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 !

    There are millions of installations in the UK where these connectors are virtually useless, because older imperial sized cables have stranded conductors, whereas the newer metric equivalents have solid conductors, so they cannot be used on socket and appliance circuits.

    Use another product in the range suitable for rigid (solid class 1 and stranded class 2) conductors, such as 773's.

    Alternatively, most of the lever types are suitable for all stranding classes 1, 2, 5 and 6 to BS EN 60228.
