Abstract
This specification prescribes the recommended standard metric sizes of solid round electrical conductors. The standard diameters of metric sizes of wires are preferred numbers calculated in accordance with the conventional mathematical principles. The standard metric size of stranded conductors and equivalent cross-sectional areas shall be designated.
Scope
1.1 This specification covers and prescribes the recommended standard metric sizes of solid round electrical conductors.
1.2 This specification prescribes the recommended standard metric size designations of stranded electrical conductors (see Explanatory Note 1).
Note 1: Physical properties, construction requirements, and manufacturing tolerances for specific products should be included in individual product specifications developed in accordance with appropriate sizes in this specification.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3.1 Exceptions—For conductor sizes designated by AWG or kcmil, the requirements in SI units have been numerically converted from corresponding values, stated or derived, in inch-pound units. For conductor sizes designated by SI units only, the requirements are stated or derived in SI units. Rounded values appear in Table 1.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
