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.

The biggest 4/0 wire is the thickest and can carry the most amps (230 amps, to be exact). There are many questions that directly relate to AWG wires, such as: How thick is 14 gauge wire? Basically, we are looking for AWG current rating. What is the cross-section of 16 gauge wire?
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.
Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Cerrowire's ampacity chart helps calculate the load requirement for a circuit.
As we will see in the NEC ampacity chart, copper wires can handle more amps than same-size aluminum wires. That’s because copper has a lower resistivity (1.72 × 10 -8 Ohm×m at 68°F) than aluminum (2.65 × 10 -8 Ohm×m at 68°F).
31 Ιουλ 2024 · The wire size calculator will help you select the correct gauge of electrical wire for your next electrical project, such as installing a pump in your garden pond, wiring up your tiny house, or getting power to your shed.
NEC provides tables for adjusting allowable ampacities when the ambient temperature deviates from an expected range for the temp rating of the conductor, as well as for number of conductors in raceways or cable trays, when part of the wire is exposed to sun or wind, etc.
