I'm always on the lookout for things that make my work quicker, easier, more reliable, and last longer.
Lately, I've started using something that ticks all the boxes: Wago 221 connectors.

Wago connectors, also known as lever nuts, are a great way to connect two, three, or five wires together.
Flip the lever open, shove the wire in, flip the lever closed.
They're super simple.
- Voltage rating (nominal/surge): 450V/4kV
- Conductor size: 0.14 - 4 mm²/24 - 12 AWG
- Approval: UL 486C
- Availability: 2-, 3- and 5-wire connectors
Wago connectors offer a fast and effective way to make safe and secure connections for indoor use or within a junction box. They are not waterproof so cannot be used outdoors or in damp conditions, unless you use a Wago Gelbox, which will then offer IPX8 levels of moisture protection for the Wago 221 connectors.
I find that it's the 2-conductor Wago 221 that I use the most, but I've found it handy to have the 75-piece kit that offers the 3- and 5-conductor versions too.
Note that there are a lot of clones and copies out there, but in my experience, they are nowhere near the quality of those offered by Wago, and I recommend you steer clear of them.
