Wiring a ceiling fan

While installing a bathroom exhaust fan using the lever nuts, I locked each one onto the appropriate wire on my bench, then just made the last connections up in the unit, with no worries of dropping the wire nuts or putting them in wrong.

As a DIY, these things are fantastic. Saves a lot of time, very easy to use, & reusable if you need to make any changes. I strongly recommend them!

They are very easy to use.

Easy to use

I had been reading reviews on some wire connectors that popped up in my feeds and the general recommendation was to stick with the original Wago 221 lever-nut connectors. I happened to have a wiring project at hand and bought this small sampler box to try them. OMG! These things are brilliant! They easily accommodate a variety of wire gauges and are easy to use and install. I think they take less time to prepare and install than traditional twisted wire nut bundles. Best of all, in an electrical box that is both a junction and contains switches or receptacles, these things are incredible at saving space, especially if you are also trying to include bulky items like dimmers or home automation smart switches/outlets. Your ground wires and neutrals can be connected and grouped neatly together in an easy-to-trace row of flat connections and pressed out of the way to the back of the box instead of the giant wad of twisted wires finished with a huge wire nut (and sometimes electrical tape) that tend to consume a huge chunk of the valuable real estate inside the electrical box and often requires you to squeeze the switch/outlet into the tight remaining space. These clever lie-flat lever-nuts leave plenty of room for the switches or outlets. Connections are quick and easy and almost flawless every time. You barely have to strip any insulation off the end of a wire for connection. In this case, it is almost less is more. I have been frustrated many times by a wire losing contact in that twist under a wire nut - or a short when a wire is inadvertently contacted/pierced as the switch/outlet is screwed in place. Often the wire shorts are difficult to trace and identify, and a pain unpacking and unbundling and re-twisting the wires together (or mending an inadvertent piercing of the wire insulation. Not a problem with these ingenious connectors. The assortment comes with 2, 3, and 5 wire connectors. I thought I might need to connect more than 5 wires, but that did not prove to be the case. If it were necessary, two connectors could be easily daisy-chained. I encountered a couple of 4 wire connections that wasted one of the slots of the 5 connector lever-nuts, and I momentarily wished there was a 4 wire connector - but apparently, that doesnt exist. While I kind of hated wasting the extra wire slot, I didnt lose any sleep over it. I liked these 221 series Wago lever-nuts so much after trying them out on the current wiring project, I have since purchased a larger assortment pack as I dont want to ever run out because I dont plan on using traditional wire nuts ever again! And I dont want to if I can avoid it! Thank you Wago for a great product, and these assortment packs are a great way to get started using them. While I havent looked, I presume I can purchase bulk packs of a single-size connector like you can with traditional wire nuts if I find I am using a lot of one size. But, that is a problem for another day...

These Wago connectors are everything I have read about! They are simple to use - PERIOD!! You cannot go wrong with these and the price for this assortment was reasonable. They make DIY projects smoother and safer and take all the guesswork out of which color twist on connector to use for amount/gauge of wires. Also, there is no doubt about whether you have a solid connection, like there is with twist on connectors. For DIYers, these are perfect! Obviously, if you are building a new house then using Wago connectors is not cost-effective. My one recommendation is to wrap them once with electrical tape to keep the levers closed (see pic). This is not because of any issue with the connectors, but instead, it is because if you do not have a good technique (which I do not) for folding the wires back into the box, then while you are jamming and cramming them in, youre likely to flip some of the levers up (open) by accident. It is just a little added insurance, just like when people wrap electrical tape around their twist on connectors.

Easy to use.

Easy to use…strip the wire, insert into slot, close the clip and the wire is secured. Traditional wire nuts have a tendency to fall off from road vibration and these will hold your wiring together nicely. I use these when I replaced my RV ceiling puck lights and in the future replacement of the pucks will be much easier with these clips.
