An essential wiring safety check!

The media could not be loaded. I love the elegant simplicity of this socket tester - plug it in and you get a light pattern that you can match up to the table on the front of the product and diagnose the health of your circuit. It also has a nice GFCI tester to see if it pops when it is supposed to.I think this device is a potential lifesaver. When I made my video (attached) I noticed that I was getting some blinking on the lights that indicated a possible intermittent ground. I popped open the box and found that the groundwire was a little loose despite a green light on the GFCI itself. In a few seconds, I was able to identify and fix a problem I didn't even know I had!

This is a must have for any homeowner. Whether it's trouble shooting an outlet or checking a circuit is off, this socket tester is great. The lights are very bright. The chart is really handy for figuring out what might be wrong.
