    Wondering if the spreadsheet can be updated to include a section for EV chargers complying w/ 625.41 with a drop down from 30A to 100A?

      The NEC standard method is just adding up all units, combining everything into a gigantic house. i.e. 1500 sq ft x 15 units, 30 small appliance circuits, 15 washers, 15 dryers, etc.

        That would be incorrect.

    Thank you very much. I have used this several times. It is helpful for single family residential construction. Also it is very useful as a learning tool: By changing various elements and observing how the total load responds, one can get a sense of what loads have the most effect on the overall demand.

    Nice calculator.
    I did similar for industrial application and with automatic wire sizing.
    It would be great if that would be added in the future updates.

    Also, I could help make it an executable file and not excel dependent.
