We're new homeowners, and are replacing our electrical switches & outlets, mostly for cosmetic reasons.
I noticed that the outlets I purchased have a green-screw that is intended for a ground-wire, however, none of the existing outlets being replaced are connected to such wires. I just don't a 'ground' wire present in our existing wiring. There's typically just two wires (the black & white).
Obviously I'm new to doing my own electrical. Is this wiring configuration typical for an 11-year old home? If so, how would the outlets be grounded?
