This is my receptacle tester that I use every day. So if you’re not a professional journeyman electrician this is how Professional Home Inspectors test receptacles. To try to explain, two green lights means the receptacle is good. If there is only one green light in the middle it means the receptacle is showing open ground which is a safety issue. If it shows one green and one red it means that the receptacle has reverse polarity which means the hot and neutral are reversed and is a safety issue. So today I saw all of the lights lighted. Not sure what this means but it can’t be good. Any professional journeyman electricians out there can help me understand what is happening here? I just know it’s not good so I can explain to my clients. Thanks in advance.
