App Description
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
