markc Posted January 17, 2008 Share Posted January 17, 2008 I have a very annoying intermitant problem with our house electrics. The RCD on the main fuse box keeps tripping. This happened mainly in the early morning 5ish but is now tripping during the day as well. How can I find out what is tripping it - Are there any electricians local (hampton court) that would like some work ? Regards MarkC Link to comment Share on other sites More sharing options...
Johnty Lyons Posted January 17, 2008 Share Posted January 17, 2008 Early morning Fridge is opened and closed a lot so compressor cuts in suggest Kitchen cct even if its not fridge/freezer. check out your oldest electrical appliance. jj N.I.

Johnty Lyons Posted January 17, 2008 Share Posted January 17, 2008 Just noticed you said 5ish What time is your heating programmed to come on???? jj N.I. L7C AR 🙆🏻 Membership No.3927. Link to comment Share on other sites More sharing options...
markc Posted January 17, 2008 Author Share Posted January 17, 2008 Im not up that early opening the fridge Heating comes up 6:45 so ruled that out have turned all outside lights and water features off - its happened during the day. Had thought it could be the ups on the server ?? - but never seen this before and i've installed a few in my time 😬 thanks MarkC Link to comment Share on other sites More sharing options...
Gridgway Posted January 17, 2008 Share Posted January 17, 2008 Mark, if you need an electrician, the one we use is good. Graham Link to comment Share on other sites More sharing options...
Sheds Moderator Posted January 17, 2008 Share Posted January 17, 2008 I would isolate 1 circuit at a time and see if it still happens. Caveat - this means the heating may not come on if you isolate it... I used to have a fault where the burglar alarm would false trip. Turned out it was the CH which had a fault at shutdown - it turned the pump on and off afew times and generated spikes that tripped the alarm. You could have something similar in your house.

Johnty Lyons Posted January 18, 2008 Share Posted January 18, 2008 I reckon its a motor cct somewhere so you should be able to isolate it. jj N.I. L7C AR 🙆🏻 Membership No.3927. Link to comment Share on other sites More sharing options...
markc Posted January 18, 2008 Author Share Posted January 18, 2008 Thanks Graham - can you let me have the details - ta Will see what happens - changed the RCD yesterday to see if the old RCD (14yrs) was getting weak! Regards MarkC Link to comment Share on other sites More sharing options...
Foggy Posted January 18, 2008 Share Posted January 18, 2008 Mark, This is a long shot but I have just had a similar problem which occurred at about 5pm! After isolating the respective circuits I discovered the reason accidentally. ..... condensation from the microwave was running down the kitchen tiles and into the socket!!! Now I'm not suggesting this is your problem but it's something I hadn't considered myself, however, given the time of year is it feasible in your house as well? Just a thought Link to comment Share on other sites More sharing options...
markc Posted January 18, 2008 Author Share Posted January 18, 2008 Foggy Thanks for that - I had thought about condensation - went round and made sure all the outside sockets were shut properly - a couple were not. As I said - changed the rcd and its holding up - but we did have the lights flickering a short while ago - this would probably of tripped the rcd. Now why would the lights flicker ??? - didnt shut the machines down tho. MarkC Link to comment Share on other sites More sharing options...
martin b Posted January 18, 2008 Share Posted January 18, 2008 Mark Is your consumer unit a split load or are all circuits protected by the rcd, normally lighting is not, which is why it wouldn't have tripped, its really just a question of identifying a circuit, then isolate the appliance on that circuit. A real pain when its intermittent 🙆🏻 Martin Link to comment Share on other sites More sharing options...
andy_h Posted January 18, 2008 Share Posted January 18, 2008 May not even be your problem. Could be a fault on the cable coming into your house which can appear to be your cable fault. If you've done the checks your side advise the Elec board to see if they want to investigate as they may have a cable below ground which is about to fail (being squashed and intermittant due to temp change/amount it gets squashed).

Gridgway Posted January 18, 2008 Share Posted January 18, 2008 Mark, the man you need is "Jimmy" who is J&D Electrical on 07958 328271. He has done quite a lot of our electrics including garage power that came and went sporadically. Graham Link to comment Share on other sites More sharing options...
JampJ Posted January 18, 2008 Share Posted January 18, 2008 Probably just a weak RCD, our lights flicker on a regular basis early morning, we've been told it's due to the local schools generator starting up.

markc Posted January 19, 2008 Author Share Posted January 19, 2008 Graham - thanks J&J - I have changed the RCD for a new one which is slightly higher in ampage ?? (if thats right) Since doing so - we have noticed the lights flicker with no tripping - so now all I've got to do is find out why the lights flicker 😬 Had a sparky in on Friday and he said to put RCD on all power - in the fuse box - at £50 ish a go - with 6 fuses thats a fair whack - so will use that idea as a last resort. Thanks to all MarkC Link to comment Share on other sites More sharing options...
JampJ Posted January 19, 2008 Share Posted January 19, 2008 Ours and various other houses in the same road all have the same problem, someone checked with the lecy board and was told it was probably due to the local schools generators starting up. They are sill investigating! Cheers John JFDI (Just F*****g Do It) Link to comment Share on other sites More sharing options...
