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?

    There have been reports of RCDs being tripped by 'walkie-talkie' type hand-held radios - so RF interference does sound plausible.


    I gather most smart meters use the mobile phone network to communicate with the outside - so perhaps an experiment with a mobile phone (sending a SMS perhaps) close too the RCCB might be worth a try?
