WAGO221-415 Lever-Nuts 5 Conductor Compact Connectors 50 PK

If you want the absolute best wire connection for 2 wires, a wire nut is hard to beat. But once you start connecting 3 or more in a small junction box, the Wago lever-nuts are the way to go. They are UL approved, so you know they’ll handle the rated amperage, and I’ve seen them tested to double the rating without failure. Every 12 and 14 gauge wire in my home is connected by them, and I’ve added the 600 series lever-nuts for 10 gauge/30A circuits. I still use and trust wire nuts; they are proven technology. But for most household wiring, Wago works as well and is faster and easier. I’m sold on them!

I love these things. They are much easier to use than wire nuts. They clamp in the electrical wire very firmly and avoids the issues of wire nuts where the wires can come loose of the wire nut, especially when using different gauge electrical wire. Researching these on YouTube there are several safety tests showing that they are very safe to use, and many times outperform traditional electrical wire nuts.

I have been doing DIY wiring for 60+ years and these allow me to confidently and neatly make my connections and minimize box fill to meet code. I have about 10 years of experience with this product and yes, there are haters out there that swear the old "twist em and wire nut em" is the only reliable and safe connection. I have had plenty of open neutrals where someone who preceded me thought they had enough twists, but one white wire fell out. Not with these. You can feel the wire click in and clamp securely and I DO give them a tug, but always approved by the inspector and no failures.

The product is beyond great - I don't know how I ever lived without these things for use in electrical junction boxes. No severe pain from twisting multiple wires in a wire cap (I have carpal tunnel), they have two test ports for a probe, and you can apply them to form circuits literally as fast as you can strip the wires in a junction box. These are just better in every single way than even the push connectors made by Wago or Ideal. You can use them with wire sizes ranging from #20 down to #12, with both solid and stranded wire. They also sell a higher amperage version (221-615) rated at 30 amps that supports #10 wire.The only downside is cost, as these are obviously significantly more expensive than bulk standard wire caps. However, the expense is quickly made up with the reduced labor in installing them - as far as I am concerned, this offsets the extra expense. Plus, you never have to worry about a bad connection or broken wire resulting from a badly twisted wire cap.

Installing smart switches and some new lighting fixtures. Will never go back to twist-on wire nuts. These save space, are simple to install, and simple to remove. They make great electrical contact and you can be sure the connection is solid, and never have to re-twist or worry about loose wiring. Not sure why WAGO doesn't have a 4 position lever nut available, I bought a knock-off brand. Try them, you will like them.

Work great will work on solid wire and stranded, and can be removed easily

Great connector

I used these for wiring a home made electric go kart. They're very handy for distributing power. There are always a lot of things which need various kinds of power, and these by far the easiest solution I've seen. In particular, most alternatives don't do well with varying wire sizes. They're a lot quicker than soldering or crimping, especially in tight spaces too. Being able to easily+quickly remove something is nice too.I especially like these clear ones (as compared to the gray version Wago also makes) which let you see that the wire is definitely clamped in correctly. It's worth double checking that the jaws are solidly clamped on the wire, not just a few strands on the end or the insulation.
