Wago connectors with too many wires

Branta

The electrician who wired my (new) home takes the live feed to a light switch in each room (rather than to the rose).  Thus each room has a light switch back box with four neutrals commoned in a WAGO 2273 connector (feed in, feed onward, wiring to luminaire, wiring to spots).  I'm guessing the spots were a surprise to him as he seems only to have had a stock of 3-way WAGO connectors.  He's consistently managed to wedge four 1mmsq wires into a 3-way WAGO 2273.

I know this is wrong, the "extra" wire just can't be clamped like the WAGO design intended.  What is driving me nuts is that nowhere can I find it written down that it is wrong !

    Wow, I never expected to stir up this much interest ! But by far the best advice here is surely to ask WAGO.

    I'm a retired electrical engineer (which I realise does not make me an electrician) so when I discovered this I went to Toolstation and bought a selcteion of different sizes. The instuctions ("to be sold only with installation instructions") have an IKEA-like reliance on pictures and though it's very clear that stranded cores are not to be used, it really isn't clear that two solid cores shouldn't be pushed into the same way (but it's not easy to do, which should be enough of a clue !).

    Interestingly, since my original post I found behind a triple switch (bedroom with spots and main luminaire, plus en-suite light and extractor fan) SIX 1mmsq solids commoned in a 3-way lever-type WAGO. Now the lever-type WAGOs are qualified for stranded conductors, so (on the grounds that 2 solids are equivalent to one stranded, then this must be acceptable. Somehow I still don't think so !! As mapj1 says, the only authoritative answer will come from WAGO, but many thanks for all the opinions here.

    If you do, and get a response you can share, I think we would all be very interested.

    Yes, of course.  Right now I am getting very bored with their "hold music" so will probably need to wait for an email reply.  Indeed, I'll suggest they might want to join this discussion !

    I agree that the box that you showed is pretty clear that the three way connector is for 3 wires only, but the way I bought them from Toolstation (20 to 40 qty) only the 4-way came in a box with equivalent clarity - 2, 3, 5 way came bagged with a sheet that just wasn't as specific.

    Wago's autoreply told me they expect to respond in 24 hours.  They haven't.  I wonder if this has opened a can of worms at Wago ?

    I really only wanted to give the builder ammunition to get the electrician back.  But then it's over a year since I told him that the central heating has live signals passing through both blue and green/yellow cores (not a brown sleeve to be seen) and nothing has been done.

    As to my 6 wires in a 3-way "222" (lever type), I now have an 8-way 2273 in my hand, and even with its double-decker layout it is slimmer than the 222, so the ideal solution will be really easy.
