I have a contractor stating that in a dwelling unit where the heating equipment is placed in a closet he is not required to install AFCI protection for the 20A duplex receptacle circuit in this closet even though the closet is large enough for storage. He is calling it a “Utility Closet” and therefore exempt. I do not see “Utility Closet” defined in the code nor do I see any such exemption. Article 210.12 lists closets but does not exempt “Utility Closets” in dwelling units. What say you?
Thanks, Mike Supranovicz, EE
