    Default TWO prong outlet indicating 'correct' / not indicating an 'open ground'??

    Here is a photo of a TWO prong outlet indicating 'correct' / not indicating an 'open ground'. (Using a 2-3 prong adapter.) How can this be possible? p.s. I'm pretty sure the tab on the adapter was not touching the plate cover screw.

    Buy a new and better tester.

    I'm thinking this may have been on a GFCI breaker (in the panel). That would give this result, no?

    Also, aside from the amount of voltage, what more information would a wiggy/voltage tester have been able to provide me over the receptacle tester? I'm believe that I need to get one, I'm just trying to understand what more it will give me and in what situations I should use it.

    Thanks

    No, because there is still no "ground path" for the tester to read, other than the adapter's metal tab touching a grounded metal screw in the cover.
