    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?

    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.

    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?

    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.
