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?

    The smart meters use two communication systems to send their data back and the system chosen depends on where you are in the country.  Some use the Arqiva network (North of country)  and will work in the 900 ISM band at 868 MHz while others are on the O2 network. (South and central regions)    Most likely in the 900 band which is 900 (UL: 880-915).
