ok, zones #1 and #4 have some verticals between several wall switches and lights. The supply cable for Zone #4 for the kitchenette comes directly down a stud (way too far from the service box to run at the knee-high receptacle level) and splits into the various receptacles, and in fact runs all throughout the studs. When you think of it, installation of kitchen cabinets for the kitchenette (on floor below countertop, above for plates, etc.) will involve use of a lot of screws placed in the studs. If a GFCI breaker in the service box is used for this zone, and the system is hot when the cabinets are installed, we will know if anything gets hit with a screw or nail.
Thus, I will plan on using AFCI breakers in the service box for zones 1 and 4, and maybe for the open-area receptacles (zone #2) -- since the receptacle cables run horizontally and may be at risk when the sheetrockers do their work.
thx HayZee.
