WAGO 221-415 Lever-Nuts 5 Conductor Compact Connectors 10 PK

Great for wire protection claps and holds tight. Better than any wire nuts. Works good with solid core wire and stran wire. Should wrap with black tape to make sure they don’t accidentally open up. Easy to always take apart.

I purchased these to make myself a testing box to allow me to have multiple connections coming from a battery negative terminal and the ease of use allows so much time to be saved, simply push the wires in correctly and lock them down to make a good quality connection. This isn't the first time I've used Wago connectors and while they're not cheap, I've always found them to be value for money as you can come back after some time and the connections are still as good as the day you made them.

I did some remodelling and some of the outlet boxes were tight with a few sets of wires. These made work easy and a bit more compact. Definitely recommend over standard wire nuts as you can visually see and physically test that the wires are secure. I use some electrical tape to wrap around the body to help keep the levers closed, especially when the wires need to be stuffed back with force into a tight outlet box.

fantastic things especially for changing old light fittings for new ones - this is the second pack I have purchased brilliant

These connectors are the Cat's Meow. So easy to use and saves space in the electrical box. They are CSA approved (will pass electrical inspection) and are safe and better connector than barrettes.
