Reply to comment by speedyspaghetti in Ungrounded 3-Prong Receptacles Question by speedyspaghetti

It will tell you if it's grounded to the panel or I very least to a ground rod. Which is where you want to be grounded anyways..

So as long as the outlets show grounded on my plug-in tester after doing what I suggested above, I'm good?

I'll probably just pull off the cover on all the outlets in those two rooms to ensure that nothing else janky was done.

To really be certain, it would be a good idea to get a multimeter and verify that you are getting the correct voltage when testing between hot and ground (should be the same as testing between hot and neutral). You can do this carefully with the bare wire in the box before cutting it. But be careful, as you would be reaching into the back of the potentially live box with a probe while the circuit is energized!! (Highly recommend safety gloves if you do this.)

Technically it might also show grounded if it's touching a metal box that also is metal all the way back to the panel, or if it's tied into a neutral prior to getting back to the panel.

I would personally stick with the plan of making the first outlet in the circuit a GFCI. You can still tie into the wire that may be ground, and if it's wrong, the GFCI will still attempt to protect you.
