If it was a multi phase dB it would be designed as such, not bodged with two phases at the will of someone who ought to know better.What makes you say that this board is designed for a single phase?
If you look at the specs of consumer units, you will find they do not state they are designed for a single phase?

Just googled "electrical improver" tells me SFA

We took the bottom screw out, the top screws are meant to be loose, you hang the board on the two top screws, then secure it with the bottom screw.
Thats an interesting method of installation. I think you'll find that all fixing screws are meant to be tightened, not just to hang loosely in?

Looking at the way this thread is going I don't think anyone will come up with any regulations that prevent you using a 'single phase board' for a multiple phase installation. If it had a clear label on the lid stating that 400v was present, and that both isolators should be switched off before removing the cover I would be ok with it. It may be rough and look like a badgers nest but its not unsafe in my opinion.
It's hardly a common type installation with 2 isolation points when 1 will be the norm, imagine a Domestic installer or Eletrical improver turning up to do some work, only to find two live conductors in what is a fter all an enclosure designed for a single phase supply.Why is it very dangerous in your opinion?
Why? you might wish to improve your installation skills Gigsy. The top fixings are desgnedto be proud and not screwed tight until the Unit has been sited on the wall, and then and only then should they be screwed up tight along with the bottom fixings.top two are not meant to be tightened
Looking the board up on Contactums website it complies with BSEN 61439, which states:
The new IEC 61439 standard applies to enclosures
for which the rated voltage is under 1000 V AC
(at frequencies not exceeding 1000 Hz) or 1500 V DC.
So this board can be used for a 3 phase 400V supply then?

You can argue all you want, but in essencee that is what it is, a Consumers unit desgned for one supply with one singe point of isolation.
So the main switch is rated to 400v, and the enclosure as a whole is rated up to 1000v, Im not seeing any major issues here.
