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. The AWG table below is for a single, solid, round conductor.
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.
2nd NEC 210.16 table includes aluminum wire (or copper-clad aluminum wire) ampacities from 18 AWG to 2000 kcmil for all 3 temperatures. Here is the 1st chart, followed by the 2nd chart. Table of Contents
16 gru 2023 · Here is the table that comes with different values, like the resistance of wire gauges and the current value for copper conductors with plastic insulation. The diameter details in the table are for solid wires. Standard wires are measured by measuring the equivalent cross-sectional copper area. AWG#.
18 kwi 2023 · The following chart is a guideline of ampacity or copper wire current carrying capacity following the Handbook of Electronic Tables and Formulas for American Wire Gauge. As you might guess, the rated ampacities are just a rule of thumb.
