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.
A wire size calculator assists to select the correct size of electrical wire based on amps, voltage, distance, and load. Proper wire selection is critical for a sustainable electric circuit to resist the voltage drop and current carrying capacity.
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.
The Circuit Distance Calculator calculates the maximum circuit distance based on the maximum percent voltage drop. This calculator also calculates the voltage drop and the resulting voltage at the load.
Example 1: Calculate the wire size for a 20-ampere, 120-volt circuit with a wire length of 50 feet using copper conductors. Using the AWG formula: AWG = (20 x 50) / (12 x 0.005) = 16.67 AWG. Using a wire size calculator tool, we get: 16 AWG for a 20-ampere, 120-volt circuit with a wire length of 50 feet using copper conductors.
Advanced Wire Size Calculator Calculates wire size based on amps, wire insulation, conductor and installation. Also, adds correction factors for voltage drop, temperature and number of conductors.
Calculate the wire size needed for a circuit given the voltage and current rating required. Plus, calculate the size of a wire gauge in AWG.
