Your cart is empty. This AC Line Splitter provides a fast and easy way to “Split” standard 120V/240V AC electrical lines, eliminating the need to cut off the plug and separate the conductors.
When you test a device, use this splitter to separates the hot/live conductor from the neutral and ground, which enables users to measure AC current – up to 15 amps on a two-wire or three-wire lines — using a clamp meter.
This splitter provides two openings — one opening provides one-to-one current measurements, and the other provides times-ten (X10) readings so that low-current readings will display with higher resolution on a clamp meter.
This splitter also provides two Voltage Test Jacks so that voltage can be measured with another multimeter while you are reading the current on the same line.

Very satisfied. Makes it very easy to tell what a 110-120V circuit is pulling.

Well made device to enable measuring of current with a clip on amp meter. I highly recommend this product.

I'm an IT administrator and this along with a decent clamp meter is great for effectively calculating circuit load for power conditioners and UPS's. The internal 10x loop is great for measuring for devices that draw only small bits of current like switches, POE Injectors, and certain AV equipment.I get the same reading from this device on the 1x loop as I do right from the receptacle wiring; the 10x loop though seems to read slightly higher than 10x. I'm not sure if it's a discrepancy in my clamp meter (I have a $75 Southwire clamp meter) or if it's this device. I have an AC fan in my office for instance that measures 0.36 A on the receptacle, 0.37 A on the 1x loop, and 3.98 A on the 10x loop.The housing is rugged and held together with four screws. The plug fits snugly into an AC outlet. The receptacle on this device seems secure as well. I've not been using it very long, but (just as an example) I'm able to plug a 12v 2A DC power brick into this and then into the wall without any support at all, and everything stays plugged in.I know plenty of electricians have made their own split-wire current tester, and it's not difficult. The devices I test are always under 15 amps, so this feels like a more compact and polished way to take a measurement without taking your receptacle or breaker box apart.

To measure the current draw of a load with a cord that is plugged into a standard 120 volt AC outlet, you can use a line splitter, which allows you to use a clamp on ammeter to get a reading. I selected the Tekpower M920 AC line splitter because it looked sturdy, had two openings for measuring, and was reasonably priced.The opening closer to the plug end provides the actual current rating (1X). For better accuracy, the second opening provides 10 times the amperage (10X). Depending on the sensitivity of your meter, you may be able to get a more accurate reading. As an example, you might read 0.4 amps on the 1X opening, and 0.43 amps on the 10X.Build quality is excellent, and the orange color makes it more noticeable and hopefully less likely to be misplaced. The openings are large enough to be easily accessed by most clamp-on ammeters. If you want to measure how much current a 120 volt plug in device, or an outlet strip is drawing, this tool will make that possible.

Seems durable and works as advertised. Like the 10X feature. Voltage sampling plug design could be improved.

Its OK; I just wish it had a higher amp rating as some applications can draw far more than 15 amps. other than that it did not stay straight when plugged into the socket. What I mean by that is after you plug it in, it will sag/ tilt downward slightly. Not normally a problem; but I would not want it to tilt down so much as to where it falls out of the socket. It probably wont happen, but is a concern.Overall a good product.

I bought this for detecting a ground leak that was causing a gfci circuit to trip. I modified it to break out the ground lead so I could monitor that individually. This splitter works great w/o any mods but be aware of the following:- the voltage check holes are just holes to poke a meter at the hot and neutral lines. The pseudo button below these holes is ... nothing.- the 1x 10x lettering only applies when looking from the top of the unit (with the voltage check holes). On the backside the lettering is backwards and the 1x 10x slots are on the neutral line. A pretty stupid mistake that they didn't bother to fix. That is the reason for only 3 stars

Comes in really handy when you have to evaluate equipment with a compact power cord. I only need it once in a while, but it makes that particular job a snap without opening up connections or destructive cable cutting. I love it!

................. this is not a very complicated product so this review will be very simple I originally purchased this particular item for testing electrical loads on indoor and outdoor Christmas decorations. I compared this product to numerous other similar products listed on amazon and I purchased this unit based on price and reviews as well as I liked the red color over colors of similar products listed. this product is so simple that the difference between one line splitter to another should be almost NILL. I use this splitter In conference with an EXTECH brand 200 amp clamp meter and find it to be very easy to use. plug the line splitter into a short grounded extension cord than plug the device or item to be tested into the splitter and attach your ammeter to the side of the unit on the x1 or x10 hole which multiplies the load times 1 or 10 connect to power and your ammeter shows amperage load down to the tenth of an amp based on your ammeters display. multiply that number by 120 volts and now you know your total wattage load for instance 10 amps multiplied by 120 volts =1200 watts obviously. understand that the exact calculation depends on the real voltage coming into your home or business so you may want to add a good quality voltmeter to this purchase to know the exact voltage to use in all calculations because small changes in voltage can heavily affect the final calculation especially at higher loads over 10 amps or more remember this unit Is rated at a total of 15 amps or approx. 1800 watts. understand if your ammeter has a built in voltmeter an independent volt meter may not be needed. again all final calculations depend on exact voltage so in final summation this is simple and effective and not in need of a super informative review and in combo with a good quality ammeter and or voltmeter this device will get the job done in an easy and low tech fashion.

Superstorm Sandy was a near miss for us but the experience convinced me that all NJ residents should probably have a generator. I bought this line splitter to use with my Amprobe ADC-10 Plus to help me select the correct type and size. It allows the Amprobe to measure both running AND STARTING currents on plug-in appliances, something I can't do with my WANF wattmeter. The line splitter provides correct readings on both the X1 and X10 coils. It also survived my accidental "drop test" so I'm guessing it's well constructed. At the price, the Tekpower M920 AC Line Splitter is a good buy.
