Random RCD tripping
In message
From: a ) Subject: Random RCD tripping Would I be right in thinking the only culprits (appliance wise) are those that have an earth connection - so I can disregard all double insulated apps (which I think is most of them except kitchen apps)? well, the earthed ones are far more likely culprits, thought its not quite a 100% thing. Nearly though. Prime suspects are always things with water heating elemtns in: washing machine, dishwasher, kettle, oven as well, and the biggest cause of all is immersion heater. Alternatively, insulation test or pat test all appliances, including the fixed ones. Of course it'll cost you. Hmmm, last resort... Why not test everything with a multimeter first? No guarantee it'll pick out the duff appliance(s), but it usually will, and its cheap and easy. Check resistance on max R range between earth and (L&N connected together). Suspect the item(s) with the lowest insulation resistance reading. Note: make sure the switch on the appliance is on, and item set to boil, otherwise you'll only be testing a part of the appliance. Obviously I dont maen it should be plugged in during test NT |
