I am currently remodeling my house and most of the wiring is 2 wire w/ no ground. I'm not remodeling my upstairs but do have access to the first out let of 3 outlets up there that are on the same breaker. If I replace the wire up to that first outlet and leave the the wiring to the others because i can't replace it will the outlets further down the line be "grounded"? If not any suggestions?
