Leviton LB120-DS 20A 1-Pole Plug-On Smart AFCI/GFCI Branch Circuit Breaker, Hydraulic Magnetic, 120 VAC, White

The Leviton Load Centers are great, but some of the double pole smart breakers, the -GS or -ES models, do NOT work with 120/208v systems. Only the standard -S varieties work. Disappointing!

BLUF: I think these are worth looking at if you are already going to replace your breaker panel, if youre looking for energy monitoring only, look into something else like the Sense Energy Monitor (which also has pros/cons). You dont have to have smart breakers, but I like seeing the energy usage for each breaker. The Leviton smart breakers (I have only a handful right now because they are pricey) allow you to receive near-real-time notifications (SMS Text and Email) about the status of your breakers (IE if a breaker is tripped or turned off, you will get notified). You can also monitor the current draw on each of them independently (See picture) as well as receive notifications of high or low voltage. Pros: 1) Smart - Remote Monitoring, bill estimate (with user input) 2) Notifications - trip notifications, status updates (IE: turned on/off), high/low voltage, Self-test failure, and other various 3) Design - If youre tired of the old gray box, this offers a sleek white casing that has a windowed front cover (additional cost) 4) Data hubs can be wired or wireless internet access 5) No wiring to the breaker itself, each connection is made through the lugs on the back of each breaker as you plug it in (up to 6awg 60 amps). Cons: 1) They are expensive. $58 for base (non GFCI/AFCI) single pole SMART breakers and $90 for base (non GFCI/AFCI) double pole SMART breakers. AFCI/GFCI smart breakers are more expensive topping out at $122 for a single pole smart AFCI/GFCI and $162 for a double pole smart GFCI breaker. (NON-SMART breakers are more reasonably priced at $11 single pole and $17 - $22 for double pole. 2) They require the Leviton Load Center breaker panels 3) They do not come in half breakers, each space requires a full space (other panels offer half size breakers to double capacity). 4) To get smart monitoring you need to get 1 x data hub per breaker panel (So if you have a main panel and a sub panel, you will need to get 2 data hubs), they are $149/ea. Bottom line: If you want smart monitoring you have options. Obviously this is the more expensive option as replacing a breaker panel could run more than $3000 for a panel, cover, full set of smart breakers, and installation costs. I opted for this option because my old panel was full and I needed more space. I could have used a sub panel in the utility room but I already have one in the garage and didnt want to have multiple sub panels. If you want independent breaker monitoring and/or control, I have not seen a better option.

Quality materials. If you use the App to monitor energy usage, set alerts on smart breakers for when a fridge circuit doesnt run as an example, or trip breakers - prepare yourself for a very poor experience. It appears they had an issue in December of 2022 that resulted in the usage data just not being there/lost. Opened up a support, after two months I got a response that they would fix it with a future app update. Three app updates later they did, by removing all of 2022 data and only showing 2023 calendar year. But it only works on 15% of my breakers, the others show 0 data. If you are looking for a good quality non-smart breaker, this is a very expensive paper weight basically. If you want some smartness to it with support backing their product - this is not what you should buy, go elsewhere.

I am a licensed electrician. This is my first time using a Leviton panel. I am through my impressed and will use nothing in the future for new construction. Some of their other products need improvement but their redesigned panel and breakers and by far best in class. Also, from a consumer standpoint, the all white look with clear panel cover looks inviting instead of intimidating.

Just what i expected

This serie of Smart breaker makes a buzzing sound when connected to power which is all the time. While one doesnt make much noise by itself, you can hear 30 of them through the door. Thats a real problem for a product so expensive and its simply unacceptable. Ive contacted their support and apparently this is by design. Screw this. Im not building another panel with these... Im committed now but I wont do the same mistake twice.

What more can you ask for? Theyre smart breakers. I used them to monitor my home power consumption and can remotely trip them.

This was one of the worst purchased Ive ever had with Amazon. They listed this as a used, returned item and Ive purchased the smart breakers prior with no issues, however, this one was not smart. Amazon REALLY needs more quality control when items are being returned. They have people checking these items when they have no idea what they are looking at. This breaker is $58 new, I paid roughly $42 for it, when I received it, the breaker was not a smart breaker. It was the cheapest thermal breaker Leviton makes. So, someone purchased this smart breaker and returned a non-smart breaker that cost them $9. I absolutely love the smart breakers, if they are actually smart breakers. Do yourself a favor and spend the extra $18 for a new breaker, At least then youll know its going to be a smart breaker.

Connected to my smart panel with ease. Works well. Live reads working.

What can you say about breakers? All they need to do is work. Tested these and they work properly. Im happy with my purchase and the price was good as well. Easy to recommend the seller.
