Wire Size Chart. Electrical current is measured in amps. Each wire size, or wire gauge (AWG), has a maximum current limit that a wire can handle before damage occurs. It is important to pick the correct size of wire so that the wire doesn't overheat.

Amp ratings vs. US AWG wire gauges. 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.
31 lip 2024 · Here's how you calculate AWG (American Wire Gauge) from the diameter of a wire: Find the ratio (R) of the wire diameter to either 0.005 inches or 0.127 mm. Use the equation n = -39 × log 92 (R) + 36 to find the AWG number.
The Wire Ampacity Calculator will quickly calculate the maximum allowable current through a conductor based on wire size (AWG or kcmil), wire insulation, conductor type and installation method.
This wire size calculator will calculate the appropriate wire gauge for a circuit based on amps, voltage, distance, and load. This website provides a wire size calculator, voltage drop calculator, wire ampacity charts and more.
Calculate the wire size needed for a circuit given the voltage and current rating required. Plus, calculate the size of a wire gauge in AWG.
How to Calculate the Wire Ampacity Rating. You can calculate the ampacity rating of a wire or conductor by referencing the chart indicating the allowable wire ampacities of insulated conductors that is provided by the National Electric Code.
