App Description
The field electrician's voltage-drop calculator — NEC and IEC in one honest tool.
Enter system voltage, load current and one-way run length, pick the conductor, and read the drop in volts, the percentage and a clear verdict against the 3% / 5% recommendation. Switch between NEC (AWG/kcmil, K-factor method, feet) and IEC 60364 (mm², resistivity method, meters) — copper and aluminum, single-phase and three-phase, adjustable power factor.
PRO
• Both standards in one app
• Reverse sizing: enter a target % and get the smallest conductor that passes, with ampacity and breaker suggestion
• Save calculations to history
• Share clean PDF reports
Built for gloves and sunlight: big keypad, huge results, Outdoor Bright mode.
Everything stays on your phone — fully offline, no account, no tracking.
Results are planning estimates; always verify with your local code authority.
