    1. 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.

    (A) The inch diameters, square inch areas, and circular mil areas are rounded values calculated from the metric diameters.
