WAGOConnection Terminals 221-415 | 5 Conductors, up to 4 mm², Pack of 25, Compact Cable Connector with Levers for All Conductor Types Worldwide, Confirmed Application Safety

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.

If you strip the wires to the length shown on the side of the Connectors, they will not pull out!!! Great if you will ( even Might) ever have to do any troubleshooting!!! Imagine having to get just one wire out of a properly twisted together group of wires inside of a Wire Cap! So easy with these - I never use wire caps anymore!!!!! They stay nice and cool with rated Current through them!!!

They are expensive, but they make my handyman work so much easier and quicker!

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.

I came across these when I was looking at a video for testing an electrical circuit for current. The You-tuber used this as a connector between the circuit and their multi-meter. I ordered them and I am so glad I did! Connecting multiple electrical wires with a traditional wire nut is such a pain in the neck! Strip the wires, try to hold them together while you twist them together, trim them so they are not too long, and then use the wire nut to hold them together. With this, it is soooo much easier! strip the wire to expose a small amount, open the clip, stick the wire in, close the clip, do the same for each other wire you want to connect. No more fighting with wires, no more twisting, then twisting again. Ohh and if you need to remove a single wire, just open that clip. The rest stay completely secure. Worth every penny!!!

Excellent product and easy to use. Strip length of wire per guide and snap into place, that easy. Holds stranded and solid wires works great, make sure it's original Wago

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.

Work great and very easy to use watched a few reviews online before ordering great for diy projects around the house I guess these are huge over seas and starting to come around here and I can see why definitely going to use these on the remodel after I give my garage lights a few months to see how they hold up definitely recommending these for around the house
