Description
Voltage Drop Calculator (NEC/IEEE)
• Enter voltage, current, length, and power factor
• Supports continuous load (125%), conductor grouping, and ambient temperature correction
• Choose Copper (Cu) or Aluminum (Al) conductors
• Single-phase or three-phase systems
• Detailed results: base & corrected ampacity, voltage drop, percent drop, compliance badges (≤ 3% branch, ≤ 5% feeder + branch)
Wire Size Calculator (Volt Drop)
• Suggests correct AWG/kcmil size based on allowed percent voltage drop
• Flexible length input in meters or feet
• Supports wire sizes in mm², inches, and AWG/kcmil
• Uses NEC Ch.9 Table 9 (AC impedance) or DC fallback for accuracy
• Displays suggested size with area, voltage drop, percent drop, and load voltage
Extra Tools
• mm² ↔ AWG Converter
• Formula cards for quick reference
• Export results as PDF/Report for sharing or records
