I used the Wago 221-613 level nuts to connect my grounding environment together.
I stumbled onto the mat HD when buying wire. I never saw them before.
! used 10 ga stranded wire for grounding.
This allows me to disconnect/reconnect as needed without losing wire length.
.
I bought some of those new type of wire nuts. Have not used them yet. I think the key to using them for neutral and hot is to strip them to the proper length. I wired my house about 10 years ago using traditional wire nuts but if I have to add or do any repairs I will use the new Wago ones.
I bought a nice crimper a while ago. For years I used those plier type. This crimps things much better. I recently replaced a motor on a drill press I rebuilt and i used the new crimper. Worked well. Glad I bought them. The crimper has removeable jaws that make all kinds of connections.
Another tool I have never seen.
My hand strength had never been great, and going away.
The lever nuts had a nice positive lock feel.
There are videos on youtube about the pros and cons of the WAGO. Some say it is the best thing since sliced bread and others not so much. As with most things it is learning how to use the properly is the key. Review some of the videos so you understand exactly how to use them. Seems simple but as usual the devil is in the details.
Interesting video. I was wondering about the performance aspect.
I am using the connectors for ground only.
I got 0 hms across the Wago 221, but I was not pumping 20 amps through it.
The fact the Wago 221 shows a thermal signature is concerning for power side connections.
I tend to use dielectric grease if I am worried about corrosion or air gaps.
I’d generally say they’re the best thing since sliced bread.
My (naive?) hope is that they’re good enough for ~everything you want to do if you don’t know enough to care…and that’s basically rang true in any use case I’ve put them towards 
You’re on the right track. Contact resistance means power consumption. Power consumption means heat. Too much power consumption at any point can produce melting if a component is not made for that power consumption (whether its plastic or metal!)
I’ve not been convinced that those Wago connectors can produce enough contact compression (reduced resistance) for higher current circuits. However, they are very good for low current/low voltage circuits (if you have room for them.)
Be careful. Some “ground” connections are meant for diverting heavy currents. If your connector breaks down before the breaker trips, you could have added risk at that point.
For simple static grounding circuits, you will be fine with Wago connectors. BTW, you don’t need heavy wiring for static discharge grounding (as I look at your included photo.)
Thanks for the heads up. I will keep and eye on the connectors.
I went with the wire recommended by my electrician who has a lot of industrial experience.
I don’t mind being over designed and it fit without issues.
Why are you using dielectric grease? Dielectric greae is non conductive. You want connections to be conductive. Where exactly are you using the dielectric grease?
In practice the Wago is likely faster. As in the video twisting the wire nuts does not ensure a good connection. The video was made in Germany and Wago (or clones) seem to be the standard there.
Actually because we always used it on a MicroSprint that saw dirt and power wash abuse.
So one premise was correct ( corrosion ) but conductivity was not.
Today’s education. Thanks !
