Wago connectors with too many wires

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 !

  • Then it is a good thing I have a selection box of connectors to pick and choose from 

    Around twenty years ago I was doing electrical work and kitchen fitting for a kitchen company who started supplying some small round under wall cabinet lights that took a compact fluorescent lamp. These had push fit connectors built into them and the manufacturer said they could be wired with flex, so long as you tinned the conductors.

    Because they were so fiddly to wire I took to prewiring them at home, so I could get them in quickly back on the job, I remember sitting at the dining table at home on a Sunday evening wiring lamps for the next morning and getting told off for the smell of flux in the air.

    This went on for a couple of months and probably half a dozen kitchens, then I was told the other electricians had all refused to install them, I went to do the electrical work for a kitchen that some of the others guys were fitting and they asked why I hadn’t complained about the lights and refused to fit them like the other electricians, I explained and told them what I had been doing, the fitters laughed and said that explains a lot, apparently I was the only electrician with a soldering iron.

    I have seen all sorts of variations in manufacturers instructions, for example Ideal connectors take seven strand conductor:
