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.
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
Calculate the maximum allowable wire ampacity for an insulated conductor given its gauge, material, temperature rating, ambient temperature, and conductor count.
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.
Simplify complex wire ampacity calculations with Cerrowire’s convenient Online Ampacity Calculator. This intuitive calculator takes the guesswork out of electrical code compliance, ensuring you select the right conductor size for your specific application.
