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

    What about the fixed wiring after the boiler - e.g. between the boiler PCB and room 'stats and so on? - if that's concealed in a wall (it usually is) then BS 7671 will likely require additional protection by 30mA RCD - can we be sure that that wiring isn't fed by semiconductors?

    But it could be a fault in the boiler as well ...


    We can't go assuming the manufacturer has got it wrong just because it means the job is a little more difficult.
