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

This works great. I too was worried about the size of the 1x area being too small for my amp meter to fit into it. I have two amp meters and they both work fine. This is an inexpensive tool and for the average person will work fine. It feels and looks great. Most typical amp meters will fit both the 1x and the 10 x . It allows you to read amps, check ground fault ,location for volt readings and any polarity issues. I took a chance with it. Knew that I could always return it for a refund. It has worked fine for me and went ahead and ordered a second one for a another electrician that doesnt have one. Glad I got this.

Well, it’s super tough to get a heirloom quality tool these days, so don’t expect that. But this essential tool works well enough. 4 stars for accuracy. Both the 1X and 10X slots should read the same (decimal point should just be moved over 1 place), but they are 3/10ths of an amp off from each other at 12 amps. That’s not too bad, but it’s not what it should be.

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

A good addition to any tool box.

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.

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.

This is one of those where have you been all my life tools. Combined with a good clamp meter its an indispensable tool for an electrical DIYer or pro.

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

I use this for checking electrical outlets daily. After 2 days of using this tester, the ground prong became loose which pretty much rendered this tester useless.

I use this for work and it is very important to be accurate. I have used at least seven or eight different types. This is the one.
