WAGO 221 Lever Nuts: Testing the Most Common Negative Feedback

I wanted to share some testing on WAGO 221 lever nuts to see if there is truly a design flaw, as pointed out by my audience, or just something to be aware of when using lever nuts.

  1. ???? Well done test. Thanks for making it happen. Your test along with everyone’s comments on taping are well needed. Wago hopefully is listening ????

  2. My knowledge of electricity was acquired when WAGO Levernuts was already established. I'm grateful for it because I can bypass learning how to use the older methods of how things used to be done. I don't understand why WAGO Levernuts has haters. I learned it quickly because it's so easy to understand.

  3. Never noticed that the level comes up so high, someone could easily trip the lever and the wire could come out. Maybe heat shrink! around it?

  4. If it doesn't take much force to partially open. It shouldn't take much force to close them back. Why not use a small rubber band to hold it closed? They make colored rubber bands for making bracelets. It could even make identifying your connection easier. A small piece of shrink tubing may also help with holding the lever closed.

  5. The next question would be how many pounds can a simple wire nut hold when connected properly compared to when it is improperly connected. I think 20 pounds is more than enough holding power unless You've got a ceiling fan in which case you should have a solid connection without any splices to hold the fan aloft separate from the wiring to supply power.

  6. Would you perform a similar test with a traditional wire nut? Curious what the failure weight is, using your same setup.

  7. I agree with all the one saying to wrap wago into electrical tape if the lever is something of concern. I used wagos after seing vids here, and i can confim in some cases, but honnestly if your lever manage to get up a bit, either it's not a problem or you're gonna force the box to get it done and then the lever will be pulled all the way out. So in any cases, electrical tape is your best friend. And if you are doing electrical job, you're gonna have it around in all cases, so that's a win.
    My main concern about wagos is the side they take because sometime, you have your switch, your cables, and there is really few space to put 3 wagos on each cable and get everything back in. I got the problem when changing a switch for a timer. But meh, i managed it anyway so….

  8. I like the Wago 221 connectors. If it was a real concern a person might tape the levers down with a wrap of electrical tape. How long will electrical tape hold?

  9. I've noticed this problem when I was using them. To solve it, I wrap it with electrical tape; 1-2 layers and that's all it needs. If ever you need to alter it, it is very easy to remove the electrical tape, do your changes, and wrap it with electrical tape again.

  10. In my experience WAGO nuts are 100% better than the twist on wire connectors. There's just no comparison.
