About this deal

The size of an electrical wire means the cross-sectional area it has (and in turn its diameter). The larger the area, the more current the wire can transmit with lower resistance. It is pretty similar to water flowing in a pipe. Using a larger pipe allows more water to flow at a lower pressure. Values for resistance are based on electrical resistivity for copper 1.724 x 10 -8 Ω m (0.0174 μΩ m) and electrical resistivity for aluminum 2.65 x 10 -8 Ω m (0.0265 μΩ m). t 1 t_1 t 1 ​ — Reference temperature corresponding to the resistivity ϱ 1 \varrho_1 ϱ 1 ​ at that temperature; and Change the temperature, if necessary. The value should be the maximum operating temperature that is expected for the wire.

Input what percentage voltage drop is allowable. The smaller, the better, but the limit is 5% to keep devices working properly.By definition, No. 36 AWG is 0.005 inches in diameter, and No.0000 is 0.46inches in diameter. The ratio of these diameters is 1:92, and there are 40 gauge sizes from No.36 to No.0000, or 39 steps. Because each successive gauge number increases cross sectional area by a constant multiple, diameters vary geometrically. Any two successive gauges (e.g., A and B ) have diameters whose ratio (dia. B ÷ dia. A) is 92 39 {\displaystyle {\sqrt[{39}]{92}}} (approximately 1.12293), while for gauges two steps apart (e.g., A, B, and C), the ratio of the C to A is about 1.12293 2 ≈ 1.26098.

AWG is also commonly used to specify body piercing jewelry sizes (especially smaller sizes), even when the material is not metallic. [2] Formulae [ edit ] A = I ϱ 2 L V = 25 × 1.88 × 1 0 − 8 × ( 2 × 100 ) 0.03 × 120 = 2.61 × 1 0 − 5 m 2 × 1000000 = 26.1 mm 2 = 51.6 kcmil = 3 AWG \begin{align*} Select which electrical system you will be using. Either DC/AC Single-phase or AC Three-phase. That means the calculator can be a simple DC wire size calculator, all the way up to an AC three-phase tool. 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.Multiply the resistivity (Ω•m) of the conductor material by the peak motor current (A), the number 1.25, and the total length of the cable (m).

The higher the number - the thinner the wire. Typical household wiring is AWG number 12 or 14. Telephone wire is typical AWG 22, 24, or 26. Since square meters are not a sensible unit for electrical wires, the result is usually in mm² (if using the metric system). This conversion can be achieved by multiplying the result of the equation above by 1,000,000. The resistivity of a conductor depends on its temperature, so the environment you will be installing your wire in will affect the wire size. When specifying a temperature, try to think of the maximum temperature the wire is likely to operate in, to be on the safe side.The AWG table below is for a single, solid, round conductor. Because of the small gaps between the strands in a stranded wire, a stranded wire with the same current-carrying capacity and electrical resistance as a solid wire, always have a slightly larger overall diameter. Add standard and customized parametric components - like flange beams, lumbers, piping, stairs and more - to your Increasing gauge numbers denote logarithmically decreasing wire diameters, which is similar to many other non-metric gauging systems such as British Standard Wire Gauge (SWG). However, AWG is dissimilar to IEC 60228, the metric wire-size standard used in most parts of the world, based directly on the wire cross-section area (in square millimetres, mm²). The AWG originated in the number of drawing operations used to produce a given gauge of wire. Very fine wire (for example, 30gauge) required more passes through the drawing dies than 0gauge wire did. Manufacturers of wire formerly had proprietary wire gauge systems; the development of standardized wire gauges rationalized selection of wire for a particular purpose. It is common for wire sizes to be given in AWG (American Wire Gauge) units in the US. For more information about the relationship between cross-sectional area and AWG, please refer to our wire gauge calculator. Input a value for the current of the system. This figure should be the peak current so that the cable can be sized for the worst case.

and abbreviations in electrical distribution Toggle Nomenclature and abbreviations in electrical distribution subsection The wire size calculator will help you select the correct gauge of electrical wire for your next electrical project, such as installing a pump in your garden pond, wiring up your tiny house, or getting power to your shed. Select the wire conductor material, either copper or aluminum. You can also use Advanced mode to set a custom material resistivity at a fixed temperature. American Wire Gauge ( AWG), also known as the Brown & Sharpe wire gauge, is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire. Dimensions of the wires are given in ASTM standard B 258. [1] The cross-sectional area of each gauge is an important factor for determining its current-carrying capacity. Let's say that we are using an AC single-phase system operating at 120 V; a 3% allowable voltage drop; a copper conductor; 25 A peak current; a one-way cable run of 100 m (328 ft); and 50 °C max operating temperature.R R R — Resistance of the wire, measured in ohms. We learned how to calculate it at the wire resistance calculator; The AWG - American Wire Gauge - is used as a standard method denoting wire diameter, measuring the diameter of the conductor (the bare wire) with the insulation removed. AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge.
