--- title: Autocalc description: Calculations are automatic. Changes are instant upstream/downstream. With 7 million integrated equations, PowerCalc ends repetitive and tedious calculations. --- [![Powercalc_Logo.png](https://www.powercalc.co/hs-fs/hubfs/Images/Powercalc_Logo.png?width=592&height=91&name=Powercalc_Logo.png "Powercalc_Logo.png")](https://www.powercalc.co) # autocalc *Just 3 inputs / circuit= over 300 NEC and other code outputs* *[![AutoCalc_Image_3_Arrows_white.jpg](https://www.powercalc.co/hs-fs/hubfs/AutoCalc_Image_3_Arrows_white.jpg?width=178&name=AutoCalc_Image_3_Arrows_white.jpg)](https://powercalcpak-1002713.hs-sites.com/powercalc?hs_preview=QwaVfwRt-4330596770)* **  Inputs **   *PowerCalc* is smart software with a proprietary database. *  [Just 3 inputs / circuit](https://www.powercalc.co/inputs-/-outputs) = over [300 NEC and other code outputs.](https://www.powercalc.co/nec-code) *   1. Electrical Load (kVA) 2. Type of Electrical Load (lighting, motor, etc.) 3. Circuit Breaker # of Poles (single or 3 phase power) That’s the *entire *power distribution system in a building from the branch circuit to the electrical service…for *any size* building, for *multiple *buildings like a campus or a high rise building. [more on inputs / outputs](https://www.powercalc.co/inputs-/-outputs) **Automatic Calculations and Changes** Calculations are *automatic*. Changes are *instant *upstream/downstream.* All* panel boards are generated *simultaneously *(not just one panel board at a time). [more on panels](https://www.powercalc.co/panels) With 7 million + integrated equations, *PowerCalc* ends repetitive and tedious calculations. Input each value just *one time* for repeated use across the entire design. Then, directly export to AutoCad or Revit (*coming soon*). [more on Save Time / Save Money](https://www.powercalc.co/save_time_and_money) *PowerCalc* is a patent protected innovation. Covered by US Patent # 7,636,650. [more on patent](https://www.powercalc.co/patent) **Outputs** With just the 3 inputs listed above, *PowerCalc* *automatically calculates*, and *instantly re-calculates for all changes*, over 300 NEC compliant outputs.* PowerCalc* also makes certain that the power distribution system is not over designed (saving the owner money) or under designed (a safety concern). [more on NEC and other standards.](https://www.powercalc.co/nec-compliance) **Manual Override** Although *PowerCalc* automatically defaults to the appropriate values of the NEC and other standards, the user can also elect to *manually override* these [inputs / outputs](https://www.powercalc.co/inputs-/-outputs) for the job and design requirements. **Wizard **[![wizardwand.jpg](https://www.powercalc.co/hs-fs/hubfs/wizardwand.jpg?width=35&name=wizardwand.jpg "wizardwand.jpg")](https://www.powercalc.co/wizard) To make it even easier, *PowerCalc* has a Wizard. The user can elect to design using the full panel schedule or using the Wizard to pop up a circuit-by-circuit screen for input.
