All residential wiring is based on demand especially the small appliance circuits. There is no limit as to how many Small Appliance circuits, if two is not enough you can add another, the recommended 2(two) circuits is minimun. Also the refirgerator can be put on its own circuit leaving the small appliance circuits by themselves, and dedicate them strictly for 'Small Appliances'.
For load calculations, of the general lighting, laundry and small appliances the first 3000 VA are taken at 100% and the remainder at 35%, all on demand.
