I put this on another site as well,Thought I'ld try it here too.
Just a twist:

210.12.(B)- Arc fault-For dwelling units, straight forward.

210.18-Guest suites and guest rooms.
If they have permenant cooking (kitchen) they fall under "dwelling unit".210.12.(B). Understood.

Now, forward to 210.60-guest suites,dorms etc.assuming no "kitchen"provisions.
It only states to be in accordance with 210.52.
But 210.52 or 210.60, makes no referance back to 210.12(B).


So, My question is: In a guest suite,dorm rm etc.(210.60) With no "kitchen",
Do these ckts require AFCI?

I see a loop hole. Or is it tunnel vision?
