221-2411 Wire Connectors, Lever Nuts Connector , Electrical Wire Conectors Assortment Pack, Inline Splicing Conector With Case (24 PCS)

So far I haven’t found anything wrong with these things. Can be opened and closed repeatedly, and seem to handle the amp loads for circuits where I’ve used them (30a or less so far). They are simple and just work.

At the corner of Lego, Electrical, and Engineering Land is this product.

Easy to use, small and a very secure fit. No more wire nuts

I love Wagos and these appear to be genuine, HOWEVER the description is wrong. The Wago 221-2411 (which this is) has a max US wire size of 14 guage. If you want it to go down to 12 gauge you need the Wago 221-2401 (apparently). Will be returning as the description of the product was wrong (though it's a good product if 14 gauge is fine for you)

I will not go back to using the old wing nuts for wiring. These are so easy and convenient to use. I ended up buying more. So far, no issues with them.

These are my new go-to's for butt splicing. I really like the form factor on these. Choices are good.

If you have short wires in a box and need to run jumpers these WAGO connectors are the best way to safely use jumpers. They are so much better than wire nuts and take up much less space. They make a secure connection ( I always give them a tug just in case) and reall make secure connections.

ease of use. better grip on wires in my opinion.
