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

    Some salient points made here. The thing which strikes me is that the pyramid of responsibility has been inverted ...


    I have certainly benefitted much more from the discussion in this forum than from the manufacturers' advice.


    So it will have to be a type A RCD on the assumption that the boiler will trip a type AC one in normal service.


    In this instance, the extra £25 or so isn't much compared with a whole CH system, but a customer would certainly be unimpressed if a boiler change required a new CU and all that goes with it. At the end of the day, it will be the tradesman who gets the blame and not the manufacturer.
