Comment 2-119 210.12(B)
Panel Action: Accept in Principle in Part Vote: Vote was unanimous because this was referred to the action on Comment 2-95
The panel took a more measured approach to the AFCI expansion through the action on Comment 2-95. See the commentary on Comment 2-95 (below) for more information.
The NEMA reps recommend voting in favor of the panel action with an affirmative comment on vote (only to note that the panel statement should reference 2-95 instead of 2-85).
Comment 2-95 revised the text of 210.12(B) to read as follows:
(B) Dwelling Units. All 120-volt, single phase, 15- and 20-ampere branch circuits supplying outlets installed in dwelling unit family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sun rooms, recreation rooms, closets, hallways, or similar rooms or areas shall be protected by a listed arc-fault circuit interrupter, combination type installed to provide protection of the branch circuit.
The vote on this comment was 7-3-1. IBEW, IAEI and IEC voted negative because they believe the expansion should have been to all circuits.

Are you guys assuming these exempts kitchens, bathrooms, garages, and outside branch circuits?
