Can you take 2 phases to a consumer unit?

537.2.2.1

i.e, this dual phase fuseboard does not comply with this IMHO

 

[Pete999]

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?

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.

Just googled "electrical improver" tells me SFA

Ask Siri?

Why is it very dangerous in your opinion?

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?

Yep agree with you 100%

If op says they don't need to be in why not use nails then

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.

top two are not meant to be tightened

Thank you for your objective opinion. I think I agree with you.

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.

 

[Pete999]

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.
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.
