Hello,
I have a questions about the testers that plug in to a receptacle to check for proper polarity. Does any one know how these testers work? Does it check the hot to the equipment grounding conductor and the grounded conductor to the equipment grounding conductor. The reason I ask is because I have had these testers indicate reverse polarity when the polarity is correct. I have had this happen quiet often when there is not an equipment grounding conductor wired to the receptacle. I have verified proper polarity by going to a grounded water pipe or to a receptacle that has a equipment grounding conductor. I realize that the receptacle still has to be grounded properly. So my question is only about how the tester works and if any one else has experienced the same thing with the tester indicating reversed polarity?
