The type designates the construction of the wire (see table I and 3.3). The following types are available (see 7.5): S - Solid single
9、strand. C - Concentric-lay-stranding. R - Rope-lay-bunched member stranding. E - Rope-lay-concentric member stranding. B - Bunch-stranding. H - Hookup conductor. 2.2 Class. The class defines the construction details within a particular type wire (see 7.2). Type S wires are classified as class S for
10、the purpose of this CID. 2.3 Temper. The available tempers per wire type are listed in table I (see 7.5). 2.4 Wire size. For solid wires of American Wire Gauge (AWG) 56 thru 0000 (4/0), the wire size is indicated by AWG size as specified in ASTM B258. For all wires larger than 4/0, the size is indic
11、ated by the cross sectional area in circular mils (thousandths of an inch). For sizes of stranded wires smaller than 250,000 circular mils, the AWG number that is the closest but larger in size is used except for hookup wire (type H), in which only even AWG numbers are used.
