A circular mil is the area of a wire one mil in diameter. See Wikipedia’s guide to writing better articles for suggestions. The diameter of a No. For instance, for No. Please help improve this section by adding citations to reliable sources.
The ratio of these diameters is 1: X” wire, where x is the positive integer AWG number. The table below shows various data including both the resistance of the various wire gauges and the allowable current ampacity based on a copper conductor ametican plastic insulation. The AWG tables are for a single, solid, round conductor.
Retrieved from ” https: Wayne Wite Donald G. Mini Christmas lights were mostly 24 throughwhen that gauge was arbitrarily de-rated from 3 to 2. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor.
Sample Wire Gauge Chart
American wire gauge chart pdf download AWG wire sizes larger than No. For other uses, see AWG disambiguation. In this case, it describes a wire which is equal in cross-sectional area to the total of all the cross-sectional areas of the individual strands; the gaps between strands are not counted.
The ground wire is typically the same gauge as the others, despite not being intended to carry large amounts of current for more than a ;df seconds in downlosd event of a short circuit. Stranded wires are calculated by calculating the equivalent cross sectional copper area. Manufacturers of wire formerly had proprietary wire gauge systems; the development of standardized wire gauges rationalized selection of wire for a particular purpose.

May Learn how and when to remove this template message. Archived from the original on 22 July AWG is also commonly american wire gauge chart pdf download to specify body piercing jewelry sizes especially smaller sizeseven when the material is not metallic.
Circular of the Bureau of Standards No. Table lamp wire is typically 18, while extension cords are 16, with 14 common on cords grounded for outdoor use, and 12 available.

They were forced to use the formerly heavy-duty standard dwnload 22 wire itself de-rated from 5 to 4 ampsplus thicker insulation, which in turn caused them to shortchange customers by drastically shortening the light socket spacing and usable length of sets. The most common type of distribution cable, NM-B, is generally implied:.
Mark Lund, PowerStream Inc. Pages containing links to subscription-only content CS1: Two conductor cable is available with black and red american wire gauge chart pdf download only for this purpose; the outer sheath is likewise red. Any two successive gauges e.
Because each successive gauge number increases cross sectional area by a constant multiple, diameters vary geometrically. Sizes with multiple zeros are successively larger than Yauge. Increasing gauge numbers denote decreasing wire diameters, which is similar to many american wire gauge chart pdf download non-metric gauging systems such as British Standard Wire Gauge SWGbut unlike IECthe metric wire-size standard used in most parts of the world.
Wire gauges Customary units of measurement in the United States. In particular, the maximum permissible overcurrent protection devices may set a lower limit. The number of strands and the AWG of a strand are separated by a slash. This section does not cite any sources.
This section’s tone or style may not reflect the encyclopedic tone used on Wikipedia. AWG gauges are also used to describe stranded wire.
This change also made light strings stiff and unsightly. Retrieved 22 Doownload United States Department of Commerce. High-purity oxygen-free copper can achieve up to
