[QUOTE="deeley_s, post: 391853, member: 26188"] Hi Folks, Thanks for all the good advice in here. My first thought was pond or Mice (we did have some, but got rid of them) or perhaps condensation from a damp problem. But the fact is that while some of the trips are completely random, others are closely associated with turning on an appliance. This morning the trip went twice when I turned the kettle on. This evening I plugged the same kettle into the same socket - and it was fine. I can't square that with a pond pump (which has a fast trip RCD on its own CU) or mice nibbling cables. But I think Binky and Kerching have a point. I think we possibly have so much normal leakage that we're close to the limit on the RCD and the next appliance we switch on, whatever it is, is enough to blow the RCD. And the MCB? I'm thinking inrush current when everything starts to switch back on again at the same time. I then go around yanking plugs out, and lo and behold the MCB and RCD both switch back in without a murmur. To be sure, I need a sparky in North Wilts who can run a megger on the cables and if they have an earth leakage meter, so much the better. Any recommendations? [/QUOTE]
