221-2401 | WAGO Lever-Nuts® Inline Splicing Connector | for Solid and Stranded Conductors | 2-Conductor with Operating levers | 20-12 AWG | Transparent housing | White Cover | [Box of 60 Pieces]

beats wirenuts.

like other wage products, this item is invaluable for connecting single wires to power such as overhead lights where you are working on a ladder or other intensive circumstances.

Whats not to like?

Ive been replacing smoke alarm heads and these work well, along with multiple conductor Wago connectors. So much simpler than wire nuts and connection is easy to see and test.

I had originally purchased a variety pack of Wago lever nuts to use for smart switch installations in my home. The variety pack contained the side by side 221-412 style for two wire connections - I quickly depleted those as many smart switches have wire leads and the side by side style quickly got used up for line/load black leads and neutral white leads (for those switches requiring neutrals). Looking to replenish the side by side two wire connectors, I instead sought out this newer (at least to me) 221-2401 inline style connector, as I had seen it in use in a couple Tech Tuber smart home installation videos. I found though that based on the specifics of each individual installation, both the side-by-side and inline styles have their particular use case. I actually prefer the side-by-side style if installing in a busy box - the side-by-side tend to lay up better in my opinion when pushing the wiring back in to the switch box. The inline connecters are preferable in a couple situations, including installing an overhead light fixture or extending overly short wires in a switch box. For overhead fixtures, the inlines are easier to snap on to the house wiring, and then bring the fixture up to the open end of the inline connector and snap the fixture leads to the house wiring (the side-by-sides have you fighting gravity a bit as the fixture leads need to be brought parallel to the side-by-side connector). I also have a switch leg switch box where the original ground wire was left overly short by the original electrician when the house was constructed - these inline style connectors are perfect for attaching to a short wire first, before any other connections are made, and then the wire lead from the smart switch can be easily snapped in - in this case, with a short house wire, the inlines dont fight being pushed back in to the box like they do when using the inlines with reasonable length house wiring. So in summary, both these inlines and side-by-sides are good and have their uses - I may have gotten a lower count inline box knowing what I know now, as I think the frequency of use of these will be lower than the side-by-side usage.

Best way to connect wires. It just works.

Reviewed tests on these units and they passed with flying colors! Safety and convenience along with the space-saving application improves upon any wire nuts! Reusable too. Accommodates both solid and stranded wires. Most remarkable results on tests for connective strength and temperature resistance. No more bulky splices.

Easy to use and reuse. Works with braided and solid wire or a mix of both types of wire. They are better than wire nuts and much faster to connect. Plus they hold the wires very secure. Use them once and you will be impressed.

Product was easy to use and sped up the wiring process.

Had a short feed to the breaker in my box and these were so clean for the extending to the breakers. Low clearance obstruction, great current load carrying.
