    By doing a demand load calculation.

    This doesn't mean you are going to add up all the circuit breakers, or all the loads--seeing that not all loads will be utilized simultaneously. So, there is a number of factors (demand factors) that has to be considered. Where do we start: The NEC-Article 220.

    First: General lighting load
    Second: AC over Heat or versus heat
    Third: App's (Appliances)
    Fourth: Dryer
    Fifth: Cooking appliance or equipment
    Sixth: Service or feeder size
