Voltage Drop

Calculate voltage drop on the fly!

Calculate Voltage Drop 4 Ways

  1. Voltage/percent drop for a wire
  2. Minimum wire size for a given percent drop
  3. Max wire length for a given percent drop
  4. Max amps for a given percent drop

The impedance of the wire is calculated based on the inputted values (i.e. length of the wire)

Where length is inputted you can use your GPS from your phone to get an approximate distance (only as accurate as the GPS in your phone).

Uses the 2008/2011/2014 NEC values for impedance
