So, I have a cape cod style house from 1941. I just got it. First thing I did was to run 3 circuts to the kitchen, dishwasher, disposal, and an appliance line. (these didn't exist before) the kitchen was all on the same breaker as the living room. I also ran a new circut to the 2nd floor of the house for outlets up there. Lights are spread across 2 breakers. I had some help from an electrician to do this.
One thing I told him is that I want to protect the house from any faults caused by old bad wiring. The whole house is done in armoured cable (bx i think). Cloth insulation. It seems to be in really good condition, but I worry about what's in the walls that I can't see.
The electricain seemed confused when I asked him to install an arc fault breaker from the main lights and outlets on the old wiring in the house.
There's a 60 amp breaker on the main line that runs all of the old lights and outlets, Would it make sense to replace this breaker with an arc fault breaker, or all of the indivdual breakers under the main?
Edit: I failed to mention that the house has a 200 amp panel by square d, and there are several other larger breakers for the appliances -furnace, dryer, and so on. All copper wires accept the neutral wire from the power company...
