These are also a must have, IMO. You can confirm outlet wiring and they'll test a GFCI. And I think they are supposed to be a better test than the button on the GFCI, but I don't remember exactly what I read.

Thanks to all who have weighed in. I have called in an expert so we will see what he says. Using my tester on the GFCI outlet it tests green or all ok. Mystery. When expert sparky figures it out I will post the solution
