For example, the United States National Electrical Code, Table 310.15(B)(16), specifies that up to three 8 AWG copper wires having a common insulating material (THWN) in a raceway, cable, or direct burial has an ampacity of 50 A when the ambient air is 30 °C, the conductor surface temperature allowed to be 75 °C. A single insulated conductor ...
A standard wire gauge. American Wire Gauge (AWG) ... The cross-sectional area of each gauge is an important factor for determining its current-carrying capacity.
Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...
Current-carrying capacity, determining the cross-sectional size of the conductor(s); Environmental conditions such as temperature, water, chemical or sunlight exposure, and mechanical impact, determining the form and composition of the outer cable jacket.
The cross sectional area of an aluminium conductor must be 56% larger than copper for the same current carrying capability. The need to increase the thickness of aluminium wire restricts its use in many applications, [ 4 ] such as in small motors and automobiles.
Conductor sizes range from 12 mm 2 (#6 American wire gauge) to 1,092 mm 2 (2,156,000 circular mils area), with varying resistance and current-carrying capacity. For large conductors (more than a few centimetres in diameter), much of the current flow is concentrated near the surface due to the skin effect. The center of the conductor carries ...
The total current carried in all three wires (including the neutral) will always be twice the supply current of the most heavily loaded half. For short wiring runs limited by conductor current carrying capacity , this allows three half-sized conductors to be substituted for two full-sized ones, using 75% of the copper of an equivalent single ...
One important property of the insulation which affects the current-carrying capacity of the wire is the maximum conductor temperature. This, in combination with the ambient temperature and ability of the environment to absorb heat, determines the amount of tolerable copper loss in the wire, and therefore its size in relation to the load current ...
