WireCalc - NEC Wire Sizing

Size wire, check voltage drop, and review your electrical calculations with WireCalc for iPhone and iPad. Guided steps and clearly labeled inputs help you move from circuit details to results you can inspect, copy, save, and share. WIRE SIZING Enter your load, voltage, run length, and installation conditions to find a conductor recommendation. See whether adjusted ampacity or voltage drop determines the size, then expand the calculation to review the sizes checked. Includes the next conductor size and a grounding-conductor sizing hint. VOLTAGE DROP Calculate voltage loss in volts and percent for DC, single-phase, and three-phase circuits. Compare the result with your selected limit, including parallel conductor sets. AMPACITY Check a conductor's capacity or find a size for a target current. Review table ampacity, ambient-temperature and conductor-count adjustments, and the terminal…
