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

lover that theres also voltage probing points

This is one of the durable standards for this type of tester.

I assume it is accurate on the 1 times but the 10 times is more like 11 or 12 times. Which seems odd. I am pretty sure all they needed to do was loop (or coil) the wire 10 times so that the meter would read 10x the electrons flowing by.

A line splitter allows you to use a clamp ammeter to measure the current an appliance uses. Some people have been saying the 1X hole in this one is too small so here are the measurements 28 x 19 mm The 10x hole is 26x26 mm. Now you can measure your own clamp meter to see if it will fit. To use a clamp meter to measure current you cant clamp it around a cord, you have to clamp it around just ONE of the wires and its hard to do that on most appliances without cutting the cord apart. This line splitter lets you measure anything that plugs into a wall socket. Just plug the splitter in, plug the appliance into the other end and clamp your meter through one of the holes. The 1x hole shows the actual current, the 10x one amplifies it by ten times so you can measure small currents more accurately. This Triplett line splitter does the job and is well built so it can survive in a toolbox. It also has a couple of added functions I like. A set of three lights will tell you if your plug is correctly wired and grounded, a GFCI button will safely test a ground fault protected outlet and there are two holes you can insert your meters probes into to safely measure the voltage. You can save a few dollars by getting a line splitter without these features but I like having them. This will work for up to 15 amps which is the same as all other line splitters I have seen on Amazon. I know MOST outlets in the United States are fused for 15 amps so that is probably the biggest appliance you will ever need to measure, but I would have liked it if they had increased the current just a bit more, like to 20-25A just in case you wanted to measure something that was overloading your breakers or was on a heavier duty circuit. But this use would probably be rare, so Im ok with the limit. You could do the same thing by separating the wires in a normal extension cord, or by connecting a plug and socket with 3 short heavy wires. But honestly, by the time youve bought the parts and put them together, you would probably have spent more time and money than this line splitter costs. And this tool neatly avoids any safety issues with a DIY solution. Just remember, to use this to measure current you need to already have a clamp ammeter.

Serves the purpose of checking Amperage but can be a little awkward

Good product with multiple functions.

Identified an open Ground on one of my outlets. Remember if you are going to measure AC Current that you will need a Clamp-On Ammeter.

Includes 1x and 10x inductive current monitor loops built in. What I really wanted. 4 time larger than the standard GFCI tester.

Its not a very stylish design, unlike some others, but on the other hand, it works perfectly, first time, every time, unlike many of the competitors. The lights are clear and bright, the button wont get pushed on accident, but is easy to trip when you want, and the GFCI LED is undeniable proof when the outlet isnt working right. Pushing the button instantly trips working GFCI outlets before the LED can light-up, and makes it incredibly quick and easy to go through an entire house and check out every single outlet in record time, easily making it worth the purchase price in just the first 10 minutes of use. Even if youre tired of the proliferation of specialty tools you need to carry around, like I am, this is one to get, as a multimeter takes so damn much longer. Dont bother with other models, just because they look sleeker... They got it right with this one.

Does everything I’d expect. Nice idea both tools in one. Very convenient for this RV tech.
