BTW I have come around/woke up and you are right, they do mean dwelling.
But I still say how would this be enforced. I can put a 6-15 in the living room or even on the kitchen counter and it is legal. Without a GFCI I am going to be hard to get along with but it is legal as far as I know.
That is true, I cant see it being enforced. But I think American manufacturers are the ones enforcing it as I have never seen an appliance less that 1600 watts with a NEMA 6-15.
FWIW they do make adapters that can be bought online that allow Schuko to go into a NEMA 6-15.
Why a risk exists running an alarm clock at 240 in the eyes of the NEC I have no idea but 6-15 can be placed anywhere, even a bedroom. GFCI and AFCI protection can pass too.
