kWh Electric Meter - 120 Volt, 2-Wire, External 14mm 50A Current Transformer

I purchased 2 of these of measure in/out KWh usage in some circuitry and they works very well. I have to use the electrical square box 4 1/4 and custom cut the hole on the plastic cover for the reading. The size is a bit odd and they don't fit any of the standard electrical box. The external CT is well made and the black/read wire is much longer than I need because I put it in the same box as the reading meter.The digits are a bit small and it is hard to read number 1 or 7 but I expected that as it does cost me under $60. I love the non-re-settable feature and the build quality is very high given the price point. So far, I have one readings that reads over 90Kwh and I am happy with it. I also use Android app ECAS to track the readings and they works flawlessly.I was looking for a more IP base setup but they may not have it other than their own cloud push technology that I think are not clean enough. I will look again to see if they have new things to hookup to this little gems.The seller is local and I got it next day! I am very impress with the seller and I keep visiting their store for more cools things like this.

Easy to hook up and is quite accurate, but the downer is that there is no reset to zero KWHs after using. I would not purchase this product again.

We use this to track the electricity usage on a sub-panel for a rental unit, and this unit works great for that. The instructions are clear and detailed, and wiring is fairly simple. The fact that it is non-resetable removes any ambiguity over usage. Also fantastic that it will measure 120 on either one or multiple circuits (uses an inductance monitor).Four stars instead of five only because of the form factor. This thing will not fit into a normal electric box. Plus, the exposed conductive screw-type contacts mean it definitely does need a box. And the only box that fits it well is the company's custom box - which happens to cost as much as the meter, and more importantly is rather bulky/unattractive. These guys could have easily built a unit that was sized to fit a standard electrical box, and just sold a custom faceplate - instead they opted for a custom design and super-spendy custom enclosure. Also, it mounts to DIN rail, which is standard in industry but hard to find in stores like Home Depot.Overall, this is a great meter, and the wiring is easy. It's also MUCH cheaper that the other meters out their, and works on 120 (!!). But make sure you have a plan - and all the specific parts - for your install, because you won't be able to run to your local and find a box to fit it, or a rail to mount it on.

I installed it and I looked st it a month later and one of the zeros turned to a one and that's all it's done. Checked the installation and it was done correctly. It just dont work.

Seems to work fine, but I didn't realize it measures in hundredths of a kWh at first. There is no decimal point. I thought it was junk until I measured it against a Kill-A-Watt meter. They measured exactly they same once I realized that. There are plenty of digits in the readout so it should be fine. I know it's rated for indoor use only but I set it up to read outside on one of my rental cabins in Fairbanks Alaska. We will see how it holds up at -40*F. It's under the eve in a box and we almost never get driving rain, so I thought I would give it a shot. I wanted something I could read without going into my tenant's space. This was about all I could find. I'm running two legs of the same phase through it to power the tiny cabin. Seems to be working fine so far...

It was easy to install and seems to provide an accurate reading of electric usage by the tenants.

It's kind a ok... it was small though

Great item... so far working great
