    There is no one formula to calculate total connected load and size a service.

    Easier to do it than explain all the variables.

    Need total square footage of each level and purpose, what is the occupancy type, name all major electric appliances amp or watts and voltage, type of lighting. Type of heat and electrical size, size of air conditioning, and other misc loads not listed.

    And all as accurate as possible.


    This will keep you busy for a while.

    You can read the process in Article 220 of the
    NFPA 70: National Electrical CodeŽ

    Don't read it alone, it can make you run screaming into the night.
