Sperry Instruments GFI6302 GFCI Outlet / Receptacle Tester, Standard 120V AC Outlets, 7 Visual Indication / Wiring Legend, Home & Professional Use, Yellow & Black

I bought this because I already own a different GFCI tester that is frustrating to use. This yellow Sperry one works as a wall tester should - you plug it in, and it CLEARLY shows if all is OK, or else what is wrong. By clearly, I mean there is a light for "CORRECT" that lights up instantly when you plug in. You do not have to turn it on first, it does not require additional batteries of its own, like my other tester does, and the output is clear and non-confusing. This is gold compared to my other tester. Love it, worth every penny.

Nice to have to double check outlets. Works well, as expected.

I do electrical work as a hobby mainly because my home needs all new wiring. Wiring is actually fun too but wanted a tool to be able to test my wiring job. Although it does not test every thing it test what I need. So far every outlet I tested says it is wired correctly.I like how the writing is on both sides because the outlets can be put with the ground up or with the ground down. Some power prefer it with the ground up some people like it with the ground down. It actually does not matter which way you put it as long as it is wired correctly. Any way that was why I choose this one because most of the other ones I was looking at only had it on one side.This also has a handy GFCI tester that I found very handy and works great.Oh on a side note. A mistake on my part and I do not blame Amazon although I am not sure how it happened but some how I ordered 3 of these instead of ordering just 1. I didn't even realize until after I started tracking the order and saw it said 3 of. I looked closer and realized I did in fact order 3 and I paid the price for 3. Not a major deal though. I will just keep them all just in case I loose one. It would not be in case one breaks though because they have a life time warranty which I guess is also a plus. It would also not be the first tool I have more then one of. I have like 3 hammers and that was because I kept loosing them. I even lost my nice ladies one that was nice and light.Speaking of ladies tools I would love to see this come in pink. Although I do not think it would sell as their are not many of us women who like this kind of stuff and like pink as well.

Inexpensive, simple, compact, and easy to use. I like that it has the status light legend printed on both sides and is shown in the reverse orientation on the bottom so if your outlet is mounted upside down you can easily determine what the status lights mean.The one issue I had, and why I marked it down by one star, is that they don’t provide instructions in the packaging. Instead they included a note that says go to their web site to download the instructions which means you have to get online and search their site to find instructions for this model tester. What really annoyed me was that the instructions make no mention of how to use the GFIC test button and if pressing it on a non-GFCI protected circuit is dangerous to me, the tester or the circuit. I had to go online to research this to give myself a warm fuzzy about how that works.So, how to use the GFCI test button…Plug in the tester and push its test button. If the power goes off, the outlet is protected by a GFCI breaker or outlet and is working. Press the reset button on the outlet or breaker to restore power. If the power doesn't go off, replace the GFCI or the outlet you are testing is not protected by a GFCI.How does the test button work and will it harm a non-GFCI circuit?When the test button is pressed a small ground fault (current flow) is created between the hot and ground conductor. If the GFCI is performing properly it notes the differential in current flow between the neutral and hot conductor and break the circuit. The ground fault current is low enough the it won’t harm or trip the circuity breaker on a non-GFCI protected circuit.

Inexpensive, small and essential to have in any home! Most efficient way to troubleshoot electrical outlets and figure out which circuit breakers or reset GFIs to use. Simple to use too!

A rugged well made tool that works very well. Same hi vis yellow plastic and black rubber grips as Dewalt Tools.I really like the adjustability of it. At full sensitivity, I get it within a few feet of a circuit or fluorescent light and it starts buzzing. All the way down and it does not detect anything, so the range of adjustment is fantastic. I can dial it in so precisely that I can hold it on one side of an insulated wire and it will not go off, but when I move it to the other side of the wire (where the hot conductor is) it goes off. That's accuracy to a few millimeters.Best way to use it is to calibrate it ahead of time. Stick it in the hot side of an outlet, on a wire or conduit, hover it over a wall switch or outlet that you know is hot and adjust the knob until it buzzes, now it's ready to test the unknown circuit.I live in a 60+ year old house with plaster and chicken wire lathe wall construction. At a little more than 1/2 sensitivity it detects the wires inside the wall, inside of metal conduit. By moving it back and forth and seeing where the buzzing starts and stops, I can trace exactly where that wire is in the wall between the studs. Makes it easy to trace or detect wiring in the walls before I cut or drill through.If you will only use one of these to stick into outlets or against wires to see if they are hot then the adjustability feature may be overkill, but to get a lot of varied use, I'l glad I chose this one.
