scope:

This specification covers single and multiple conductor cables and wires employing soft-annealed copper or copper clad aluminum conductors, 1350 aluminum and 8000-series aluminum alloys conductors, insulated with rubber, thermoplastic, cross-linked-polyethylene, ethylene propylene rubber, chlorosulphonated polyetheylene, varnished cloth. They are intended to be used for transmission of power in fixed type installations; also for special purpose applications (e.g. control) when appropriate.

Cable and wire furnished under this specification shall be of the types specified in table I.

Cables and wires covered by this specification shall be identified by a type designation, formed as indicated below. This type designation is intended for cataloging and ordering purposes, and not for surface printing on the wire or cable.

The UL (Underwriters' Laboratories) type designation shall consist of the types specified in 1.2.1.

The maximum working voltage shall be designated as follows:

03 - for use at not more than 300 volts. 06 - for use at not more than 600 volts. 10 - for use at not more than 1000 volts. 20 - for use at not more than 2000 volts. 30 - for use at not more than 3000 volts. 40 - for use at not more than 4000 volts. 50 - for use at not more than 5000 volts.

The conductor material shall be designated as follows:

A - 1350 aluminum C - copper. CA - copper clad aluminum (UL 83) AA - aluminum alloy, 8000 series (UL 83, 44, 493, 854)

The type of conductor(s) shall be designated as follows:

E - Solid conductor (AWG 20 to AWG 8 only). F - Concentric-lay-stranded conductor(s) of standard flexibility, conforming to type C. class B of QQ-W-343 or class B of American Society for Testing and Materials Document ASTM-B231, as applicable. G - Concentric-lay-stranded conductor(s) where greater flexibility is desired, conforming to type C, class C of QQ-W-343 or class C of ASTM-B231 as applicable. H - Rope-lay-stranded conductor(s) where extreme flexibility is desired, conforming to type RC, class G of QQ-W-343. J - Rope-lay-stranded conductor(s) where extreme flexibility is desired, conforming to type RC, class H of QQ-W-343. K - Bunch-stranded conductor(s) where extreme flexibility in the smaller AWG sizes is desired, conforming to type B, class K of QQ-W-343. L - Compact stranded conductor(s) where greater flexibility is desired, conforming to Class B of ASTM B400.

The number of individual conductors of the same wire size shall be designated by that number followed by a slant line and followed by a number indicating the conductor AWG size. When cables are made up of different wire sizes, each different wire size with the number of conductors shall be individually represented, with a dash separating each different wire size. A conductor larger than No. 0000 AWG shall be designated by its cross-sectional area in circular mils.

The type of insulation shall be designated as follows:

SR - synthetic rubber T - thermoplastic XP - cross linked polyethylene CP - chlorosulfonated polyethylene V - varnished cloth EP - Ethylenepropylene

The outer covering shall be designated as follows:

SJ - synthetic rubber jacket NJ - neoprene jacket TJ - thermoplastic jacket PJ - polyamide jacket XP - cross linked polyethylene jacket CB - cotton braid GB - glass braid FC - fibrous covering LS - lead sheath AL - aluminum sheath AR - armored UJ - unjacketed CPE - chlorinated polyethylene

When a ground wire is part of a cable configuration, it shall be designated by the letter "G".

The color code for single conductor cables and wires shall be designated by the appropriate identifying number as shown in table II. (See 3.3.1.) TABLE II. Color-code identification for single conductor cables and wires

Number Color Number Color designator designator ----------------------------------------------------- 0 Black 5 Green 1 Brown 6 Blue 2 Red 7 Violet (purple) 3 Orange 8 Gray (slate) 4 Yellow 9 White NOTE: This table is not intended to signify a color sequence but only a number-color identification reference.

For 2-, 3-, and 4-conductor cables designation of color-coding will not be necessary in the type designation (see 1.2.2 and 1.2.12). These multi-conductors have a definite color-coding arrangement (see 3.3.2); consequently, the number of multi-conductors in the type designation (see 1.2.8) automatically signifies the color-code.
