I have a strange RCD tripping problem, we have a dual RCD consumer unit, when the main switch is turned off both RCD s activate, they have activated individually but not at the same time. There is no continuity between the neutrals and both sides have an insulation resistance of >25 meg, we have replaced both Rcds which are now Schneider , yet the problem still persists, everything tests fine. So I'm either missing something obvious or not, any help would be gratefully received, thanks
