page 70-161, "Allowable ampacities of insulated conductors rated 0 through 2000 volts, 60°C through 90°C, not more than three current-carrying conductors in raceway, cable, or earth (directly buried) based on ambient temperature of 30°C. The standard ASTM B258-02 (2008), Standard Specification for Standard Nominal Diameters and Cross-Sectional Areas of AWG Sizes of Solid Round Wires Used as Electrical Conductors, defines the ratio between successive sizes to be the 39th root of 92, or approximately 1. For more information about the relationship between cross-sectional area and AWG, please refer to our wire gauge calculator. Knowing it can handle 17 amps we can calculate that the 16 gauge wire has the capacity to handle 2,040 watts (at 120V) and 3,740 watts (at 220V).

Formula for calculating the cross-section (Area; An) of an AWG wire (n denotes the AWG gauge number). If you’re looking for wire size for a 10 amp circuit (this can be for a 10 amp 120-volt circuit, breaker, battery output), you will need an AWG with at least 10 amp rated ampacity at 75°C.Larry Campbell is an electrical contractor with 36 years of experience in residential and light commercial electrical wiring. To answer these questions, we would require these kinds of equations (don’t be alarmed; these just illustrate what kind of complex formulas we are to simplify): Formula for calculating the diameter of an AWG wire (n denotes the AWG gauge number).

As indicated in the Formulas and Rules of Thumb sections above, differences in AWG translate directly into ratios of diameter or area.Multiply the resistivity (Ω•m) of the conductor material by the peak motor current (A), the number 1. For instance in your 20 amps circuit, “ If you want to have an even safer circuit, you can use 12 AWG wire as the 20 amps wire size.

Current (ampacity) Notes: The current ratings shown in the table are for power transmission and have been determined using the rule of 1 amp per 700 circular mils, which is a very conservative rating. volts (2%) is best for large cables like battery cables 4AWG (25 ISO) or larger, carrying large currents. Use the calculator below to figure out the cross-sectional area of the cable, then use the Cable Size Chart to match it to the nearest size. Keep this in mind when evaluating wire size and type for your application, as AWG doesn’t apply to stranded or non-round wires.
With 130 amps capacity, 1 gauge wire can serve as a battery cable, welding cable, or any other power cable that requires a good 100 amps of electric current.
