Just spotted this:
Probably a bit more usable in a number of situations...
Must admit I had not spotted the Wago "buttons" before - I was looking at one of the boxes the other week thinking "what are they expecting these slots to engage with?"
(before I shrugged and screwed through its base into a joist!)
But beware it doesn't take the older 222 series, it's for the newer slimmer 221 series
By "manly" I was expecting something in cast iron :-)

Ah, I initially bought a assortment pack, to see if I liked the system, which came with some "buttons".
I had a sense of deja vu all over again when I saw the email from TLC about them. I eventually recalled/found where I saw them first.
That's actually a useful box!
Interesting to see that they have a new design of lever connector. I have to say that I use far more lever connectors than push fit ones (but I am not doing much with t+e).
I have tended to use the push-fit type for commoning earths in boxes with multiple two- or three-way lever connectors, meaning I have more earth wires than could fit into a five-way lever ...
Somehow I still don't trust these over traditional JBs, crimping or soldering. Are there any concerns about long term reliability - especially oxidation leading to a bit of resistance leading to a bit of heat leading to ... ?
Know someone who used to do HVAC install, he much preferred cage clamps in lever and DIN format to screw terminals, reckoned he saw a lot less toasted connections , screw terminals prone to loosening with vibration in the conditions.
The push in wagos seem to bite into the copper quite well, they also shroud the whole connection which ought to make for less oxidisation.
They're certainly very hard (impossible?) to get off again!
They are gas-tight, claim similar* contact pressure to screw terminals, as they've been around since 1977 someone should have noticed any problems by now.
[*] which presumable does mean slightly less, otherise they'd claim better rather than similar.
Just twist back and forth while pulling.
A twisting action does it...
Thanks, I'll try that next time. Further wiring required in the barn once the weather warms up, so I'll have a chance to experiment.
