I was changing a few outlets in an older home the other day, 2 prong to 3. Bx wiring, all looked in excellent shape. So the 3rd one I changed when I tested it it said open ground. I pulled it out, looked at the bx clamp, etc, tested it right to the armor and no ground. In checking other outlets in that room and an adjacent room, (or trying to) the tester wouldn't go in on two outlets. They were 3 prong outlets and the ground prong was filled in with something. The room was redone she said a few years back due to a water leak. Being bx everything should be grounded which I informed her of. Question is if you did have an ungrounded system were you allowed to install a grounded outlet and disable the ground like that? I ask because an inspector told me you can disable one side of a duplex (break out the tabs) if a single receptacle is required.
