Thanks folks. I'm a card carrying Republican. (not sure of the connection)
I make my own cards.
Is a service change - 60A to 200A - a modification to branch ckts?
Without consulting code, IMHO I'd say it is not a change of the circuits themselves, but is a change of breakers such that circuits which would require AFCI, and for which AFCI is available, would need to now be AFCI. Someone might argue that if all the old breakers can be used in the new panel, they can be used and grandfathered in (I wouldn't fight that argument, but would not pose it, either).
