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 !

    Is having more than one conductor an issue, what about seven strand wire?

    It depends on the marking on the product. Following is a brief summary of the marking (see Table 2.1, page 26, in the latest 9th Ed GN 3, March 2022):

    If the connector is marked "sol", then you can't use stranded conductors (Class 2, 5 and 6) in it at all, unless the manufacturer has, as in this case, considered the use of crimp pin or ferrule.

    If the connector is marked "r" (for "rigid") then it may be used for solid or Class 2 stranded (not flexible Class 5 or extra flexible Class 6) conductors. Again, some products may be suitable for use with ferrules or crimp pins.

    If the connector is marked ("f") it is only suitable for use with Class 5 and 6 conductors.

    If the connector has no marking, it may be used for all stranding classes of conductor to BS EN 60228, i.e. Classes 1 (solid), 2 (stranded), 5 (flexible) and 6 (extra-flexible)
