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

    ADS should provide shock protection for a fault inside it.



    So to my mind, it is all about blinding. I await a response from the manufacturer.




    Well, yes ... selectivity? ADS may well not operate for faults of a few mA to Earth ... which in themselves are not always particularly dangerous of course, especially if they are "mapped" onto the Neutral because of an N-E fault from an ELV source with a voltage low enough not to drive that current through the human body.. but we know this might be sufficient to affect the operation of an upstream Type AC RCD ...
