**American Wire Gauge (Awg) Versus Square Mm Cross Sectional Area** - A standard cord gauge. From wikipedia, the unfastened encyclopedia american wire gauge (awg), also referred to as the brown & sharpe twine gauge, is a standardized twine gauge gadget used in view that 1857 predominantly inside the united states for the diameters of spherical, solid, nonferrous, electrically conducting wire. [1] the cross-sectional region of every gauge is an essential thing for figuring out its modern-wearing capacity. The steel industry makes use of distinct cord gauges (as an example, w&m cord gauge or us steel twine gauge, or tune wire gauge). The table underneath does not practice to steel cord. Growing gauge numbers give decreasing wire diameters, which is much like many different non-metric gauging systems. This gauge device originated in the the variety of drawing operations used to produce a given gauge of cord. Very nice wire (as an example, 30 gauge) calls for greater passes via the drawing dies than does zero gauge twine. Producers of wire formerly had proprietary cord gauge systems; the development of standardized cord gauges rationalized choice of wire for a specific cause. The awg tables are for a unmarried, strong, round conductor. The awg of a stranded wire is determined by the whole cross-sectional location of the conductor, which determines its current-sporting capability and electric resistance. Because there also are small gaps between the strands, a stranded twine will constantly have a slightly large ordinary diameter than a stable wire with the identical awg. The awg size is one of the critical specs which might be printed on facts cables. As an example, an awg of 24 is commonplace for network cables consisting of a category five utp, and an awg of 26 is the norm for serial ata cables. Awg is also generally used to specify body piercing rings sizes, in particular smaller sizes. [2] contents 1 components 1.1 regulations of thumb 2 table of awg cord sizes 3 pronunciation four references 5 see also 6 outside links method by definition, no. 36 awg is 0.0.5 inches in diameter, and no. 0000 is zero.46 inches in diameter. The ratio of /american_wire_gauge 1 of 6 11/11/2008 8:forty five am these diameters is ninety two, and there are forty gauge sizes from no. 36 to no. 0000, or 39 steps. Using this commonplace ratio, cord gauge sizes range geometrically in line with the following components: the diameter of a no. N awg wire is or the gauge may be calculated from the diameter using [3] and the go-phase area is . Sizes with more than one zeros are successively larger than no. Zero and may be denoted the use of "variety of zeros/0", as an instance 4/zero for 0000. For an m/zero awg wire, use n = −(m−1) = 1−m within the above formulation. For instance, for no. 0000 or 4/0, use n = −three. The astm b 258-02 trendy defines the ratio between successive sizes to be the thirty ninth root of ninety two, or approximately 1.1229322. [4] astm b 258-02 additionally dictates that wire diameters have to be tabulated without a more than four good sized figures, with a resolution of no more than 0.0001 inches (0.1 mils) for wires larger than no. Forty four awg, and 0.00001 inches (0.01 mils) for wires no. 45 awg and smaller. Regulations of thumb the 6th electricity of this ratio may be very near 2, [5] which ends up in the subsequent rules of thumb: whilst the diameter of a twine is doubled, the awg will decrease through 6. (E.G. No. 2 awg is ready two times the diameter of no. 8 awg.) While the location of a twine is doubled, the awg will lower by way of three. (E.G. No. 14 awg wires have approximately the equal pass-sectional area as a single no. 11 awg twine.) Additionally, a decrease of ten gauge numbers, for example from no. 10 to 1/zero, multiplies the vicinity and weight by using approximately 10 and reduces the resistance by means of approximately 10. Desk of awg twine sizes the table under indicates numerous facts along with each the resistance of the numerous cord gauges and the allowable modern (ampacity) primarily based on plastic insulation. The diameter records in the table applies to strong wires. Stranded wires are calculated with the aid of calculating the equivalent cross sectional copper vicinity. The table underneath assumes dc, or ac frequencies identical to or less than 60 hz, and does no longer take skin impact under consideration. Turns of wire is on a nice-case state of affairs whilst winding tightly packed coils without a insulation. /American_wire_gauge 2 of 6 eleven/eleven/2008 8:forty five am awg diameter turns of cord location copper resistance [6] nec copper wire ampacity with 60/seventy five/ ninety°c insulation (a) [7] approximate stranded metric equivalents (inch) (mm) (per inch) (per cm) (kcmil) (mm²) (ω/km) (ω/kft) 0000 (4/0) 0.4600 eleven.684 2.17 zero.856 212 107 0.1608 0.04901 195 / 230 / 260 000 (three/zero) 0.4096 10.404 2.44 0.961 168 85.Zero 0.2028 0.06180 a hundred sixty five / 2 hundred / 225 00 (2/zero) 0.3648 nine.266 2.74 1.08 133 67.Four zero.2557 zero.07793 a hundred forty five / 175 / 195 0 (1/zero) 0.3249 eight.252 3.08 1.21 106 fifty three.5 0.3224 0.09827 one hundred twenty five / a hundred and fifty / 170 1 0.2893 7.348 3.Forty six 1.36 83.7 forty two.Four 0.4066 0.1239 110 / a hundred thirty / 150 2 zero.2576 6.544 3.88 1.Fifty three sixty six.4 33.6 zero.5127 0.1563 ninety five / one hundred fifteen / a hundred thirty 3 0.2294 five.827 four.36 1.Seventy two 52.6 26.7 zero.6465 0.1970 eighty five / a hundred / one hundred ten 196/0.Four 4 zero.2043 5.189 4.89 1.Ninety three forty one.7 21.2 zero.8152 zero.2485 70 / eighty five / ninety five five zero.1819 4.621 five.50 2.16 33.1 sixteen.Eight 1.028 0.3133 126/0.Four 6 0.1620 four.One hundred fifteen 6.17 2.43 26.3 13.Three 1.296 zero.3951 55 / 65 / 75 7 zero.1443 3.665 6.93 2.Seventy three 20.8 10.5 1.634 zero.4982 eighty/zero.Four 8 zero.1285 3.264 7.78 3.06 sixteen.Five 8.37 2.061 0.6282 40 / 50 / 55 9 zero.1144 2.906 8.74 three.44 thirteen.1 6.63 2.599 zero.7921 eighty four/zero.Three 10 0.1019 2.588 9.81 3.86 10.4 five.26 3.277 0.9989 30 / 35 / 40 11 zero.0907 2.305 eleven.Zero four.34 eight.23 4.17 4.132 1.260 fifty six/zero.Three 12 0.0808 2.053 12.4 four.87 6.Fifty three three.31 5.211 1.588 25 / 25 / 30 (20) thirteen 0.0720 1.828 13.9 five.Forty seven five.18 2.Sixty two 6.571 2.003 50/zero.25 14 zero.0641 1.628 15.6 6.14 four.11 2.08 eight.286 2.525 20 / 20 / 25 (15) 15 0.0571 1.450 17.Five 6.Ninety 3.26 1.Sixty five 10.Forty five three.184 30/0.25 16 zero.0508 1.291 19.7 7.75 2.58 1.31 13.17 4.016 — / — / 18 (10) 17 zero.0453 1.One hundred fifty 22.1 8.70 2.05 1.04 16.61 five.064 32/0.2 18 0.0403 1.024 24.Eight nine.77 1.62 zero.823 20.Ninety five 6.385 — / — / 14 (7) 24/zero.2 19 zero.0359 zero.912 27.9 eleven.0 1.29 zero.653 26.Forty two 8.051 /american_wire_gauge three of 6 eleven/11/2008 eight:45 am 20 zero.0320 0.812 31.3 12.3 1.02 0.518 33.31 10.15 16/zero.2 21 zero.0285 zero.723 35.1 thirteen.8 0.810 zero.410 forty two.00 12.Eighty 22 0.0253 0.644 39.5 15.5 0.642 zero.326 fifty two.96 sixteen.14 7/0.25 23 0.0226 0.573 44.Three 17.Four zero.509 0.258 sixty six.Seventy nine 20.36 24 0.0201 0.511 49.7 19.6 zero.404 0.205 eighty four.22 25.Sixty seven 1/zero.5, 7/zero.2, 30/zero.1 25 0.0179 zero.455 55.9 22.0 zero.320 0.162 106.2 32.37 26 zero.0159 0.405 62.7 24.7 0.254 zero.129 133.Nine 40.Eighty one 7/0.15 27 0.0142 zero.361 70.Four 27.7 zero.202 0.102 168.9 fifty one.47 28 zero.0126 0.321 79.1 31.1 0.A hundred and sixty zero.0810 212.Nine 64.Ninety 29 zero.0113 zero.286 88.8 35.0 zero.127 zero.0642 268.5 81.84 30 zero.0100 zero.255 ninety nine.7 39.3 0.One zero one 0.0509 338.6 103.2 1/0.25, 7/zero.1 31 zero.00893 0.227 112 forty four.1 zero.0797 zero.0404 426.9 a hundred thirty.1 32 zero.00795 0.202 126 49.Five zero.0632 0.0320 538.Three 164.1 1/zero.2, 7/zero.08 33 0.00708 0.One hundred eighty 141 fifty five.6 zero.0501 0.0254 678.8 206.9 34 0.00630 0.160 159 sixty two.Four zero.0398 zero.0201 856.Zero 260.9 35 0.00561 0.143 178 70.1 0.0315 zero.0160 1079 329.Zero 36 0.00500 0.127 200 78.7 zero.0250 zero.0127 1361 414.Eight 37 0.00445 0.113 225 88.4 zero.0198 0.0100 1716 523.1 38 0.00397 0.One zero one 252 99.Three zero.0157 zero.00797 2164 659.6 39 0.00353 zero.0897 283 111 0.0125 0.00632 2729 831.Eight forty 0.00314 zero.0799 318 125 0.00989 0.00501 3441 1049 the "approximate stranded metric equivalents" column lists normally available cables inside the format "quantity of strands / diameter of man or woman strand (mm)" that is the not unusual nomenclature describing cable creation inside an average cross-sectional location. Some common cables are halfway among awg sizes. Cables offered in europe are usually categorized according to the combined move segment of all strands in mm², which can be compared directly with the place column. Within the north american electric industry, conductors larger than four/zero awg are typically recognized via the vicinity in heaps of round mils (kcmil), where 1 kcmil = 0.5067 mm². A circular mil is the vicinity of a cord one mil in diameter. One million circular mils is the location of a cylinder with one thousand mil = 1 inch diameter. An older abbreviation for a thousand circular mils is mcm. Outdoor north the united states, cord sizes for electrical functions are usually given because the pass sectional area in rectangular millimeters. Worldwide preferred manufacturing sizes for conductors in electric cables are defined in iec 60228. Be aware that the area in mm² may additionally differ extremely from the numbers given inside the table, depending on number of strands and so on. Pronunciation /american_wire_gauge 4 of 6 11/11/2008 8:45 am awg is colloquially called gauge and the zeros in big cord sizes are called aught (pronounced /t/). Cord sized 1 awg is referred to as "one gauge"; in addition, smaller diameters are stated "x gauge", in which x is the advantageous integer awg wide variety. Large wire (#zero and up) is known as "one aught", " aught" and so forth, depending on what number of zeros are inside the awg score. [8] references donald g. Fink and h.
