Question:
Hello, Great info here, Question has come up re:afci protction.
In apartment/condo units often there are hvac units installed in small closets in the apartment or in the attic space. I beleive that according to art.210.12(A) these units should be arc fault protected. Units in garages or basements wouldn't be included. Your thoughts and comments would be appreciated. Stephen C. McCarthy
There is some confusion in my area concerning section 210.12. Some inspectors want AFCI protection including bathrooms, hardwired furnaces, and dishwashers claiming that they are all 120v outlets. Some inspectors don't want these specific items because they are not specifically listed. We are currently AFCI protecting all other 120v receptacles. Please clarify. Nick Pezzolla

Answer:
Hey Stephen and Nick thanks for your questions and the compliment. The key words are "outlet" and "device" as they are defined in Article 100. Outlets are points on the wiring system where current is taken to supply utilization equipment and includes receptacle outlets, lighting outlets and direct (hard) wired equipment.
All 120 volt single phase 15 and 20 ampere branch circuits supplying outlets and devices in the rooms or areas described in 210.12 must have AFCI protection. If an outlet meeting those parameters is located in a closet in a dwelling unit it must have AFCI protection as stated in 210.12(A).
