Electrical – Can Ground Attached to Neutral Fool a Receptacle Tester?

electricalgroundinggrounding-and-bondingneutralreceptacle

I'm using a basic outlet tester like the one from picture below. Let's say someone wired the ground to the neutral in some outlet, to provide a fake ground. What would the tester report? Would it be "CORRECT" or would it be something else?

In case it reports "CORRECT" (wrongly, of course), is there some easy way to test that the ground is fake? By easy I mean not having to open the outlet…

Best Answer

The tester will show "correct". Opening the outlet is the only way to check it that I know of.
