WAGO 221-612 Lever-Nuts 10AWG 2 Conductor Wire Connectors 50 Pack

Compact 2 Conductor Wire Connectors

These WAGO 221-612 Lever-Nuts accept 20-10 AWG solid and stranded copper wires in a tool-free lever design. The transparent housing lets you verify strip length and full insertion at a glance. Each pack supplies 50 pieces for residential or commercial splicing tasks. They are UL Listed and rated for 30 A at up to 600 V in building wire applications.

Practical Limits Of The Lever Actuated Standard

The connector handles only two conductors per port, so multi-wire junctions require additional units. It is rated for copper conductors between 20 and 10 AWG; aluminium or larger gauge wires fall outside the UL listing. Maximum voltage is 600 V for building wire and 1000 V for signs or luminaires, so higher voltage systems need a different solution. The 30 A current rating also caps the load you can place on a single splice.

Build Quality And Daily Use Implications

The compact black housing uses WAGO spring-pressure technology trusted since 1951 for vibration-proof, maintenance-free connections. Levers lift and lock without tools, and the mechanism is reusable — just raise the lever to release or reposition a wire. Transparent sides speed up inspection during installation and troubleshooting. The 221-612 model is larger than the 221-412 version to accommodate 10 AWG conductors.
