I just attended a class where the subject was circuit testers. I was shocked and you may be also to find out that these testers are not always accurate in what they tell you. For example: If the outlet is not grounded or has a false ground and also has another fault like reversed polarity or a open neutral the tester will real as though everything is OK. The rule of thumb with these inexpensive testers is they do all right if there is only on problem but if there are two or more problems they tell you that everything is fine. I found this to be a little troubling and wondered if anyone else has encountered this and what are our opptions when testing outlets.
