Review on Wago 222 412 Lever Nuts Conductor Connectors: Secure and Hassle-Free Wire Connections by Troy Arnold

These connectors replace the standard wire nuts on 20 to 12 gauge wire. They are firmly fixed on both stranded and solid wires, the wires cannot be pulled out. They are ideal for fixtures where 16-20 gauge stranded wire is frequently terminated to 12-14 gauge solid wire in tool boxes. Because the tension can be fully released by lifting the levers before inserting the wires, there is no risk of the stranded wire fraying or coming loose when attempting to force it into a spring-loaded connector without first tinning the strands. Because each wire hole has its own lever, the connectors can be fitted to the fixture's wires before being held overhead and connected to the room's wiring. This is a lot easier than trying to use regular wire nuts in the same application. The connectors are removable and reusable, which greatly simplifies maintenance. Wago connectors are also ideal for use in machinery or equipment where connections may be subject to vibration. You can't break free from the wires like a mother. Repairs and reconfigurations are easy.
