EICR C3 mixed manufacturer breakers

Martyn
I know this will have been discussed in the past but we are on Amd 1 of the 18th now so I thought I would renew it.


The Best practice guides list mixed manufacturer breakers in a consumer unit or distribution board as a C3.


As far as I am aware Bs7671 does not have a Reg on it beyond manufacturers instructions and given EICR's are based on this standard perhaps it is justified on that basis.


Most on here will be familiar with the 16kA 'rule' in BSEN61439 Annex ZB or its predecessor BSEN60439 Annex ZA


I avoid C3's like the plague because they give all the wrong signals to a client and clearly by definition are for things which are a breach of the regs, I'm not too keen on the insurance risk of a C3 either.


My question here would be what fault rating can one apply to an enclosure where there are mixed breakers given a manufacturer will only have certified their equipment with their devices?


Enjoy!

    Reasonable codes are a requirement for a "qualified" inspector, with "experience" of risk at the correct level. Anything else is simply fraudulent for presumably pecuniary reasons against the unsuspecting and unknowing customer. If I came across an EICR with this coded as C1 I would contact the certifying body, because it is totally unreasonable.


    Only 1 answer so far to my questions, negative.






    Hi Dave,


    I believe rightly or wrongly that I could easily defend this gripping the bar if I needed to,.


    I guess my first argument might be something like , 'I'm not sufficiently technically competent to override two standards aimed soley at the protection of people nor am I insured to do so"


    As a rule of thumb I never do both an EICR and the associated remedial works, I generally use an external genius for such things.


    Cheers
