Wire & Cable Size Calculator (Copper & Aluminum)

Wire & Cable Size Calculator (Copper & Aluminum)

Today, we are here with another comprehensive Copper and aluminum wire size calculator

As we have discussed in detail the topic of “How to calculate the proper wire size forElectrical Wiring. Now you can take the advantage of this calculator to do this job J

• You can also check the classical Wire & Cable Size Calculator in (AWG)

Calculating Wire/Cable Size formula for single Phase Circuits

Wire Circular mils =2 x ρ x I x L / (%Allowable Voltage drop of source voltage)  

Calculating Wire/Cable Size formula for Three Phase Circuits

Wire Circular mils =√3 x 2 x ρ x I x L / (%Allowable Voltage drop of source voltage)  

Where;

ρ = Specific resistance or resistivity of Conductor

D = Distance in Feet (One way) i.e. ½ the total circuit length

I = Load Current

Note: the Value of ρ = Specific resistance or resistivity of Conductor is used here for copper and aluminum is 11.2 and 17.4 respectively at 53° C (127° F)
