Wago 221-415 Lever-Nuts 5 Conductor Compact Connectors 25 PK

I purchased the 2, 3 and 5 terminal versions of these. Like many others, I think they are a major advancement over wire nuts. Also, for many tasks these are much better than other push-in connectors because it's so easy to un-do and re-do the connections - this is helpful not just for electrical purposes but also for changing and re-routing the tangled nest of wires inside a crowded box. Some push-nut connectors have release mechanisms, but they can be much harder to use than the handy little levers on the Wago nuts. Another benefit of the lever-nuts is that you can easily test a connection before you finalize it, and there is no twisting & untwisting in the process, nor any need for separate clip leads etc. Some professional electricians might do this on the fly with the power on, but as a DIYer I never risk such testing with live house wiring. Set up proposed connection temporarily using the lever-nuts, go turn on the breaker to verify correct operation, then turn it off again and do the final cutting, stripping, connecting and box-packing. The next version I'd love to see would be double-row versions for six or eight wires - explained below. I've been converting most of the switches in my home to Z-Wave smart dimmers and switches. The two major issues with those are 1) the body of the device is much larger than the simple switches they replace, and 2) they require a Neutral pigtail to each switch. The small size of these Wago connectors makes it easy to push them back into the box, out of the way of the large smart-switches. Now, for the Neutrals, I sometimes use these Wago lever connectors to add the new pigtails, but often I need to add two Neutrals to an existing four- or five-wire bundle twisted together in a large wire nut. What I do then, is to un-twist the bundle, carefully separate and straighten the copper ends, and insert them into a push-in connector along with the new white pigtail wire(s). This is where the five-conductor Wago lever connectors can be inadequate - first because I sometimes need six or more positions, and second because spreading out all the wires in one long row is not always a good arrangement in the box. So in those cases, I use a two-row six or eight-position connector and do without the handy release-lever feature. Note that the Wago brand push-nuts (wall-nuts) are very good also, though other brands will do a similar job. Am important note when using push-ins vs. wire-nuts: I've found that when the wires are not twisted together as with a wire nut, there can be a lot of stress that tries to pull on individual wires, and this gets especially unpredictable when smashing a big wad of wires and connectors back into the box. So what I do is to pinch the bundle together and tighten it up with a nylon zip-tie about 1/4" to 1/2" (say 1cm) from the connector. This makes a strong bundle like wire nut would do, but it's shorter, smaller and a lot easier to modify later.

Wago is a great connector and it is reusable with little to no damage to the wire. Better than other brands

Great quality last

I'm building out parts of my unfinished basement, and doing the work myself so it will be completed in stages. I'm wiring in a few new circuits that will need to be active before all of the portions of the basement build-out are complete. Without this style of connector, I would be forced to remove the existing wire nuts to add any new branches as I reached subsequent stages. If doing this properly, that could entail disassembling an existing connection to properly add the new one back in, which, while acceptable from a code perspective, is certainly more complicated and less convenient. With these connectors, it's almost like you've energized an individual buss, and you're simply terminating new leads onto those busses. Now you can add the new branches one at a time without disturbing the original connections. They're not cheap, especially compared to conventional wire nuts, but the speed and convenience is hard to deny, and their application in an incremental branch addition situation like mine makes them well worth the price.

These connectors work great. If you need to change something they easily reconnect. They also save space in the box.

These 5 port Wago connectors make adding wifi enabled dimmer switches much easier in cramped junction boxes. Since my lovely electrical wiring is all connected at the light switches, I have to add jumpers to safely wire in a smart switch into the circuit, whereas the simple light switch I was replacing only connected the hot from one romex wire to another. This extra set of connectors added to 3 romex wires ran into the junction box makes trying to twist everything together under huge wire nuts AND fit in the junction box a real pain. This is where the multi connector Wago connectors really shine, as they allow easier connecting of all the necessary wires in a more compact and manageable package. Even though there is a big cost difference in wire nuts and wago connectors, the amount of time saved with Wago more than makes up for it, and I can easily go in to add something or change out the switch down the road much simpler without having to untwist or cut and re-strip a limited supply of available wire in the junction box.

My son introduced me to these "next generation" wire nuts. When you have more than 3 wires to connect and you are losing your mind with the old jumbo twist-type wire nut where you can't keep all the wires lined up and one keeps popping out, the Wago lever-nut is just an amazing improvement. Put a wire in, snap it down. Put the next wire in, snap it down. Soooo much easier. They cost more, so you wouldn't want to wire a whole house with them, but for those tight boxes with short wires and 4-5 wires all needing to be connected together, these will save your sanity.

works as expected.

Ótimo produto, encaixe perfeito dos fios, ótimo encaixe. Fica visual agradável e organizado.

Rien à dire c'est du WAGO

Ich nutze die Wago-Klemmen hauptsächlich für kleinere Elektroinstallationen im Haushalt. Die Handhabung ist wirklich unkompliziert: Hebel hoch, Leitung rein, Hebel runter – hält zuverlässig. Besonders praktisch finde ich, dass auch etwas steifere Kabel ohne großen Kraftaufwand einrasten. Im täglichen Einsatz haben sie bisher zuverlässig gehalten. Das Öffnen und erneute Verklemmen funktioniert problemlos, ohne dass das Material ausleiert. Gegenüber Schraubklemmen geht die Arbeit deutlich schneller und sauberer. Vorteile: • sehr einfache Bedienung • fester Halt, auch bei mehrmaligem Öffnen • gute Verarbeitung • ideal für enge Verteilerdosen • Verfügbar in vielen verschiedenen Größen (Anzahl der Plätze) Nachteile: • etwas teurer als herkömmliche Schraubklemmen Also: Eine praktische Lösung für schnelle und sichere Installationen. Für den Hobby- und Profianwender gleichermaßen geeignet.

Much tidier, easy to see. Make sure you always do a pull test as you insert each wire (important) Watch out for ‘look alikes’. Stick with WAGO
