Pass-through DIN Rail 120 240 Volts. KWh energy meter

Hooked to 240 volt sub box as instructed, turned power back on, and it is working as advertised. Great little device to measure power use at a secondary breaker box, and required no special wiring. Two hot wires pass through matching opening in device, hook back up to main lugs, screw two small screws into those hot wires, turn on power, and it cumulatively measures kwh. Perfect, at a reasonable cost.

I was doing some research into how much power my mini splits were actually using. I pulled the wires from the breaker, crimp spliced an extension, and VoiLa! Super fast, super easy, and only temporary for a 30 day sampling. I do wish it had a 0 reset option, but other than that, it seems well made, from sturdy materials. I would definitely recommend this meter.

Works as described. The only problem is the screws that tap the wires are a bit flimsy so if the wire is just a little too big to use the bushings, you have to really hold the wires steady to get them to cut into the Insulation as theres enough space the screws just go around the wires. After installing it I wish I had just drilled the bushing out to fit my wire. That would have been a fix.

Great product

I purchased this meter to monitor the watt-hour consumption of my Nissan Leaf electric car. I installed it in series with a volt/amp meter (also purchased from Amazon) so that I have a complete picture of the what goes on during charging. The system works just as planned. I am happy and would buy it again.

Ok

Came as described, easy to install. Not so easy to mount...best to get the DIN Rail...I used a home made bracket. I can now monitor electric use on a 50 Amp circuit that has an RV on it. Perfect.

Powerful little product. I had my misgivings about it at first, but not anymore. We use it to monitor the usage of my son Rv and it works great. Thanks guys.

Bien satisfaits! Je suis capable de savoir combien j'ai consommé à la cabane à sucre durant le temps des sucres!
