Greg,

Here we go with the "SIMILAR" type of room. I think that is very poor wording in the code book.

I believe originally AFCI were made to prevent using extension cords in bedrooms. So why did it need to be on every other circuit in the house?

Now if you pick up a counter top receptacle, can you pick up a dining room receptacle on the same circuit?

Would that dining room receptacle have to be AFCI?
