I'm moving my main panelboard as part of a service upgrade. The panelboard is brand new (i.e. I'm not reusing the old board).
Do I need to add CAFCI/GFCI breakers on the old branch circuits (as would be required for new construction/new branch circuits)? For example, there's no GFCI on my washing machine branch circuit, but Code requires this circuit be GFCI protected for new construction. Other examples: there's no AFCI anywhere in the house. I could go on.
The house is located in Seattle, USA, was built in 1927, and contains a mix of knob and tube, NM (original), and NM-B wiring as well as a bit of armored cable here and there. Eventually, we'll completely rewire the house, but the previous homeowner just added outlets wherever he saw a "convenient" place to tap into an existing circuit. That's probably good reason for adding CAFCI/GFCI protection, but I'm concerned I'm going to be fighting nuisance trips until I can do a proper re-wiring job.
Answers that cite the relevant Code are appreciated!
