This Calculator will determine the minimum size conductor needed based on a 3% Voltage Drop. It does not take into consideration other factors such as minimum ampacity based on the National Electric Code Table 310-16. ( Allowable ampacitys of conductors ). Consult The Electrical Code for further details.

Please enter your values:

120 Volts Copper Single Phase
208 Volts Aluminum Three Phase
240 Volts
277 Volts
480 Volts
Distance in feet, one-way
Total amperage of circuit
This is your minimum wire size.
