Random RCD tripping
I changed our old fuse box for a split load CU a few months back. We were
having a problem with the RCD tripping which I put down to a faulty iron - replacing the iron seemed to cure the problem. However in the last week or so we have had 3 trips at random times, both while the house was occupied and unoccupied. Anyone have any tips on tracking down the problem? The RCD currently covers 3 ring mains - upstairs/downstairs/kitchen - I guess one option is to transfer a couple of rings to the unprotected side and see if the trips carry on, and if so keep swapping them until they stop, which would isolate the problem circuit but still not the precise problem. cheers Dave. |

I had this recently as well. I unpolugged tow mains extesnions that were on teh outside sockets i teh rain and it stopped.. An earth neutral short, or bad earth neutral leak can cause unpredictable tripping as loads come on and off. If you have teh patience, switch everything off n te CU, and disconnecrt reahs one by ne and se if any show continuity to tehneutral busbar. cheers Dave. |

This is the price tag for installing one RCD on all your rings. Next time you'll know better. The best approach is to put RCBOs on the rings, and change the RCD isolator switch for a switch only. Whichever ring trips, ensure the freezer isnt on it. There had to be a good reason for spending the extra on RCBOs - doh! The fridge/freezer is not on the RCD side fortunately ;o) Now with 3 trips it is relatively easy to locate the dud appliance(s) with no further cost, simply by moving them between rings. Divide and conquer, move half at a time to narrow things down quickest. The problem being the trips are random, and might not happen for several days. It isnt easy to move stuff around and leave them there for days on end! At the time of tripping these are the likely things plugged in (but not necessarily in use, probably on standby if available)... Upstairs -------- hi-fi Phone Charger tv multi skt extension - video/dvd/pc/lcd monitor/printer/camera charger alarm clock lamp Down ---- lamp tv multi skt extension - video/tivo/digibox/dvd Kitchen ------- microwave kettle gas oven washing machine 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)? Alternatively, insulation test or pat test all appliances, including the fixed ones. Of course it'll cost you. NT Hmmm, last resort... |
