Type A rcd . EICR coding ? etc

aligarjon
Hi Guys.   Not been on for a long time, just had a bit of a search and couldn't really find anything so thought i would ask and see what you all thought.


1.  Are we or will we be coding type AC rcd's if there are LED's or induction hobs, lots of electronics  etc  present.

2. How much DC leakage does it actually take to saturate an rcd and cause  problem?

3. How much does a standard LED lamp or induction hob  leak ?

If we test an AC RCD with no load and it's fine then re-test it with all LED lights, induction hobs etc turned on and it operates correctly could we then say that it is ok with a note on EICR  OR EIC if installing any of the above.  


Obviously also on an EICR if the RCD then doesn't operate with it all on it becomes a C2 ?


Any thoughts

    No, my fear is that the boiler may trip a type AC RCD



    But the boiler instructions said

     
    Type A RCDs must be employed where additional protection is required."



    They did not say anything about tripping an AC type being a problem. 


    However, if there is some claim that an AC will be blinded by the normal function of the boiler, so disabling Additional Protection for all or part of an installation, then that Boiler is not fit for purpose as a "replacement", unless it has been made crystal clear, by the seller or reseller beforehand, of the significant constraints regarding extra costs and warning of the alledged risk to safety of continuing to use an AC RCD.


    I expect the instructions or advertising do not advise that AC type RCDs will be disabled by the Boiler or that it will trip an AC RCD.


    Back, really, to an earlier point being these instructions have been updated to the 18th, that is all. The Boiler and its components are likely not very different now to those installed a while ago. I do not buy into the manufacturers having a sudden eureka moment, after all they would surely have many years of data of their boilers tripping AC RCDs or blinding AC RCDs, if that were the case.



    Edited as Olympus Mons just referenced some instructions

    This seems like a bit of @r$e covering by the makers, just in case. They should not be marketed as "replacements" without full disclosure beforehand of any perceived safety issue.
