The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F).

Wire Size Ampacity & Breaker Size Charts Based on AWG. Derived from the wire gauge chart and based on AWG sizes, the following fig shows the commonly used wire gauge size for different applications. Click image to enlarge

AWG Wire size chart and ampacity table for design engineers including skin depth frequencies and tensile strength data; electrical cable size

In this AWG wire gauge chart for a standard copper wire, you can find every AWG wire; from the biggest 10+ mm wires (such as 4/0 AWG and 3/0 AWG wires) to the smallest below 0.01 mm wires like 39 and 40 AWG wires.

A wire gauge chart is an invaluable tool for determining the ampacity and gauge of wires. These charts include details such as resistance, allowable current (ampacity), and diameter for solid wires. They provide essential information like the diameter and resistance of different wire sizes, making it easier to select the right wire for specific ...
