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

    As usual, a manufacturer's instruction Chris which is WRONG. Why does a boiler need a type A, in the case it requires additional protection? There are several points here. If bonding is in place to the gas or oil supply, why would the boiler require additional protection? Can THE BOILER introduce an external potential, which is not introduced by the gas/oil pipe? NO. Can the boiler produce a DC mains current? NO. Does it have a plug? NO. So what exactly does this instruction mean? It means that whoever wrote it has no idea about anything and providing faulty manufacturers' instructions should become a criminal offense both for the writer and the manufacturer with a prison sentence as the minimum on conviction as well as a hefty fine. In fact, this instruction was probably written in a country that does not have type AC RCDs available, and the boiler does not require anything any fancier than the minimum. Let's assume a TT installation. There is NO additional protection available except bonding or perhaps a number of RCDs in series. Most important there is no danger, so just what do they mean, and certainly no explanation of why a type AC is needed!


    Aligarjon, British gas should lose its electrical certification. This is again just plain wrong. It appears that very few persons understand RCDs, DC Current, or anything else.
