Wire Size Calculator
Sizes the minimum conductor (AWG/kcmil) for a given load, accounting for allowable ampacity per NEC Table 310.16, the 3% / 5% voltage drop recommendations of NEC 210.19 and 215.2, and ampacity adjustment for ambient temperature and conductor count per NEC 310.15.
This calculator is in development. The Voltage Drop Calculator is live now; the DC Voltage Drop and Wire Ampacity calculators are in progress.
