WAGO 221 Lever Nuts 90pc Compact Splicing Wire Connector Assortment with Case. Includes 221-2401, 221-412, 221-413, 221-415

work great!!!NO more wire Nuts. I tape them after install to make sure they don't unclip shoving them back in a tight box.

Just discovered these in the past few months and bought the multi-size package. Very pleased with them as they are quick and easy to use.

Did LED conversion on 12 fluorescent fixtures. Removed ballasts and rewired. The Wago connectors made it a fast and simple job. No wire nuts or electrical tape needed. Easy job despite high ceilings.

Awesome device

I am only recently discovered these connectors and as I am typically a doubting Thomas, I had my reservations. BUT!! Once I tried them, I was totally hooked!! I am in the middle of remodeling our home and as it was built in 1905 and let's just say it has been a daunting and slow process. Most of the delay has been retrofitting its electrical system, but these little gadgets have been a life saver! They allow a person to work in tighter spaces and often eliminating the need to replace an entire receptacle saving time and money! Follow the instructions on how to strip the wires and prevent slip outs, and your electrical DIY projects will be become far easier and be completed far faster!

I really like the WAGO 221 vs traditional screw-on wire nuts. It makes assembly, inspection, and re-work much easier. Small design changes are easily accomplished without disrupting other existing connections. By planning in advance, wires may be added later by just plugging in another wire.

I much prefer the way I join wires. They test out just as indicated, imo. They equal what I do in most ways. I like the strength of how I do things, better. Also, unless I'm waterproofing what I do, I'm not much slower than the different types of lever nuts that I've previously been given. Going to keep some around for emergencies. Just watch out, though. Most, if not all, have wire length requirements extending out of the boxes. Best to be sure you've enough wire facing out of the box when coming out after connecting a hot. On an initial, final, or any inspection, that ''turn over" could leave you a bit short, if someone were going by the letter of the law, imo. Keep in mind, I AM NOT AN ELECTRICIAN, but I do affair amount of wiring during most days on machines. I run off of a different set of rules, many my own, so the requirements of residential type wiring, plus most else for they're general opinions, I almost always look to the NEC, if I don' remember what exactly I did the last time, concerning one offs

Great help on projects!
