I have been checking my outlets in the house, using a voltage probe. Many outlets have voltage (220) on the Neutral pole of a 3 way plug, while others have voltage on the Hot pole of the plug.

I am not using a DVM, or checking potential between hot-neutral and ground.

Is this a problem?

Thanks!

They should (of course) be right and it's the work of a few minutes to correct.

 

In reality, there are very few modern appliances which care, many have reversible 2-pin plugs anyway.

 

There is certainly little immediate danger, but do set about fixing them.

 

EDIT What would be a hazard is L and N swapped at the entrance to the house, so before doing anything else verify that the output side of your breakers is actually the hot.
