ELECTRICAL FORMULATOR PRO combines over 250 formulas, 150 charts and parts of the MN electrical code which is based on the 2008 National Electric Code. Formulas are for both American and Metric systems so both AWG and Mil formulas are given.

The charts include charts on motors, power demand, wiring, and voltage drop and safety codes. The basic program calculates Amps both from AC and DC currents. It calculates kilowatts, horsepower, efficiency, power factor, watts, amps, current, power, resistance, and voltage. It includes formulas to calculate total resistance, capacitance, voltage drops, and transformer calculations. There are also over 300 conversion formulas as part of the program.

Every result in Electrical Pro can be saved. You can also select from favorites and recent formulas, print AND E-mail results

What's New

THE UPDATE REMOVES the 2005 State Code and replaces it with a download links to individual states codes as well as the 2011 National Electrical Code. If you want the code inside your app do not download it. It also adds charts and has minor bug fixes.
