Hot/ground show reversed at receptacle

Tested a receptacle that gave a hot grd reverse reading. From what I read this is really a loose neutral connection. Have a non contact voltage detector that shows power when inserted in the larger slot of the receptacle. The smaller slot of the receptacle does not show power. Is the polarity of the receptacle reversed? If so why would a reverse grd reading be shown? Also, have two different brands of plugin testers and one shows hot grd reverse and the other shows correct on the receptacle. Thanks.

The plug in testers require either a good ground or a good neutral to give a reading that makes sense, and different models can give different readings when something is wrong, depending on their internal design.

The non-contact testers are not very helpful at diagnosing problems, they are really intended to warn you that power is present nearby.

Suggest you get an inexpensive analog multi-meter to properly diagnose the problem. If I had to guess, I would suggest a missing ground and hot/neutral reversed.

Wires Reversed

Reversed wires could be at the receptacle in question or it could be at the receptacle immediately upstream.

Thank you for the info on the testers and advice. The non voltage tester did indicate reverse polarity, which it was.
