In 210.52(B)(1), it states, "Receptacle Outlets Served. In the kitchen, pantry, breakfast room, dining room, or similar area of a dwelling unit, the two or more 20-ampere small-appliance branch circuits required by 210.11(C)(1) shall serve all wall and floor receptacle outlets covered by 210.52(A), all countertop outlets covered by 210.52(C), and receptacle outlets for refrigeration equipment."
I would interpret this to mean that the dining room receptacles are to be on the two or more 20-ampere small-appliance branch circuits required by 210.11(C)(1). :smile:
