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

    Hi Lyle



    Washing machines and similar appliances have used phase control etc. of their motors for many years, yet I have not heard of any accidents due to RCD failure because of leakage. Is this just luck or is it because the design is adequate?


     


    No, you won't have heard of any issues with RCDs with phase control.


    Quite simply because the Type AC RCD is unaffected by Phase Control - see item 1 in Figure A53.1 of BS 7671
