2017 NEC. A homeowner wants to upgrade their existing electrical system by installing a new external meter-base/disconnect and a new internal panel box (probably 200A ). Many of the original branch circuits are 2 wire circuits without an equipment ground. Do you require AFCI protection for all circuits as required for Art. 210.12(A)?
Does changing the over-current protection (new panel) qualify as modifying the branch circuit [210.12(B)]?
Thanks for your reply.
