A great tool for electrical engineers and electricians.
This app will calculate:
The voltage/percent drop for a wire
Minimum wire size for a given percent drop
Max wire length for a given percent drop
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).
Email the answers to others.
Uses the 2008/2011/2014 National Electric Code (NEC) values for impedance
