Tripping RCD after smart meter install

Stewart Mason
I got called to a property today. The RCD had started tripping after a smart meter was installed. The insulation resistance between line and cpc was over 300 Mohm on all circuits. The RCD was an MEM unit in a memera 2000 consumer unit.


Whilst at the property the RCD did not trip. I did a google search and one result suggested the RF from the smart meters transceiver was upsetting the RCD. When the smart meter was first energised I guess it starts communicating with the supplier causing said RF.


We have had 3 properties now all with MEM RCD's which have started tripping after smart meters have been installed, normally in the early hours of the day.


Just wondering if anyone else has experienced of this issue?

    ...you need to think not in terms of the Euronorm standards, but more like DefStan or MilStd, depending if you prefer MOD or NATO.




    That is all very well but are the standards readily accessible?  I wanted quote DefStan 59-411 (Marine EMC requirements) in a specification and when I asked if I could was told it was restricted and could not be made available. I pointed out that is was readily accessible on the internet to anyone, though did not receive a response to this. However, a week later when I tried to get it from the internet.......... Gone! (I should have just kept quiet - and also saved a copy)
