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 would need to create an account on  the UK defence gateway to access the "Dstan"  documents officially .

    For obvious reasons if you answer 'no' to the 'do you work for the MOD' questions you get a civilian access only.

    Then certain standards are kept from you, mostly the ones about munitions, and some other hot topics that might be useful to enemies.

    However, all the basics, like EMC stuff, and the mechanical transport (shake rattle and roll...) and the environmental tests are available to everyone, free issue, or were when I last looked late last year, mainly so that when tendering for MOD contracts, companies know what standards to manufacture to.

    They don't hand out registration willy nilly, but any person or company that is potentiually part of the MOD procuremnet chain, and so needs the access so thay can make, sell or test components, would normally get in.

    There are plenty of older copies of many of the Defstan docs out on the web, but it is all crown copyright, so respect that. Note that  '511 is mostly EMC for general, thought some sections may also apply to marine.
