AWG is colloquially referred to as gauge and the zeros in thick wire sizes are referred to as aught / ˈ ɔː t /. Wire sized 1 AWG is referred to as "one gauge" or "No. 1" wire; similarly, thinner sizes are pronounced "x gauge" or "No. x" wire, where x is the positive-integer AWG number. Consecutive AWG wire sizes thicker than No. 1 wire are ...
Ampacity is a portmanteau for ampere capacity, defined by United States National Electrical Codes. Ampacity is defined as the maximum current, in amperes, that a ...
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 ...
Each notch is stamped with a number, and the wire or sheet, which just fits a given notch, is stated to be of, say, No. 10, 11, 12, etc., of the wire gauge. The circular forms of wire gauge measurement devices are the most popular, and are generally 3 + 3 ⁄ 4 inches (95 mm) in diameter, with thirty-six notches; many have the decimal ...
In both those instances the white wire should be identified as being hot, usually with black tape inside junction boxes. The neutral wire is identified by gray or white insulated wire, perhaps using stripes or markings. With lamp cord wire the ribbed wire is the neutral, and the smooth wire is the hot. NEC 2008 400.22(f) allows surface marking ...
minimum 14 gauge wire, solid for 15 amp circuits (some local codes require a minimum of 12 gauge for 15 amp circuits, except for switch legs - that is, circuit portions that are strictly between a light switch and the light that it serves; stranded may also be used, and is of greater ampacity, but is more expensive and requires slightly ...
Each size of wire in the American Wire Gauge is related to its neighboring wire sizes by the ratio 1.122932. (See footnote for the derivation of this value). For example, 0 (zero) gauge wire has a diameter of 0.3249 inches and the next smaller wire (1 gauge) has a diamter of 0.3249 / 1.122932 ~= 0.2893 inches.
