Phase and voltage of branchcircuit wiring may be indicated by mean of coded color of conductorinsulation. For control and communications/signal wiring, use colorcoding or wire/cable marking tape at terminations and at intermediatelocations where conductors appear in wiring boxes, troughs, and controlcabinets. Use consistent letter/number conductor designations throughouton wire/cable marking tapes.3. Match identification markings with designations used in panelboards shopdrawings, Contract Documents, and similar previously establishedidentification schemes for the facility's electrical installations.ELECTRICAL IDENTIFICATION161954
