Dang that looks complicated. Canada just says 1 outlet = 1 amp for general purpose so a 15 amp circuit can have a max of 12 outlets including general lighting outlets but obviously not switches. Special loads at the connected load and we calculate a house up to about 1000 sq ft is 5000 watts for basic plugs and lights and add another 1000 watts for each added 1000 square feet. Heat, 6000 w for the range, and appliances over 1500 watts are added separately at %25 after the range has been accounted for.
If a house calculates under 100 amps they still have to wire for at least 100 amp service.
the philosophy winds up almost the same service size but we never get more than 12 plugs and or lights on a circuit.
