WAGO 221 Lever-Nuts 36pc Compact Splicing Wire Connector Assortment. Includes (16x) 221-412, (12x) 221-413, (8X) 221-415

WAGOs were used when I replaced some lever light switches with some smart switches. Easy to use and install. Wish I had bought a pack with the 8-conductors because one of the original wire nuts had four wires going into it and I needed to add two more. The wire nut wouldnt hold onto all of those wires so I had to use one 5 connector and one 3 connector.

The best way to install these is to use the wire strip length diagram on the back of the unit and then cut and strip your wires to the same length. After lifting up the levers above each hole you are going to insert a wire in, shove the wire all the way in until you can see it touching the back and fold down the lever all the way down tightly. Pull the wire to make sure that it is secure. On stranded wire, try to avoid twisting the wire before shoving it in the hole to the rear. These are designed to be used on wire between 24AWG-12AWG but 12AWG and 14AWG work best. Only insert one wire at a time and lock it down with the lever before going to the next wire. Make sure to pull it to insure that you have it all of the way back and locked down tightly. The 221 series is smaller than the 222 series but, both are limited to the same size wire. I recommend these over wire nuts for tying solid copper wire to stranded copper wire 100%.

Great concept/product. I will never use wire nuts again. More expensive but saves time.

Very easy to use,I’m just a homeowner and I don’t do a lot of electrical work but I know wire caps are a pain and I usually use electrical tape to make sure they are secure. Which I found out on u-tube that’s a false sense of security. These lever nuts are super easy to use and you pull on wire they are secure. I will buy more.

Really like the product and easy to use. Far better than the twist caps I used prior.

I have only been using Wago Lever-nuts for about a year after seeing them recommended in a Youtube video. After about 50 years of using wire nuts for various projects I am well aware of their many shortcomings. A perfect example would be wiring up a light fixture in my house where the light fixture comes with stranded wire pigtails to connect to the single strand house wire. Wire nuts are unreliable when it comes to attaching stranded wire to solid wire. I just completed a project which required a bunch of connections of stranded wire of various gauges, as many as 5 wires coming together in a single connection, and the Wago Lever-nuts were a real joy to work with. Only a year of experience with them is not much but at this point in time I love them. One feature I really like a lot is the ability to lift the lever and disconnect a wire and reconnect it again very easily. Tends to make isolating and troubleshooting very easy. Also connecting stranded to solid wire is easy and reliable as is connecting different gauges of wire.

I had been reading reviews on some wire connectors that popped up in my feeds and the general recommendation was to stick with the original Wago 221 lever-nut connectors. I happened to have a wiring project at hand and bought this small sampler box to try them. OMG! These things are brilliant! They easily accommodate a variety of wire gauges and are easy to use and install. I think they take less time to prepare and install than traditional twisted wire nut bundles. Best of all, in an electrical box that is both a junction and contains switches or receptacles, these things are incredible at saving space, especially if you are also trying to include bulky items like dimmers or home automation smart switches/outlets. Your ground wires and neutrals can be connected and grouped neatly together in an easy-to-trace row of flat connections and pressed out of the way to the back of the box instead of the giant wad of twisted wires finished with a huge wire nut (and sometimes electrical tape) that tend to consume a huge chunk of the valuable real estate inside the electrical box and often requires you to squeeze the switch/outlet into the tight remaining space. These clever lie-flat lever-nuts leave plenty of room for the switches or outlets. Connections are quick and easy and almost flawless every time. You barely have to strip any insulation off the end of a wire for connection. In this case, it is almost less is more. I have been frustrated many times by a wire losing contact in that twist under a wire nut - or a short when a wire is inadvertently contacted/pierced as the switch/outlet is screwed in place. Often the wire shorts are difficult to trace and identify, and a pain unpacking and unbundling and re-twisting the wires together (or mending an inadvertent piercing of the wire insulation. Not a problem with these ingenious connectors. The assortment comes with 2, 3, and 5 wire connectors. I thought I might need to connect more than 5 wires, but that did not prove to be the case. If it were necessary, two connectors could be easily daisy-chained. I encountered a couple of 4 wire connections that wasted one of the slots of the 5 connector lever-nuts, and I momentarily wished there was a 4 wire connector - but apparently, that doesnt exist. While I kind of hated wasting the extra wire slot, I didnt lose any sleep over it. I liked these 221 series Wago lever-nuts so much after trying them out on the current wiring project, I have since purchased a larger assortment pack as I dont want to ever run out because I dont plan on using traditional wire nuts ever again! And I dont want to if I can avoid it! Thank you Wago for a great product, and these assortment packs are a great way to get started using them. While I havent looked, I presume I can purchase bulk packs of a single-size connector like you can with traditional wire nuts if I find I am using a lot of one size. But, that is a problem for another day...

First time I used them and Ive been wondering why I couldnt think of these.

This has to be the single best timesaver EVER when it comes to electrical wiring. I used these to re-wire a car trailer, as well as my shed…12V to 120V, covers everything! These things rock! Pay attention though, only the WAGO brand is actually “UL listed“… While you may not be subject to inspection with any of your work, I highly recommend spending the extra money for this level of quality to CYA!!
