Lever-Nut,Wire Connector,Assortment Pack Conductor Compact Wire Connectors, 222-413(50)

I just finished wiring an addition to my house including a workshop. I kept changing the scope of the project which would have usually caused me a bunch of rework changing the wiring. with the lever nut connectors it was quick and easy. installing a ceiling light no problem just pigtail to the existing wiring and in a few seconds the wiring is safely and securely connected. Any time you want to change something it is a simple lever click away. I took one of these apart early in my project to see if something so easy could render a good connection. I was surprised at the robust connection inside there is a large surface area of contact with a powerful contact pressure. I even use these on my car, I put trailer lights in in a fraction of the time it would usually take. Considering the low price. As long as these things are available i will never use standard wiring techniques again.

I really love these products, however, I return these items for only ONE reason. I can not find anything that states they are UL Listed. I would use these for almost anything, EXCEPT for residential house wiring. In the area that I live has strict rules on electrical wiring. My AHJ [authority having jurisdiction] wants everything to have a UL Listing for electrical wiring. Either on the item or product documentation, without that, my AHJ WILL NOT not approved the electrical inspection.

To put wires together

I used these for my Lifepo4 ammo can project and then used them for all of my 12 volt wiring in my School bus conversion and they were great. I had a problem finding a big enough crimp connector for multiple 3 - 12AWG wires and wire nuts are a big no no in a moving vehicle. These came in really handy and I will be buying more in the future.

It looks like a knockoff of some better name brands (you know that German stuff), but close enough. Safety-wise, if you trust the Chinese safety mark (I do), you can rely on them. So for the money and function it is a good one to have. Other options of using a terminal block or splices are potentially problematic because of size or reliability. This is small, safe if used correctly and very easy to use. Actually it needs no tools to install, only the bare wire ends. Once you installed them, you can forget about them.
