Description:A fast, accurate voltage drop calculator designed for electricians, engineers, contractors, and DIY users. Instantly estimate voltage loss, choose the right wire size, and validate compliance for residential, commercial, and industrial projects. Supports single and three phase, copper or aluminum, and both AWG and metric sizes.
Core features
- One-tap voltage drop and percent drop with final voltage and power loss
- Smart wire sizing to meet target voltage drop based on load, length, and material
- Flexible inputs: AC/DC, single/three phase, AWG or mm², copper/aluminum, imperial or metric units
Why it’s better
- Fast and reliable results for job site decisions and engineering checks
- Code-aware defaults and practical presets for common circuits
- Clear, shareable summaries for quotes, submittals, and documentation
Keywords: voltage drop calculator, electrical calculator, wire size, AWG, NEC, IEC, electrician tool, engineering productivity
How to use:1. Download and open the app, then set units, phase type, and your target voltage drop in Settings.
2. Enter source voltage, load current or power, circuit length, and choose copper or aluminum.
3. Tap Calculate to view voltage drop, percent drop, final voltage, and suggested wire sizes in AWG and mm².
4. Adjust inputs to compare scenarios, switch single or three phase, and refine length or load to meet your target drop.
5. Save or share results as a report, duplicate past jobs as templates, and use offline at the job site for quick checks.
