Are All Wire Lever Nut Connectors Created Equal?

All My Favorite Tools - www.amazon.com/shop/everydayh...
Lever Nuts are my go-to wire connector for all my DIY electrical projects around the house. I have been using WAGO 221 lever nuts exclusively but there are some tempting options on Amazon that look the same for half the price. Today I decided to put a couple of these options to the test to see if there is anything unique about WAGO 221 or if any lever nut will do.

An important point is that Wago connectors are UL listed, most knock offs are not. I'm glad that you showed the spring design, I use Wago connectors for uneven wire sizes such as connecting a #12 wire with a light gauge wire from a celing fixture. The springs need to be independent.

[@Milanesa2010]

Knock off 1 is UL listed

[@beecee5990]

​@@Milanesa2010 knockoff #1 has a UL marking, but depending on the source, it may not be worth the ink used to put it there. There's lots of fraudulent items out there.

I'm sure Wago also stands by their products.

[@LuLu_World]

how do solid vs stranded wire work? any pull tests on conductors?

[@ghostridergale]

I use to think UL LISTED actuality meant something was good quality and safe to use. But then after having many different UL listed items actually get very hot and eventually did catch fire. I learned the hard way that UL listed doesn’t mean much at all for quality or your safety. Especially with items like portable heaters as well as some plug ins that have those little holes to quickly stick wires in to make connections that are really very dangerous since there’s very little contact on wires where it’s being connected and that causes even more heat and do eventually fall! I have had them burn out and fail leaving black marks inside the box where it was really border line of catching fire. If you ever been thru a house fire where you lost everything and it wasn’t your fault that caused the fire especially! The devastation and lost is horrible to have to live through. You don’t realize how the loss of some items that can never be replaced can hurt for many years and the only thing you’ll have is your memories of those items that will tend to haunt you that you don’t have them anymore!

[@markk3652]

I had never heard of wago connections until I hired on with a contractor thru my union hall. They were the only connection device approved for this project. After using wire nuts for so many years in my career, I was dubious about this new system. It took a while to become acclimated to them, but they are much easier to use. The twist bundle that wirenuts connect can have a pullout or missed connection. The wago holds each wire independently in each bay, making a very sound connection. We were mandated to wrap electrical tape around the wago after terminations were complete to prevent the levers from releasing upon installing into boxes or devices.

[@stringlarson1247]

Interesting about the having to wrap the Wago to prevent release. I've been using them in my own home, rewiring where I need to temporarily hook up some circuits to keep things running (always fun to live in the project). I was a little concerned about that issue, especially when I first started working with them using 12awg solid and bending/packing, then unbending/reconfiguring and repacking. It takes quite a bit of pressure to release those, but if all the wires are close to parallel and there is not a tight bend - say a JBox where conductors enter/exit in different directions, this is a non-issue if carefully installed/de-installed/reinstalled. Then there are the 'next-guy' issue to consider. I'm interested in the heat dissipation when wrapped vs. not. I've got an IR camera and will test that before buttoning everything up. It's kinda like people using wire nuts and not pre-twisting the conductors and letting the wire nut do the twisting, which, unfortunately, I've run into often.

Great job and thank you. Electrician over 30 years, now Retired by still love the trade.

[@tamazerd]

One strength of the Wago 221 compared to simpler push in variants is that you can mix solid and stranded wires, it would be interesting to see how the knockoffs perform in such a test scenario.

[@tookitogo]

Yeah, mixing solid and stranded is a massive advantage of them!

[@joshcarter-com]

So many in-wall dimmers and smart-home switches have stranded wire. Being able to safely attach those to house wiring with 100% consistency is the single biggest advantage of the Wago 221 for me.

[@testman9541]

you can mix both in the simple push variand by adding a sleeve on the stranded wires 👍 Quite handy for compact setups...

My concern with the Wago clones of dubious origin is that even if one batch looks good, it's pretty much a crapshoot as to whether your next batch will be equally good. Or bad as the case may be. One thing you tend to get with a known, UL listed brand is that you can expect the quality to be pretty consistent.

[@stringlarson1247]

Indeed. Quality control is a huge issue that is often overlooked/non-extant with cheap-o brand. To me, the whole thing is a non-issue as price is not an issue as I'm not using enough of them to make a difference in cost/profit.

[@philipstaite4775]

Thank you for performing this test, well done. I have watched another test where Wago, wire-nut, and outlets were tested to failure - it requires a significant overload current to get them to melt. IIRC something more than 2x - 3x what you were using here. But that test was conducted on a flat surface, in open air. For me the choice seems pretty clear. As a homeowner/DIYer I might use 10 of these in a year. The quality and history of success of Wago is worth the price. So is the peace of mind. If I were in the business and installing 10 of these before lunch, then I might consider the knock-off #1.

[@AlanDavison]

I use the 222 model for electrical safety testing (think world leader in safety testing 😉). We reuse them hundreds of times and regularly put up to 40 amps through them. They are some of the most reliable connections that I have ever seen. They are completely safe for home use when installed properly.

[@greggv8]

Would be nice if the Connexbox Wagoboxes could get UL listing. They've passed such tough European testing they're approved for inaccessible installation such as inside a wall without and access cover. The trick is the special slots the WAGO connectors slide into to ensure the levers cannot come open. The boxes hold the 5 wire lever nuts or a 2 and a 3 can be put into a slot. But as a person at Connexbox told me, UL wants a telephone number size amount of money for testing.

There are some actually great knock off brands out there though. We use the term knock off as a blanket way of saying less than or not as good as the original but for some brands this couldn't be farther from the truth. No different than having off brand medicine which are equally comparable to the main line brands that charge exorbitant prices that consumers can't afford. Sometimes, the only thing different between the quality of a knock off and a name brand is how much R&D was spent developing a product but once the blue print is out there it's easy to copy for knock offs at a lower cost making it more accessible for everyone.

But I wasn't terribly impressed with their push-in connectors.

[@rwefree9469]

I wasn’t aware of Wago connectors before seeing your videos. I bought a nice assortment for a reasonable price and used a couple on a recent home project. They made the install incredibly fast, simple and secure, not to mention the space saving. Bye bye wire nuts. The cost vs. wire nuts is not an issue as I only work on my own home so don’t have a use for large quantities. However, even if I did, the time savings might be enough to offset the cost difference. Thanks for opening my eyes to this product.

[@PartTimeRonin]

If I'm sure I won't need to change anything soon I usually put heat shrink or electrical tape over the Wago to make sure the lever won't get snag and open itself up but I can still cut it open and reuse the connector quite easily. The knock-off is quite useful for end-of-the-line connection to low-current stuff like LED light etc., other than that I definitely use the Wago.

[@HeikosGarage]

WAGO has been a staple for electrical installation in Germany sunce the 70s. When the US was using wire nuts, germany used a push in connector made by WAGO. In my electrical installation kit i have some WAGO push in connectors from the 80s. The lever nut is a new design but the concept if a easy to use connector is very old. It is amazing that it has taken so long for it to make it yo the US.

Great video! I'd like to see one of the torture tests on the knockoffs, see how much current they can handle and for how long before they fail, how the fail, and if they cause a fire and if so under what conditions. This would confirm (again) how good the Wagos are, how good knockoff 1 might be, and just how bad knockoff 2 really is. It would also be nice to include the new Ideal brand lever connectors and the new Leviton lever receptacles and switches just to be thorough.

I'm not surprised. This is also true with XT connectors, Anderson Powerpole connectors, SAE J1772, etc. The knockoffs are not rated to the same spec as the original manufacturer. Even NEMA 14-50R cheap knockoffs overheat and I've seen them and almost cause a fire. Not worth the risk if in your house unattended. Great video. I haven't seen these knock offs yet, but since I use Wago, I would have wondered.

They're OJ-26x, where x is the number of connector positions.

Would love for you to test the wattage reduction when doing these comparisons. The heat testing is a bit of a proxy for showing you that energy is being lost in the form of heat, but it does not tell us the specifics. Especially important to know if you are planning on wiring a series, like outlets, with them as the power loss could become meaningful by the end, especially for products like like knockoff #2.

You should do a test on the Wago after clamping like you normally do, and then repeat with a proper "tug" on the wires after clamping to seat them. The Wago bites in a bit as you check the connection by giving it a tug to make sure it has taken hold. It changes the resistance quite dramatically in my tests.

I've since found the Ideal brand lever nuts from Home Depot and have been very happy with those. I think the levers on the Ideals have a tiny little bump on the sides to help lock it down in place, which helps immensely in preventing accidental lifting of the levers as one is maneuvering in tight electrical boxes and the positive locking also provides a little extra strength helping to prevent wire pull outs.

The Amazon link for knockoff #2 alleges that they have the same 105C (221F) as the Wago; however I consider that the Wago has about 100 degree buffer before failure where the knockoff is getting much, much closer to failure (assuming that the company that makes #2 is telling the truth). Knockoff #2 is also not UL certified. I would much rather spend the $0.60 per Wago and get quality (and not have my house burn down) over cheaping out with the the $0.20 per knockoff connector and result in loss of life.

Hi, Great video, I work in the industry, though Wago is one of the competition. From professional to consumer design in electronics connectors and switches seems to be last on peoples minds. Always the least budgeted item and believe that because its such a simple device/end result (ie joining connections together) they can skip on costs. Sadly most of the time the failures are on these connection points, its not on the silicons/passive components etc. Its really on connection, be it poor assembly or poor quality of manufacturing. Few additional points to note on off brands - the QC is most likely to be more relaxed, in both assembly of the part and the tolerance of the materials, moulding or forming of the metals. As a manufacture of consumer goods, typically yields of 90% is "acceptable". Can you imagine the destruction it can cause if 1/10 of your connectors fail? In reality the consumers acceptable range would be 1/10,000 to 1/100,000, which is getting closer to automotive level of manufacturing. Now realise you are paying $0.x for something nearly automotive grade product, that extra $0.0x difference is what you are paying for.

[@amsoiltek]

Hello Scott, great video. I see lots of RV mfg now using those connectors and I wonder how they hold up to a moving earthquake? Maybe you can add a vibration test to your routine.

[@disklamer]

Great illustration of the difference, that heat cam makes it all very real. The resistance between the connector and spring and busbar translates to heat. The exact material of the busbar/spring can make a big difference. Obviously WAGO uses spec materials, where your chinese knockoffs may use whatever is available, which may not be the best conductor ie. heat up more. This could even be batch dependent as someone pointed out. And not only are you creating heat, you are losing power. It would be interesting to see resistance / powerloss over each connector, you know, for science, and because the loss percentage translates directly to your power bill.

[@ypw510]

WAGO uses stainless steel springs and tinned copper bus bars. So does Ideal for their version of a lever connector. I believe the resistance isn't from the conductive materials used, but rather the contact area. I've taken apart one of these (from Ideal) and the contact area with a solid wire was really just the spring, a narrow point where the spring pressed against a tinned copper bus bar ridge, and the tip of the wire against the bus bar. I think there might have been better contact with a stranded wire, if inserted without twisting would have splayed flatter against the spring and bus bar. That being said, I'm using them and am confident that they're safe to use. The spring maintains a very consistent contact point. I've heard of criticisms that the wire can wiggle around or even slide against the bus bar, but that shouldn't matter as long as the spring maintains constant pressure against the bus bar. Power loss due to resistance is going to be dependent on the load. A good length of house wiring is going to be higher resistance than the connector. However, it's possible that a line is chained through several connectors. I've got a living room where it's chained to five additional receptacles using wire nuts, so each one adds up.

[@ncooty]

Great PSA. That cheap knock-off stuff isn't just crap; it's *dangerous* crap. It's like that for fuses, tools, wire connectors, pharmaceuticals, climbing gear, towing equipment... EVERYTHING.

So wire nuts, most likely when installed absolutely correctly, run cooler than the WAGO lever nut, but, really, that's to be expected. There's more contact area when the bare wires are twisted correctly inside the wire nut, while a lever nut has much less contact area. I bought a WAGO kit from your link and am happy with that purchase. When I need more or for larger gauge wire, I'll get them there again. Thanks, Scott. What a revealing comparison.

Truth be told, the amount of contact area with the bus bar and spring (which probably takes a little bit of the conductivity) is small compared to squishing wires together in a wire nut. But as you say "twisted correctly". I've had wire nuts where there was no practical means to pretwist given how little wire was left, and lining up three ends (including a pigtail) were difficult and one never made contact. At least with these it's very easy to visually see that it's fully inserted and clamped. However, testing labs have certified them for use with the typical 20A (or even more in Europe) that we use for mains power in the United States.

With the power running through the spring, it will cause it to warm, heated springs will lose its resiliency and lose the tight lock on the wires Thanks for the review and tests, I will be rewiring my girlfriends house here in Thailand and I was debating to go Wago or wirenut... looks like the best path is to use a mix based on loads and wire types Use the right tool for the right job :)

[@realvanman1]

One thing that might happen with the ones with the shared springs when the connection ages and oxidizes is more current might begin flowing through the spring and thus it might get hot enough to loose tension sooner than the Wago will. Obviously this is a non issue with actual wire nuts as the conductors are tightly clamped to each other, vs comparatively loosely against a flat bus bar.

[@charleshoyt8191]

I've used the Wago's for a while. Very good for tight areas. Make a video on the use of the "new to me" ferrule crimp connectors. Can they be used in outlets and routine electrical work? I use stranded copper wire in almost everything. Thanks.

[@peterbechard1900]

The first thing I thought about knock-off #1 was the direction you pressed to close the lever. It was in a direction that has you pushing in the direction that could result in having the wire slip out from the connection. I could see that really being a pain in the butt it tight areas. It’s electricity, just buy the best to remain safe.

[@WAGOCORP]

That's the idea. Because we patent everything, knock-off lever nuts have resorted to a design that is different than WAGO's. Our 221 connector was carefully engineered for the best performance and cannot be effectively replicated.

[@foogod4237]

Ironically, I actually like the reverse direction of Knockoff #1s levers, because it means that if anything pulls on the wires, it will pull the connector in a direction that _will not catch_ the levers and potentially cause them to reduce tension on the connection and let the wire slip out.

[@saltyroe3179]

​@@foogod4237I bought some IDEAL lever Connectors just to see how the preformed. They are easier to use because the levers are reverse of WAGO. The reverse levels may be helpful with some access problems. But..... I like and have used WAGO lever nuts for years. The high relative cost is easily offset by the advantages. My favorites are that lever nuts do not twist up the wires and makes a sure multiple wires are connected. In my collection of old technology are porcelain wire nuts made by IDEAL and extracted from a 1929 house.

[@GodlyNoghri]

@@foogod4237 I came to post exactly this. Plus, the direction of pull will impose an additional closing force vector on the lever (inside the connector), whereas the opposite is actually the case for even the true Wagos

[@davidkahler9390]

If you can get your hands on the Ideal version, I'd love to see that

[@LuLu_World]

would love to see a weight pull test on the terminations.

[@allentrench]

I have to have switched over to Wago,s. I have been using them for a while now. Are any of the knock offs UL listed? I know Wago,s are a little bit more expensive, but that expenses peace of mind, knowing that they’re not gonna fail

[@thespencerowen]

I’ve been using the knockoff 2 for about 2 months. I didn’t realize they were knock offs. I’m going to rip them all out next week

[@Verminator151029]

Great video. I have some knockoff ones as well, not sure what brand and frankly it's impossible to tell. I'll use up the knockoff ones for low-voltage 5-volt projects, and save the Wagos for the AC power.

[@stevenwisniewski]

Was the ambient temperature the same across all of the tests? I didn't notice any mention of it.

[@jonathanadams2623]

I bought Wagos online. Went into Amazon first to look and it was crazy. All the knock offs mixed in with the actual brand. It could be confusing if you arent 100% certain what youre looking at. I went to Platt in the end and ordered through them.

[@smashthings4fun]

Hey I got a video suggestion. You should do a video on hyper tough receptacles and light switches and test to see if they’re any good

[@amcoffee4me]

I have some of knockoff #2 (bought by mistake) and they are fussy to how well you strip the wire. If you don't strip the insulation enough, it is hard to insert the wire fully into the connector. With wire stripping length correct, they insert correctly and hold well. But I would never use them for any serious work. I use them in testing wiring for home built battery boxes, or other prototyping. For household wiring, use WAGO brand period.

[@grasstreefarmer]

Great video. I had been using knock offs and just recently bought a bunch of genuine Wago. I was confused when I took apart my knockoffs which are the same as your no2 because the spring seems to be the same as in your no1. The spring is joined on the bottom fixed side but the working sides are split. I looked more closely and yours are the same, you were just showing the non working side. We don't seem to have the reversed knockoff no1 here in Australia. People should also beware that colour is not a reliable indicator of what type these connectors are. The very cheap clone no2 is available in lots of different colours, not just the orange but alos blue, red, green, white, pink and probably others. Clone no1 can be found as Ojun OJ-26 connectors and they have inline models as OJ-28. They are pretty expensive though and in some cases Wago are cheaper.

[@briantorsell]

Those temperature differences made the decision much easier

[@alanrkanter]

As a homeowner with an electrical engineering degree, I will stick with wirenuts (after pre-twisting of course). I will use a WAGO in line if I need to join solid to stranded wires.

[@sasines]

Unfortunately there are many knockoff things on Amazon. I hesitate to buy something like this online due to the safety issues. I’ll go buy them at a brick and mortar store so I can see and touch what I’m getting. Hey Scott two questions. Why is there not a four port connector? Any chance you would evaluate the Ideal brand lever nuts? Thanks for what you’re doing.

[@markGibby]

What about the ones you can get from Lowe’s or Home Depot? Are they any good?

[@volkhen0]

I have my solar PV panels connected through Wago 221-613 which has two numbers printed on it. 30A / 41A. There is about 3,6kW flowing at noun which is about 15A. The connector doesn’t even get warm to the touch. Connected cables are 4mm-sq.. this connector can take up to 6mm-sq. which is 10AWG.

[@jnri9581]

The WAGO connectors are by far the best on the market. The quality is second to none. Ideal makes a connector where you push the wire into it. I prefer the locking lever.
