Triplett AC Line Splitter and GFCI Outlet/Receptacle Tester with 5 Visual Indicators (ET200)

Works flawlessly and does not feel cheap. No regrets. Sometimes the lights are not clearly distinguishable under bright conditions but you just use your palm to give it some shadow and thats it.

A good addition to any tool box.

Works effectively, great for DIY electrical repair. The GFI test switch is the main reason why I bought this, and it works. Very simple product, easy to use.

This appears to be substantially the same as several similar units I have or have used. The new thing (to me) is the GFCI testing button. If its not apparent from the picture, the thing that looks like a guard around the GFCI testing button isnt. Im not really sure why its there at all; the button protrudes a few millimeters and takes very little force to depress. So far, Ive successfully tripped a known working in-wall GFCI... and proved to my satisfaction that a GFCI-protected extension cord I bought for cheap from Wal-Mart is probably unsafe / defective(?). (If the GFCI light comes on, probably even for a moment, while connected to a GFCI-protected circuit, its probably time to get a better GFCI. In the case of the extension cord, the GFCI light stayed a bright, solid, ominous red for as long as I cared to hold the button down.) I dont have any out-of-code outlets or appliances Im aware of, so theres a slight question mark about the other functions; it does light the completely correct pattern for all of my known-good outlets, extension cords, etc.

Great line isolator for taking readings. Works great.

Good product with multiple functions.

Handy item to measure what current a device actually draws. Use TRUE RMS clamp-on !!

just plug in and clamp on your clamp meter. 10X helps for small currents

This little gadget is a life saver for determining polarity

I live in an area that electric power goes out during thunderstorms. I bought and use a portable generator to keep the essential house items running but always had concerns of overloading the generator. I bought this product and have used it several times with no difficulty and I am now can be assured that the generator is well within its capability for keeping me comfortable in my home.
