ECN Forum Forums General Topics of the Trade General Discussion Area Receptical Tester

I appreciate the explanations. As I've mentioned once or twice before, I worked with an electrician who was super safe and super competent, but tended to answer my questions with, "Because I said so."

He was also a strong proponent of the Wiggy.

You can't fool a Wiggy with induced voltage, but be careful, they can play the devil with electronics. A lot of our wiring was done in the 1960's...no EGC and 480 and 120 in the same pipe.

While it's pricy the TASCO does a slick job.

The nice thing about them is that they test for conditions in the blink of an eye that otherwise take a lot of time and expertise.

TASCO is the actual manufacturer of many of Greenlee's circuit testers, BTW.

How does a night light show reverse polarity? please explain.

You are right. Maybe we should call them "reverse polarity testers". That is really the only difference between them and a night light ... unless there is a bootleg ground off that reverse polarity connected receptacle, then it says "OK".

McClary's: Welcome to ECN. The poster was referring to, in a disrespectful manner, the plug-in receptacle testers ... you know, the ones with three little lights.
