Older boards and availability/compatibility of devices

psychicwarrior
I know, I know, its been a subject of many threads over the years...but I am bringing it up again.  More a moan I think over the inflexibility (perhaps with good reason I accept sometimes) at times.


Old Volex board - not even split load...all MCB.   In good order, all aspects look lovely.   Ideally, time for a board change....well if you think so ;-)


Now then,  some minor works (circuit extension) would dictate  the requirement for RCD protection.   Solutions, shift the circuit to small outboard BS61008 enclosure; new board...or source and fit RCBO, which seems perfect and is the most cost-effective and simplest...other than...it seems that using another manufacturer RCBO is seriously frowned on... by Volex at least (and I am sure others).   Well I've known this for a while, but never faced a situation where doing so would be the most feasible option.


Is it really that bad to fit another brand device into an old board...what really are the *real* safety risks if the thing is secure and fits.  I cant really think of any other than fluff - assuming its same rating etc and sits nice.


I've heard the phrase type tested and I take it that means that everything in a consumer unit was tested to perform to standards etc when it was made up.  Then putting in a different RCBO means that is now 'broken' as such.


My question and I am just trying to understand the technical and regulatory issues here:  is it not possible at all, to issue a MEIWC to current Regs as a result of putting in a different branded RCBO (I cannot re-do the type testing etc of course!) and where might/is that prohibition backed up in the 'frustrating' Regs Book please ?

    Actually it is not even clear if it is always deemed to comply when all the bits are bought from the same source.
    an example of more restrictive conditions.

    Although we do supply all our components as separate items on our invoice, we can and do ship the the components already assembled, if you wish us to, at no extra cost. Where the resulting Distribution Board, as designed by you, is not certified to BSEN61439-3, it should comply with BS7671:2008, AMD3, 421.1.201 and/or 133.1.3.

     




    Which I read as ' you decided what to put in it, so it is your responsibility'.

    And of course it will be fine in practice, and even if it wasn't it is not non compliance with some EU standard that matters, but the fact it has burnt the wall paper or whatever.
