Adoption is solely bestowed on your state and local governments, a good site is NEMA, they give me updated about NEC fifteen states away! :smile:

As far as requirements.......ALL 120v 15 and 20 amp branch circuits supplying outlets installed in dwelling unit family, living, dining, parlor, libraries, den, bedroom, sunroom, rec room, closet, hall, or similar rooms or areas shall have AFCI prot.

Unless you run the branch circuit "home run" in rmc, imc, emt or ac cable.:D

The real question is: Where are you inspecting, and who has jurisdiction for that specific building and who is the authority having jurisdiction (AHJ).

Some places are still on the 1996, 1999, 2002, and many are still on the 2005.

Then, are there "local" (State, County, City, etc.) amendments that the have changed 210.12(B) which, as you call it, is the AFCI requirement.

Your best information is going to come from the local jurisdiction.
 
Don't forget that even if you are using the 2005 code, you must use the combination type AFCI devices.
 
Also in addition to all the info provided . Knowing what edition of the IBC or IRC your state is observing will tell you which NEC is being referenced. Also indeed the provision of being combination rated is in effect all the way back to he 2005 NEC and 2006 IRC.

An arc fault is still required on this circuit with ac cable, etc.

Arc-Fault Circuit-Interrupter Protection.
(A) Definition: Arc-Fault Circuit Interrupter (AFCI). A device intended to provide protection from the effects of arc faults by recognizing characteristics unique to arcing and by functioning to de-energize the circuit when an arc fault is detected.

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, sunrooms, 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.
FPN No. 1: For information on types of arc-fault circuit interrupters, see UL 1699-1999, Standard for Arc-Fault Circuit Interrupters.
FPN No. 2: See 11.6.3(5) of NFPA 72?-2007, National Fire Alarm Code?, for information related to secondary power supply requirements for smoke alarms installed in dwelling units.
FPN No. 3: See 760.41(B) and 760.121(B) for power-supply requirements for fire alarm systems.
Exception No. 1: Where RMC, IMC, EMT or steel armored cable, Type AC, meeting the requirements of 250.118 using metal outlet and junction boxes is installed for the portion of the branch circuit between the branch-circuit overcurrent device and the first outlet, it shall be permitted to install a combination AFCI at the first outlet to provide protection for the remaining portion of the branch circuit.
Exception No. 2: Where a branch circuit to a fire alarm system installed in accordance with 760.41(B) and 760.121(B) is installed in RMC, IMC, EMT, or steel armored cable, Type AC, meeting the requirements of 250.118, with metal outlet and junction boxes, AFCI protection shall be permitted to be omitted.
