Ah yes, the Wall Nut.

The Wall Nut product we make is designed solely for use in solid wire, and copper only.

It does not utilize the same technology as the terminal blocks. The Wall Nut uses a leaf spring design, not the Cage Clamp. If you want to use a Cage Clamp, we make a product called the LeverNut, which is very cool. Same idea as the Wall Nut or any wirenut, but uses the Cage Clamp inside of it. It can handle 12-28 awg (I think, I don't have the spec in front of me) and solid or stranded. It also has a test port for probing with your multimeter.

The cage clamp connection is used in applications on just about every US aircraft carries, as well as all over the oil fields. These high demand environments show the robustness of our product.

It's unfortunate that someone had a problem. But that is a rare event.
