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

    This is what I asked:

    Thank you. I fear that there has been a misunderstanding. The boiler is powered by the normal 230 V AC domestic supply.

     

    The boiler manufacturer says, "The correct type of RCD must be employed where additional

    protection is required that is suitable for a low energy DC modulating pump according to IET wiring regulations."

     

    I am aware that some type AC RCDs are incompatible with some electronic devices. Is yours compatible with such electronics or not please?


    This is the reply:


    Thank you for the enquiry effectively you are looking for an A Type RCD which features the characteristics of a smooth DC fault current is less than 6 mA, as the standard RCDs we offer in this range as all AC type and dont have this feature,


    However We now offer a 63A Type A Easy9 device if this will suit what you need for your application product part EZ9R46263 - EASY9 RCCB 2P 63A 30MA A TYPE 230V

    I still don't know whether the existing type AC RCD would be tripped by this boiler, but I think that it would be wise to change it for a type A. It would be a bore to find that it does when the system is commissioned.
