17、n and Thermocouple Extension Conductor Identification This subject has been carried in ICEA publications over the years, dating back to the 1950s. It has been updated as necessitated by changes in the National Electrical Code. It has appeared in the main part of several standards, but later, in the

18、Appendices under designations K and E. Due to its widespread use, the complete text and tables have been reprinted in this convenient, stand-alone document; but the appendix letters K or E have been deleted. This information was included in now obsolete ICEA/NEMA standards S-19-81/WC3, S-61-402/WC5,

19、 S-66-524/WC7 and S-68-516/WC8. The conductor identification methods and sequence of colors now are only included in ICEA/NEMA Standard S-73-532/WC57.

25、fication of control, instrumentation and thermocouple extension cables when such identification is used. 2 NATIONAL ELECTRICAL CODE The National Electrical Code specifies that conductor colored white be used only as grounded conductors and that conductors colored green or green/yellow be used only a

26、s grounding conductors and that neither white nor green be used in any manner on ungrounded conductors. Tables 2 and 4 provide color sequences that do not include white or green conductors. If grounded or grounding conductors, or both, are used in the cable, they shall be colored white or green resp

27、ectively, and inserted as the second or third, or both, designated conductor in the first sequence of circuit identification only. Where these conductors are required, they shall be specified. 3 METHODS OF CIRCUIT IDENTIFICATION 3.1 Method 1Colored Compounds with Tracers This method uses base colors

28、 with tracers in accordance with Table 1 or 2. These color combinations shall be repeated in regular sequence as necessary. Base and tracer colors shall be recognizably the color combinations given in the tables and should approximately match the color shades given in Table 6. Base colors may be obt

29、ained by suitable color coatings applied to the insulation or jacket surface or by colored insulation or jacket compound. Tracers shall be colored stripes or bands marked on the surface of the insulation or jacket in such a manner as to afford distinctive circuit coding throughout the length of each

30、 wire. Tracers may be continuous or broken lines, such as series of dots or dashes, and shall be applied longitudinally, annularly, spirally, or in other distinctive patterns. 3.2 Method 2Neutral Colored Compounds with Tracers This method uses a neutral background or base color, such as tan, on all

31、conductors, with tracers as defined in Method 1 and in accordance with Table 3 or 4. These color combinations shall be repeated in regular sequence as necessary. 3.3 Method 3Neutral or Single-Color Compounds with Surface Printing of Numbers and Color Designations or Only Color Designations This meth

32、od uses a single-color insulation or covering on all conductors with printed conductor numbers and color designations or only color designations in accordance with Table 1 or 2. These color combinations shall be repeated in regular sequence as necessary. 1 ICEA S-58-679-2014 For example, using Table

33、 2 for conductors 1 to 3, inclusive: 1 - Black 1 - Black 1 - Black, and such 2 - Red 2 - Red 2 - Red, and such 3 - Blue 3 - Blue 3 - Blue, and such NOTEWhen color only designation is used, numbers are deleted 3.4 Method 4Neutral or Single-Color Compounds with Surface Printing of Numbers Control Cabl

34、e only This method uses a single color insulation or covering on all conductors with each conductor numbered in sequence by surface printing, beginning with the number 1. 3.5 Method 5Individual Color Coding with Braids This method uses colored braids over the insulated conductors in accordance with

35、Table 2 or 5. The shades of the colors should approximately match those identified by the number given in Table 6. (This paragraph has been approved by NEMA as Authorized Engineering Information.) Color sequence shall begin with black on the inside. When more than one color is required, the first co

36、lor named in the tables shall be the background color. The tracers shall consist of three carriers with each carrier composed of a minimum of two ends. Where two tracers are used, they shall be crossed. 3.6 Method 6Layer Identification This method uses a distinctively identified conductor in each la

37、yer for control cables having braidless or jacketed individual conductors requiring layer-tracer identification. One conductor in each layer of the cable shall be covered by a braid or tape, or shall be provided with a raised ridge or ridges to function as a tracer, or be otherwise distinctively mar

38、ked or colored. 3.7 Method 7Silicone Rubber Insulated Cables When circuit identification is required for silicone rubber insulated cables (including pairs), it shall be by means of colored braids. The color sequence shall be in accordance with Table 7. For cables composed of more than 16 conductors,

39、 these 16 color combinations shall be repeated in regular sequence to the extent necessary to provide such identification of all conductors. When more than one color is required, the first color named in the table shall be the background color. The shades of the colors shall approximately match thos

40、e identified by the numbers given in Table 6. The tracers shall consist of three carriers with each carrier composed of a minimum of two ends. When two tracers are used, they shall be crossed. 3.8 Methods 8, 8A and 8B Paired Conductors Neutral or Single Color Compounds with Surface Printing of Numbe

41、r and Color Designations This method uses a single-color insulation or covering on all conductors with printed conductor numbers and color designations. One conductor of each pair should be printed “1-black” or “2-white.” The sequence for coding the “other” conductor of each pair should be in accord

42、ance with Tables 1 or 2, omitting 1-black or 2-white for Methods 8 and 8B or omitting 1-black for Method 8A. For example: 2 ICEA S-58-679-2014 (a) (b) (c) Print 1st pair 1-black, or 2-white, or 1-black, 2-white 1-black 3-blue Print 2nd pair 1-black, or 2-white, or 1-black, 3-red 3-red 4-orange Print

43、 3rd pair 1-black, or 2-white, or 1-black, 4-green 4-green 5-yellow Print 4th pair 1-black, or 2-white, or 1-black, 5-orange 5-orange 6-brown 3.8.1 Method 8 This method uses a single-color insulation or covering on all conductors with printed conductor numbers and color designations as described in

44、examples (a) and (b) for the first 20 pair in accordance with Table 1. For cables composed of more than 20 pairs, these 20 color combinations should be repeated in regular sequence to the extent necessary to provide identification of all pairs. 3.8.2 Method 8A This method uses a single-color insulat

45、ion or covering on all conductors with printed conductor numbers and color designations as described in example (c) for the first 35 pairs in accordance with Table 2. For cables composed of more than 35 pairs, these 35 color combinations should be repeated in regular sequence to the extent necessary

46、 to provide identification of all pairs. 3.8.3 Method 8B This method uses a single-color insulation or covering on all conductors with printed conductor numbers and color designations as described in examples (a) and (b) in accordance with Table 1 using color combinations in non-repeating sequence t

47、o the extent necessary to provide identification of all pairs. 3.9 Methods 9 and 9A Colored Compounds With Numbers Paired Conductors One conductor on each pair should be coded “white” or “black” and the other conductor in each pair should be coded with any other contrasting color. 3.9.1 Method 9 One

48、 conductor of each pair should be coded “white” or “black” and the other conductor should be coded with any other contrasting color. Pairs should be identified in sequence by printed numbers on at least one conductor in each pair, beginning with the number 1. 3.9.2 Method 9A One conductor of each pa

49、ir should be coded “white” or “black” and the other conductor should be coded with any other contrasting color. Pairs should be identified in sequence by printed numbers on the jacket or covering over each pair, beginning with the number 1. 3 ICEA S-58-679-2014 4 THERMOCOUPLE EXTENSION CABLES Color coding of pairs should be in accordance with ANSI MC 96.1. Colors should approximately, but need not necessarily exactly, match the color shades specified in Table 8. 4.1 Methods 10 and 10A Color Coding of Braidless
