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 ...
The standard includes preferred current ratings and wire gauges for both International (deemed Series I) and North American (deemed Series II) applications. Series I preferred current ratings (in amps) are: 16, 32, 63, 125, 250, 400, 630 and 800, with wire gauges specified as mm 2 .
A single insulated conductor in free air has 70 A rating. Ampacity rating is normally for continuous current, and short periods of overcurrent occur without harm in most cabling systems. Electrical code rules will give ratings for wiring where short-term loads are present, for example, in a hoisting motor.
An electrical cable is an assembly of one or more wires running side by side or bundled, which is used as an electrical conductor to carry electric current. Electrical cables are used to connect two or more devices, enabling the transfer of electrical signals, power, or both from one device to the other. Physically, an electrical cable is an ...
IEC 60055 Paper-insulated metal-sheathed cables for rated voltages up to 18/30 kV (with copper or aluminium conductors and excluding gas-pressure and oil-filled cables) IEC 60059 IEC standard current ratings; IEC 60060 High-voltage test techniques; IEC 60061 Lamp caps and holders together with gauges for the control of interchangeability and safety

Wire that is approved to BS 6231 might not carry the UL and CSA ratings, if, for example, the wire is not suitable for use at the higher 105 °C temperature that is specified for those ratings. In that case, the wire is not tri-rated. According to UL 758, the maximum operating temperature of tri-rated cable is 105 °C. British Standard BS 6231 ...
