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

    But any normal ("AC") RCD will sense all of the waveforms except 6,8 and 9, just at about twice the RMS current that it trips on a pure AC.


    So are you saying that in those cases, i.e. not 6, 8 and 9, in effect a type AC RCD becomes a 60 mA one?


    Mike, can you please explain why type AC ones trip when a VSD is turned on.
