I just got a house that was built in ‚Äô61. Some of the outlets are 2 prong, and a couple are 3 prong.
The 2 prong outlets do not have a ground wire in the metal box (all of the outlet boxes are metal), and the couple that are grounded have only a ground wire from the outlet to a screw in the box.
Is this an adequate and safe way of grounding? My polarity/ground tester tells me that they are OK.
If this is in fact OK, I will do the rest the same way.
Note: The main panel is grounded to earth via a post in the cement in the garage.
Thanks for any help‚Ä¶‚Ä¶‚Ä¶
