Re: panel changes / arc fault
In my area, generally, the replacement of the service center, or the upgrade from fuses to circuit breakers, does not, in itself, result in adding AFCIs or GFCIs.
The logic is that no new branch circuit or outlets are being installed.
However, if the number of outlets in an older dwelling doesn't meet a minimum specified in local ordinance, the outlets must be added, and, since they are new outlets, they require AFCI protection on them (only the new ones in the bedroom).
On a side note. . .wasn't it Vermont that requires the use of AFCIs on a panel change out? I seem to recall that most, if not all, 120 Volt 15 & 20 Amp circuits throughout the dwelling were placed under AFCI protection?
