WAGO 221 Lever-Nuts 75pc Wire Connector Assortment Pack with Case

Easy to use

Residential wiring.

These lever-nuts are quite compact. Initial use was for installing a ceiling light fixture. Wire connections were easy and very solid - no slippage or loose feeling to wires once the lever was flipped and the wires secured. In this case, the connectors were physically a bit smaller than the manufacturer-supplied wire nuts. Very pleased thus far.

I like the ability to use these in an install and have it be secure. Being a DIYer I’m not very confident in my ability to get a stranded wire around the solid core and secure it with a wire nut. These are easily secured and easy to check if they are secure also. The strip gauge on the side is a nice addition.

I had some of the Chinese connectors but the wires were able to pull out without lifting the lever so I switched to Wago and the difference is very clear! The box they come in is very nice too it comes with moveable dividers and strong latches, you can re-purpose the box after using all the connectors, very cool.

great product. I do a lot of DIY projects like changing switches and outlets. These connector make the job so much easier.

I like the latch vs the push connection. Makes using smaller stranded wire easier

One size WAGO connector fits most sizes of wires. Very compact. Very stable over time. Testing port permits voltage testing probe easy access. Can be used one-handed, or in tight places.

I have used the In Sure type wire connectors in my house with solid wires to great effect, and attempted to use them on the 12V wiring in my RV. For thicker wires, they would work somewhat, but with the thinner gauge wires they were useless. These wire connectors are perfect for use with braided wires, regardless of gauge (within their specification range). I would tape the levers before putting them behind the wall just to make sure they dont vibrate open while the RV is in motion, but aside from that they were perfect for the use that I had.

Where have you been all my life? Ive used wire nuts for decades. These are faster, visible secure connection, reusable, and less space taken up in the box. Wish I had found these sooner. There will probably be a use for the wire nuts that these replace, but right now I cant think of any. Buy the assortment ... In one box, I used the 3 wire to connect line, load, and box grounds, and two 2 wire to connect the load to hot and neutral.
