A replacement electrical panel is not required to upgrade to combination-type AFCI breakers if: 1) the panel does not include any new circuits, and 2) any extensions of the existing wiring to accommodate the new panel are not more than 6 feet [NEC 210.12(D)(Exception)].
Otherwise, combination AFCI-protection is required for all circuits that have been modified, replaced, or extended, and serving the areas listed in NEC 210.12(A): “kitchens, family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreational rooms, closets, hallways, laundry areas, or similar rooms.” The protection can be provided by AFCI-breakers in panel or an AFCI-receptacle at the first receptacle outlet of each branch circuit [NEC 210.12(D)].
