Cable & Wire Gauges

Increasing gauge numbers denote decreasing wire diameters, which is similar to many other non-metric gauging systems such as British Standard Wire Gauge SWG , but unlike IEC , the metric wire-size standard used in most parts of the world. This gauge system originated in the number of drawing operations used to produce a given gauge of wire. Manufacturers of wire formerly had proprietary wire gauge systems; the development of standardized wire gauges rationalized selection of wire for a particular purpose.

The AWG tables are for a single, solid and round conductor. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor. Because there are also small gaps between the strands, a stranded wire will always have a slightly larger overall diameter than a solid wire with the same AWG. AWG is also commonly used to specify body piercing jewelry sizes especially smaller sizes , even when the material is not metallic.

By definition, No. The ratio of these diameters is , and there are 40 gauge sizes from No. Because each successive gauge number increases cross sectional area by a constant multiple, diameters vary geometrically.

Any two successive gauges e. The diameter of a No. Sizes with multiple zeros are successively larger than No. For instance, for No. 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 with plastic insulation. The diameter information in the table applies to solid wires.

Stranded wires are calculated by calculating the equivalent cross sectional copper area. A circular mil is the area of a wire one mil in diameter. An older abbreviation for one thousand circular mils is MCM. AWG gauges are also used to describe stranded wire. The AWG gauge of a stranded wire represents the sum of the cross-sectional areas of the individual strands; the gaps between strands are not counted. Stranded wires are specified with three numbers, the overall AWG size, the number of strands, and the AWG size of a strand.

The number of strands and the AWG of a strand are separated by a slash. As indicated in the Formulas and Rules of Thumb sections above, differences in AWG translate directly into ratios of diameter or area. This property can be employed to easily find the AWG of a stranded bundle by measuring the diameter and count of its strands. This only applies to bundles with circular strands of identical size. To find the AWG of 7-strand wire with equal strands, subtract 8.

Similarly, for strand subtract See the Mathcad worksheet illustration of this straightforward application of the formula. Measuring strand diameter is often easier and more accurate than attempting to measure bundle diameter and packing ratio. Such measurement can be done with a wire gauge go-no-go tool such as a Starrett or Mitutoyo —, or with a caliper or micrometer. Consecutive AWG wire sizes larger than No. From Wikipedia, the free encyclopedia. North American standard for electrical wire diameters.

AWG Diam. The table above only lists the AWG standard. Watch for round-off errors, as many numbers were rounded. Use the table as a guide. The weight [pound per foot] does not include wire insulation. The weight of the wire is critical in some applications.

The AWG tables are for a single, solid and round conductor. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor.

Whether your vehicle is a Ford or a Ferrari, our automotive wire is the optimum choice for 12 volt and 24 volt DC electrical systems. If you need a higher temperature and performance wire, use crosslinked SXL wire instead. Each copper wire core is composed of smaller gauge strands of pure copper creating high conductivity, flexibility, and durability. Ideal for wiring 12 volt or 24 volt electrical systems with a maximum voltage rating of 60 volts. Available in small bundles, and larger spools. Manufactured from 19 strands of 23 gauge copper covered in a durable PVC insulation. Made in the USA.


Table 1 lists the AWG sizes for electrical cables / conductors. In addition to wire size, the table provides values load. (current) carrying capacity, resistance and.

Nandaniya says: September 13, at am. As we have established above, how you identify electrical cable size is through the size of wire it houses e. Current is measured in amperes or "amps".

As strands of wire are made, they are drawn through progressively smaller dies. This is true of all wire. In fact, the AWG sizing system suggests this drawing procedure.

 Мне срочно нужно такси. Охранник покачал головой. - Demasiado temperano.

Для панков? - переспросил бармен, странно посмотрев на Беккера. - Да. Есть ли в Севилье такое место, где тусуются панки. - No lo se, senor. He знаю. Но уж определенно не здесь! - Он улыбнулся.  - Может, все-таки чего-нибудь выпьете.


The following chart is a guideline of “ampacity”, or copper wire current carrying temperature limit, thickness, thermal conductivity, and air convection and.


 Никто не слышал. Это было сделано тайно. - Мидж, - сказал Бринкерхофф, - Джабба просто помешан на безопасности ТРАНСТЕКСТА. Он ни за что не установил бы переключатель, позволяющий действовать в обход… - Стратмор заставил.  - Она не дала ему договорить.

Он разыграл звонок по телефону. И в результате одолел Хейла, освободил Сьюзан и выиграл время для переделки Цифровой крепости. Сьюзан с опаской посмотрела на связанного шифровальщика. Стратмор сидел на диване, небрежно положив берет-ту на колени.

Но вышла ошибка. Я, пожалуй, занесу его в полицейский участок по пути в… - Perdon, - прервал его Ролдан, занервничав.  - Я мог бы предложить вам более привлекательную идею.

 И, разумеется, Христофора Колумба? - просиял лейтенант.  - Он похоронен в нашем соборе. Беккер удивленно посмотрел на. - Разве. Я думал, что он похоронен в Доминиканской Республике.
