Smart meter tripping RCD anymore than anecdotal evidence?

Sparkingchip

With have heard reports of smart meters tripping RCDs, is there any more than anecdotal evidence?

    Around 11 mA background leakage measured on on the meter tails, which is now spread across half a dozen 30 mA RCBOs, so negligible.

    The new RCBO for that circuit trips at 27 mA, however I fitted a 300 mA upfront RCD because it’s TT which trips at 210 mA and it has taken that out as well.

    So I have ordered a 100 amp 100 mA time delayed RCD which is advertised as a Type A which is something I not seen as yet, up until now I have only ever seen Type AC, if it is what it is said to be I will swap it out for 300 mA to solve the lack of discrimination issue.

    I know this is going to turn out to be something really simple, but at half five yesterday evening when I was getting an insulation test result of 1.8 Giga ohms there didn’t seem much point in carrying on stripping the circuit.

    The next step will probably be to swap the upfront RCD, test the circuit again and if I get a high insulation value again split the circuit onto two RCBOs to see which half of the circuit trips rather than dismantle the circuit without knowing what I am looking for.

    Hardly the most scientific method of testing, but hey ho when needs must.
