Just swapping out a old 100 amp Zinsco main panel question

[zappy]

I'm going to install a new 100 amp main panel. Not adding any new circuits. Would I need to install AFCI breakers for the bedroom circuits? What if it's a multi-wire branch circuit, how would you protect it with a AFCI breaker? Also, when you install AFCI breakers on old wiring, do you usually have problems with them tripping? Thank you for your help.

We are not required to add AFCIs to existing circuits on a panel change out. Adding openings at the time would, of course, change things.

No ACFIc needed for what you are describing in NJ.
If we were to add any new circuits then, yes ACFIc needed on all non GFCI protected circuits.

Same here, but not the same in all California jurisdictions.

Just found out in Manteca they don't require them, when you just swap out the main.

Not needed at all in NJ for existing dwellings unless it's a new construction, addition or add a level

But don't forget that second ground rod!
