2. American wire gauge - Wikipedia

   en.wikipedia.org/wiki/American_wire_gauge

   The resistance of copper wire is approximately ⁠ 1 ohms / 1000 feet ⁠ for 10 AWG, ⁠ 10 ohms / 1000 feet ⁠ for 20 AWG, ⁠ 100 ohms / 1000 feet ⁠ for 30 AWG, and so on. [ 5 ] : 27 Because aluminum wire has a conductivity of approximately 61% of copper, an aluminum wire has nearly the same resistance as a copper wire that is two sizes ...

3. IEC 60228 - Wikipedia

   en.wikipedia.org/wiki/IEC_60228

   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 ...

   IEC 60228, the metric wire-size standard used in most parts of the world. Circular mil, Electrical industry standard for wires larger than 4/0. American Wire Gauge (AWG), used primarily in the US and Canada; Standard Wire Gauge (SWG), the British imperial standard BS3737; Jewelry wire gauge; Body jewelry sizes

5. Electrical wiring - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring

   For instance, instead of 14 AWG (American wire gauge) copper wire, aluminium wiring would need to be 12 AWG on a typical 15 ampere lighting circuit, though local building codes vary. Solid aluminium conductors were originally made in the 1960s from a utility-grade aluminium alloy that had undesirable properties for a building wire, and were ...

   en.wikipedia.org/wiki/Direct-buried_cable

   Cross-section of direct buried cable. Direct-buried cable (DBC) is a kind of communications or transmissions electrical cable which is especially designed to be buried under the ground without any other cover, sheath, or duct to protect it. [1] Most direct-buried cable is built to specific tolerances to heat, moisture, conductivity, and soil ...
