Also, the size of the aluminum wire needs to be larger compared to copper wire used for the same circuit due to the increased resistance of the aluminum alloys. For example, a 15 A branch circuit supplying standard lighting fixtures can be installed with either #14 AWG copper building wire or #12 AWG aluminum building wire according to the NEC ...
Sizes with multiple zeros are successively thicker than 0 AWG and can be denoted using "number of zeros/0", for example 4/0 AWG for 0000 AWG. For an m /0 AWG wire, use n = −(m − 1) = 1 − m in the above formulas. For instance, for 0000 AWG or 4/0 AWG, use n = −3.
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
A 0000 AWG solid wire is defined to have a diameter of exactly 0.46 inches (11.68 mm). The cross-sectional area of this wire is: ... For example, 0000 AWG (4/0 ...
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 Solid aluminium conductors were originally made in the 1960s from a utility-grade aluminium alloy that had undesirable properties for a building wire, and were ...
Sample cross-section of high tension power (pylon) line, showing 1 strand (7 wires) of steel surrounded by 4 concentric layers of aluminium. Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines.
