About Electrical Pro Android App

A great tool for electrical engineers and electricians.

This app is a compilation of five sub apps that use the 2008/2011/2014 National Electric Code (NEC).

Locked Rotor Amps
NEC Motor Table Look-up

Voltage Drop Pro:
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 based on the inputted values
Click the green "Voltage" label for custom voltages

Wire Ampacity Pro:
This app will calculate:
The minimum wire or max amps based on the inputted ampacity for low and medium voltages,
The equipment and service ground size
A residential feeder size
Click the green "Ampacity" label to switch between minimum wire and wire ampacity

Note: This app uses the internet for the Google Licensing Service

This app uses the 2008/2011 NEC to calculate values.

Now you can save initial values to be used in the calculations!

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).

This app gives you the ability to email the answers calculated to yourself and others.

See the about menu for additional functionality.
