Whilst installing a new set of interlinked smoke / heat / CO detectors here, I thought I'd try Wago connectors for the first time.
I really like them.
They are compact, neat and easy to work with.
This picture shows four 1.5 3+E cables terminated in a small neat connector box.
This box allows for 3 connectors of either 2, 3, or 5 ways at the top ( eg L, Sw.L, N, or L, N, and Interlink as used here ); and a separate 5-way earth strip as shown.
The same thing with screw terminals would be pretty scrappy, difficult to wire, and rather bulkier.

<waits for the obvious comment on the installation...>
I'll add the comment myself: it's the colours of the wiring.
I'm being a bit naughty using old-coloured 3+e ( Red, Yellow, Blue ) which was depreciated back in 2006.
New wiring after that date should use the new Harmonised colours ( Muddy brownish grey, Muddy brownish grey, Muddy brownish grey ).
I happened to have a full drum of old-colour 3+e which was quite expensive when I bought it years ago.
And now I have a need for 3+e.
This building is 1970s construction, and already has a mix of old and new colours.
So I'm not going to purchase a new drum of cable, I'm going to use what I've got.
As is well-known, electrons are colour-blind.
