Electrc NEC Calcs Pro is an Android Phone and Tablet version of our popular desktop application, Electrc NEC Calculator.

This app will perform your most common electrical calculations based on the current National Electric Codes. Metric units is included.

Transformers.

Box Sizing for pull, junction, and splice boxes.

Conductor Sizing based upon load amps, voltage, NEC Table for installation types, ambient temperature, terminal temperature, rooftop installation, voltage drop percentage, quantity of additional current carrying conductors, load duty, number of parallel conductors per phase, single or parallel raceways, and circuit type. It includes many built in conductor types.

Conduit and Trough Fill for any number and type of conductor and raceway combinations.

Fault Current calculations based on the point to point method, for calculating available fault current at the end of a run of conductors, or at the secondary of a transformer, or at a distance downstream of a transformer secondary.

Voltage Drop calculations based on conductor type, material and size, and circuit type, as well as the quantity of conductors per phase.

Underground cover (Burial depth).

We are continually adding new features to the app, so please let us know if you would like to see any other features added.
