Can you take 2 phases to a consumer unit?

If you really could not tighten them, use pan head screws and screw them back so they are nigh on flat against the wall, and then hang the board.

As to your first question, there are many occasions where DIs get involved in instalations that perhaps they should leave alone.

What exactly is a domestic installer, it sound like an inexperienced electrician? Is it like having P plates on your car after passing a driving test

back to the OP

The correct installation could so easily have been 2 x single phase boards with RCBO's

Nice one matey.

Would you please share what they say .................. this has been an interesting thread ........... so far

Yes I will, most certainly

 

[Gigsy]

So there not lower than the earth and neutrals bars

exactly, the screws are behind the bars at the top of the board

 

[Gigsy]

In 22 years of being an electrician I have never come across a fuse board that I could not tighten the fixing screws in.......

Very bad design i know

Good point, I stand corrected. There is no such thing as a domestic installer, I guess. I was replying to another comment. I think we were referring to somebody unfamiliar with working on a 3 phase supply

I agree, that would also have been a better design

thank you

It does not require a 400v notice as the nominal voltage does not exceed 230v.

There were some produced 23 years ago.

 

[Gigsy]

thank you

I can't get the board off the wall tho. That could have been done before it was wired i guess. I will take note in case i encounter a similar situation.

I think a warning sticker is advisable because there is a potential of 400V between phases inside the enclosure.

Anyone working on it should undertake safe isolation procedures.

Assuming it’s correctly labelled I see no reason why not. 1, 2 or 3 phases are all under 1000v, and the main switch itself is rated at 400v. Proteus used to make a 3 phase busbar for their single phase fuse boards so they could be used for that purpose, I assume it’s still available.

I think so did/do Hager.
