Standard Practice for Selection of Wire and Cable Size in AWG or Metric Units

SIGNIFICANCE AND USE
The selection criteria is to be applied for uses of (1) new cable and (2) replacement cable.
For the selection of new cable or the selection of replacement cable, this practice defines the choice criteria for conductor selection for cables in AWG (ASTM) or metric (IEC) sizes.
SCOPE
1.1 This practice is intended as a guide to shipbuilders, shipowners, and design agents for use in the selection of conductor size for single conductor or multiple conductor cable sizes either in American Wire Gauge (AWG) or metric designations for commercial ship design and construction.  
1.2 The comparison chart of electrical conductor sizes shown in Table 1 presents a combined listing of international standard sizes of annealed copper conductors in accordance with AWG (Specification B 8) English units or IEC (IEC 228) metric units.  
1.3 As a precautionary caveat, some conductor sizes listed in Table 1 may exceed minimal size requirements of the U.S. Coast Guard, the American Bureau of Shipping, and IEEE STD 45 for specific applications  
1.4 The values stated for ampacity and dc resistance are presented as typical values and are provided for information only.
