Wire gauge calculator. * @ 68°F or 20°C. ** Diameter and cross sectional area do not include the insulation. *** Results may change with real wires: different resistivity of material and number of strands in wire. Voltage drop calculator .
Learn how circuit wires must be sized to match the ampacity of the load placed on them by using an electrical wire size chart.
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.
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.
April 18, 2023. AWG Wire Sizes (see chart below) AWG: In the American Wire Gauge (AWG) system, wire size diameters can be calculated by applying the formula D (AWG)=.005·92 ( (36-AWG)/39) inch. For the 00, 000, 0000 etc. gauges you use -1, -2, -3, which makes more sense mathematically than "double nought."
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.
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.
