AC 80-260V 100A LCD Digital Display Multi-Function Power Monitor Voltage Current Frequency Power Factor Energy Meter Ammeter Voltmeter with Split Core Current Transformer

I originally bought two of these to monitor a generator circuit that I'm installing for my house.But first, I wanted to see how much power my house was using so that I could make sure to not overload my generator.After installing two of them on the main lugs, I decided that I would keep them, because it's nice to see how much electricity your house is using at all times.The wiring is easy. If you're looking at the back of the box, the current transformer (CT) goes into the top two terminals (doesn't matter which color goes in the top or bottom). Then, your 'hot' wire goes into the third terminal and the neutral wire goes in the bottom terminal.I was able to wire these while my panel was hot. I have the 'hot' wires coming out of my 30A dryer breaker, so I was able to cut it off while wiring.I'm using 10GA wiring and it fits inside the screw terminals.ONE THING TO NOTE! Do not attach the current transformers to the live wires without already having it screwed into the meter. Google risks of an open CT and you'll see why.Overall, I'm super satisfied with the meters. The light is bright and the numbers are easy to read. They seem accurate, but I don't have any way to prove that.Also, since I had four of these at my panel, I bought a sheet of ABS plastic to mount them into and they look nice!

I recently installed a backup generator for power outages. I installed this meter in the transfer switch panel to monitor both Line & Gen power. It works perfectly, and for the price, it can't be beat. Thus far, it has accurately monitored the average Wattage in real-time, current Amperage, Hz, and most importantly, a cumulative kWh reading until its reset. It also monitors how efficient your utility company is providing power to you (Power Factor). Interestingly, while performing generator tests, I discovered my generator is actually more efficient than my Utility company! I'm very satisfied with this product.

The first teacher that I like the most is that I do not have to cut the wire to install these. Thanks for the way it opens up and snaps back into place. Good size display with the information. I need to verify the frequency of the power that the generator is putting out and also the load that I have on my generator to make sure it is not being overloaded when powering home appliances during a power outage here in Texas

operation of unit is excellant. instructions to hook up power was poor. since i knew center of light bulb is hot and side is ground or common it was easy for me hook up. instructions in booklet could be much better and larger for us old people to see

Used two of these to monitor power from generator. Really easy to install because the sensor clamps around the cable.

I ordered 2 of these units because I needed to track my whole-house electric usage and if you have split-phase (220 Volt AC) service as most do in the United States, you need to install the CT's on each leg of the service leads in your fuse box or circuit breaker panel.After several months of use, the combines kWh readings are spot-on with what the utility meter outside indicates. But it is much more convenient to be able to see at a glance how many Watts you are using at any given moment. Even with just the 2 CT's, you can see exactly how much Watts a given device is using, by making a note of the reading, then turning the device on or off and recording the change.So if you do not want to spend a lot of time and money with a purpose-built whole house monitor, then install a pair of these. One thing to be sure to do is splice the hot wires which connect after a circuit breaker to an in-line low current fuse for safety. This way if the thin wire to the unit develops a short, the low current fuse will open. If you fail to install this way, then the small wire and unit could possible burn unless the main fuse or CB in the panel opens.

does what it says in the desc.

This multifunction power monitor is a great tool for tracking energy usage. The LCD display is bright and easy to read, showing voltage, current, frequency, power factor, and energy consumption clearly. Installation was straightforward with the split-core CT—no need to disconnect wires. It handles a wide voltage range (80-260V) and up to 100A, perfect for monitoring appliances or DIY solar setups. Very useful for identifying energy drains in the home!
