Using wire size 3 0 copper or 250mcm aluminum.

240v wire size calculator. In addition experiment with the resistor and ohm s law calculator or explore hundreds of other calculators addressing math finance fitness health and more. Today we are here with another comprehensive copper and aluminum wire size calculator. Run is 300 ft. This wire size calculator will calculate the appropriate wire gauge for a circuit based on amps voltage distance and load.

The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient air temperature of 30 c 86 f. Electrical wire size calculator. Required cable size mm 2 voltage drop volts percentage drop load amps reset. No guarantee as to the accuracy of these values is given.

When sizing conductors calculations limits wire size to voltage drop and nec ampacity. Please check with your electrical inspector or a licensed electrician for the proper wire size. Caution for guidance only. 120 240 volt system 170 amps 3 v d.

Our calculator yields results that are within code in most locations however we advise you to check your local electrical code. This website provides a wire size calculator voltage drop calculator wire ampacity charts and more. Is this the correct wire sizing for this project. This free voltage drop calculator estimates the voltage drop of an electrical circuit based on the wire size distance and anticipated load current.

And they should be checked with an electrician. This should be used as a reference only. Southwire s voltage drop calculator is designed for applications using awg and kcmil sizes only. Find your nearest branch email our sales team call head office.

A sample of 120 volts single phase copper wire 144 feet one half of a 288 foot circuit with 10 amps load on it yields a number 10 awg wire size. Determines wire size to meet specific voltage drop limits or calculates voltage drop for a specific conductor run.
