Can you take 2 phases to a consumer unit?

[Gigsy]

Hi,

I am training to become and electrician, I have passed my C&G level 2 exams. I am working as an electrical improver.



I came across a consumer unit today, which has two main switches and two phases L2 and L3 supplying it.



Does this board comply with regs?



Can you take 2 phases to a consumer unit?

Is it rated for 400V and 25kA?

There is a single point of isolation at the main DB.

It is just a consumer unit. A metal box cant be rated for 400v.
The switches are rated correctly for the voltage and current they are being used for.
There is a 400v warning sticker on it.

Oh actually I can just about see it now. I mean the phase colours.

The cable dressing police will be along in a moment to comment on the untidy cables....

Oh actually I can just about see it now.

The right switch they are using a black conductor L2, the left switch they are using a grey conductor L3. Both conductors are identified as line conductors , by brown tape?

Which is where?

An enclosure and assembly absolutely can be rated for 400V or not as the case may be.

Ok well I am thinking why are there three neutrals on the first block on the right does this mean the neutral will be switched off with the first main switch, it is a bit hard to follow where the three neutrals go.

 

[Risteard]

Also I notice that 6kA rated devices have been used.

Which is where?

At the front of the building
