## What is Voltage Drop Wire Calc?

Voltage Drop Wire Calc helps electricians, maintenance techs, and contractors get the minimum AWG they need with fewer mistakes.

Use it to:

- choose single-phase, three-phase, or DC 2-wire mode
- enter voltage, current, one-way length, and drop target
- compare copper and aluminum options
- review a full common-size table and see the first size meeting target
- save recurring jobs and rerun them from local history
- keep all data local on device with no account

Why people pay for Voltage Drop Wire Calc:

- faster than doing repeated drop math in the field
- helps reduce oversizing and undersizing mistakes before purchase or install
- gives a narrow on-site answer instead of a bigger electrical software stack
- useful for both branch-circuit checks and feeder planning
