Oh. Just seen your reply. Glad you've solved it. :-)

Have you solved your problem yet? Well, anyway, I am no electrician either, but as you sound desperate I'll give you my 2 cents' worth. In short, I reckon that there must be some kind of shorting-out occurring INSIDE the consumer unit, perhaps by a bared wire that runs passed many...

OK, thanks for that. :-) Please can you explain what you mean by horror and _why_ they are a horror? Thanks.

Oh well. What does C&N mean? Yes it is! :-) Well, thank you for that question. I do have sockets on one circuit (kitchen ring main with freezer on it.) Also, my garage power (lights and sockets) are on another RCBO. The other 3 RCBOs are all lighting circuits. What does Type C...

Of course I didn't put the RCBOs in the RCD side, I put them on the unprotected side. ;-) Anyway, what I'm after is answers/comments on my original _questions_ if anyone has any. Thanks :-)

Oh, I wanted ALL circuits to be RCD protected (overcautious of me perhaps) AND I did not want a fault on one circuit (e.g. garage power) to bring down another circuit (e.g. a lighting circuit or my kitchen ring-main (fridge-freezer)) So, the one big RCD was not enough for me. That's...

Hi I have recently installed and wired up my 12-way split-load Volex Consumer Unit in, my house, inserting 5 RCBOs and 5 MCBs (plus a door-bell transformer (2 slots.)) It all works fine but boy did it take ages to get the wiring tidy enough so that I could fit in those damn tall...

My pleasure. Yes, I pondered over this too. I cannot really add much here but the potential on LIVE wire _is_ continually changing (sinusoidally) and so this must count for something. Quite how I am not sure. Perhaps it is purely an electric field effect and not magnetic??? No, I'm...

Hi Thanks Kendor for your input. To [hopefully] conclude this matter, I did the following experiment which I believe adequately explains my 91V issue and the energy saving light. I took 3 metres of 1mm^2 twin and earth switch cable, and lay it on my floor. I then connected on one end...

Hi (Yes I am using a really decent digital meter with a very high resistance and that it *seeing* things (voltages) that aren't really an issue.) Anyway, at long last I got this answer from another source and I think it is correct. Capacitive coupling is highly likely to be the problem...

Hi I have tunred off ALL circuits except the upstairs lighting circuit and the 91V remains there. The only way to get rid of it is to turn off the upstairs lighting circuit.

Hi I did some more measurements tonight and I believe I have solved my probelm. The values I reported earlier were not quite right - I remembered wrongly. So, at the ceiling rose, the voltages are: Between LIVE and NEUTRAL = 240V Between LIVE and EARTH = 239V Between EARTH...

The 6A RCBO is rated to trip at 30mA, and indeed it trips when I press its test button. The RCBO, I thought, only trips if the _current_ in the neutral differs from that in the live, rather than being voltage orientated. I will recheck all the voltage readings tonight to make sure they are...

OK, will do checking tonight. So, are you convinced there is a fault? I should have said that I am using a _digital_ multimeter, so that will be very sensitive to any voltages around. There cannot be much of an issue though because the tungsten light could not draw enough current to...

So there is some sort a *floating*? voltage on the neutral wire. Everything seems normal to me voltage-wise, but this 91V I am unsure about, is it normal or not? Tricia --

Hi I have rewired my whole house (lights and power) and it all seems to works fine and has been for a few months now. I would say I was competant at this job but I am not an electrician. Last night I noticed that my Philips energy saving light bulb on the stairwell light ( on the...
