I have a circuit in my old house (built 1918), it’s gone through many remodels during its lifespan and multiple owners.
This one circuit has no grounded outlets, so I had a look behind the outlet to see what the story was. It appears that all these outlets have copper wires back there, so I picked up some grounded outlets and hooked up the copper wires to the ground not - all to no avail. Now my outlets show “open ground”.
I can’t see any other outlets on this circuit, and it appears everything is fine. The only thing relatively near these outlets are two lights (not a traditional light). They are on the wall, and use a twist/click mechanism to turn on and off. Would these also need to be grounded in order for the whole circuit to be correct?
