[QUOTE="Robin Spark, post: 212179, member: 5444"] Hi Soulman, could it have been possible that your earth test lead wasnt plugged into your tester properly? I had a situation recently when after changing a consumer unit and finally putting my socket adaptor lead set into my tester I didnt notice I had put the blue lead into the earth connection on the mft and vice versa with the green lead. When I tried to check Zs at downstairs sockets it tripped the rcd every time. I got really frustrated when I checked sockets on the upstairs ring and the other rcd tripped the same. sometimes the problems are so simple and right in front of you, but when something happens unexpectedly it can get you all in a fluster!!!! This is the time to take a step back and a breather and look at the situation starting with all of the basics. PS have you checked Zs on any other circuits to ensure integrity of the earthing system?
