I have an old offgrade concrete block house in Jacksonville, FL built probably in the late 50's or 60's. The old gray non-grounded wire. The house has a 2 in 12 pitch roof as well: very shallow. I re-wired part of the house myself under permit from the city: kitchen and bathrooms to be specific (I tested for it, etc). I am now thinking of re-wiring the remainder of the house as the old cable is getting rather brittle.
My question is: If you were to re-wire a house with a shallow 2 in 12 pitch attic area that also had an offgrade area, what cable would you run where? All lighting fixtures and switches through the attic, and receps through the offgrade area?
