Hello Guys, It's been a long time since I posted anything here, but I'm puzzled by this. Kitchen refurb, extended existing ring circuit. Integrated dishwasher installed, isolated by a switched connection unit above work top with cable outlet down below. When the spur is switched on, the 80 Amp, 30mAmp, R.C.D in a split load board sometimes trips. Tested insulation values on machine line to earth, neutral to earth, line to neutral, all way above 200 Megohms (when machine button is in off position) Tested circuitry, ring complete, insulation values again well over 200 Megohms. Tested R.C.D 1/2 no trip, X1 29Msec, X5 19Msec. BUT, if the spur switched on, then the R.C.D is reset, it don't trip. Any ideas? Thanks
Why do batteries run out of electricity? Why does a light go out when you switch it off? Why does a cup of tea go cold after 1 hr? Why is your plate empty after eating the food on it? Why do cows go moooooo?
