In response to yesterday’s review of Wago Wall-Nuts push-in wiring connectors, several commenters mentioned their affinity for Wago’s lever connectors. I absolutely love using these connectors as well!
Actually, I like Wago Lever-Nuts even more than the Wall-Nuts. I use them mostly for lower voltage DC wiring, and they are far quicker and easier than using crimp-on terminals, screw terminals, or any other connector.
Wago makes the 222-series Lever-Nuts in 3 sizes: 2-conductor, 3-conductor, and 5-conductor. They can handle 28-12 AWG wire, both stranded and solid, and are rated up to 600V (1000V for signs and fixtures) and 20A.
To use them, strip 9-10mm (~0.37″) of insulation off your wires. The bottom of the connectors have built-in stripping length gauges.
Strip your wire, lift the lever, insert conductors, close the levers. It really is that easy.
Here’s a quick video demo:
Unlike the 773-series push-in connectors, 222-series clamp-down wiring connectors are reusable with all types of wire, not just solid core.
A built-in test port allows for voltage and continuity testing.
Overall, these connectors are amazing. There’s no downside to them that I could see. I really, REALLY like using them. The only reason I use the push-in connectors is because they’re slightly more compact. The 773-series connectors are also more economically priced due to their simpler construction.
Price-wise, a box of (50) 222-series 2-conductor connectors costs about $20. The 3-conductor and 5-conductor connectors are a little more expensive. In comparison, I recently purchased (250) 773-series 2-conductor connectors for under $10.
Model numbers: 222-412 (2-conductor), 222-413 (3-conductor), 222-415 (5-conductor), 222-500 (optional mounting carrier).
I purchased boxes of these connectors via Amazon. If you just want to try a few out, Wago 222 connectors are also sold individually via electronics suppliers.
Update: There’s actually a new version of these that is smaller and better featured – 221-series lever wiring connectors. It will be a while until the newer connectors are available in the US, but in the meantime we still very highly recommend the 222-series modules discussed here.
