Perform accurate Voltage Drop and Wire Sizing calculations for both NEC® (National Electrical Code) and IEC standards. Built for electricians, engineers, and contractors who need reliable results on the go. Voltage Drop Calculator • Dual standards: Switch between NEC (AWG/Imperial) and IEC (mm²/Metric) • Enter voltage, current, run length, and power factor • Supports continuous load (125%), grouping, and ambient temperature corrections • Copper or Aluminum conductors for single-phase and three-phase systems • Detailed results including ampacity, derating, voltage drop, and load voltage • Automatic compliance checks (e.g., ≤ 3% for branch circuits) Wire Size Calculator (Reverse) • Calculates required wire size for a target voltage drop % • Suggests optimal AWG, kcmil, or mm² • Uses NEC Chapter 9, Table 9 (AC impedance) with DC fallback Professional Tools • Wire converter (AWG/kcmil ↔ mm²) • Generate and share PDF reports • Handy electrical formula cards • Localized in English, Spanish, French, German, Italian, Dutch, Portuguese, and Chinese
