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!

    I was referring to 7671 & 61439 in regards to type tested assembly, 60898 is just a device standard isn't it?


    It may or may not be ' immediately dangerous ' my point is I cannot know it is not because it has not been tested of approved in such scenario.


    MOT's have a list of defined faults and actions we do not, when you get your MOT certificate (or not) you get a specific number such as (1.1.c.1d)  for example.


    I don't come across many EICR's that list the actual regulation, I personally do it mainly because it raises less nonsense when the installation does not pass.


    We cant control the nefarious actions of others and I wholeheartedly agree that generally EICR's are naff, usually a satisfactory is a good indicator that it it anything but satisfactory to current regs.


    I did not think for a moment it was personal Dave ?
