Now read the relevant REG(s) and determine whether or not this applies to say a DG 2-way stairs light which is supplied from the SAME supply by the same DNO via the SAME main fuse and cut out (but by different circuits). Does the wording of the REG(s) mention 'supply' or 'circuits'?
OR whether it applies to say a changeover switch which connects to the above SAME supply plus another SUPPLY from say a standby generator.
Then ask why is it that makers of boards e.g. Hager, Wylex supply RCD test labels with their RCDs but makers of GRID switches don't supply the labels you've posted above.

I'm pretty certain ( but not absolutely so since I don't have access to a boxfull and havent used them or 4 years... ) that MK gridswitches do come with stickers to fit onto the grids if you buy them in the box.. not as loose singles..
I posted this just to confirm there are these and also different worded versions available.
Not to start any confrontation.
Larger grid switches were once supplied with 400 v stickers, as this was more likely, due to greater loads and the need to balance over 3 phases.
However a single phase designer would avoid having two circuits in a switch.
A lot of 400v stuff comes without a 400v label and that is IN the regs,
The onus is on the installer to buy and fit them.
When you buy cable do they give you a harmonisation sticker
Again no because you may not need it
The onus is for you to buy and fit it
An rcd has to be tested so a sticker would be needed NEARLY every time
However that sticker is no good for a petrol station, it would be uneconomical to give you two types though so they dont.
If only for safety the above warning label is recomended.
As long as visible inside when the cover is off, I would say is suitable.

Isn't a 400v sticker only needed if Uo exceeds 230v?
in a domestic situation it's almost impossible ( as well as inadvisable ) to have all lights on one circuit, so where there is a stair well with the need for 2 way switching it's inevitable that at least one switch would have 2 breakers protecting the circuits inside.. hence the need for a lable..
Yeah, however it is best practice to fit them where a U of 230v> wouldn't be expected.
Where does it say that?
yes
and if you buy an enclosure and a 400v contactor and a lot of other stuff.
You buy your own and you are responsible to fit it

It doesn't need to say that for it to be best practice
If you have 2 sockets next to each other supplied by 2 different phases then would it be best practice to label them as 400v between sockets?
So no 400v sticker NEEDED then?
Though 2 sockets close by to each other off different phases doesn't strike me as being the best of design.

In that case U could be expected to be greater than 230v
