Ever since the new central heating system was installed,,
I cannot place a light bulb into the upstairs hall light,,
it tripps the tripper,
the installation was (of course) carried out during daylight hours no one checked what happened when you put the upstairs hall light on ..
..
I missed the bottom step the other night,,
fortunately I was abit rubbery at the time..
..
How much hassle to fix..
??
Call CH installer, explain problem, get em to look/fix. Maybe they will.

Oh well thanks for your reply..
I did not notice the fault for months..
Wee ( my mother and I) were going through a period of enforced good intentions at the time from local services.. I think,, leads to family//
We now have a shower and bendy down support so tha she can get to get on tha loo..
Its never been used once
Never used once by my mother,,
He mobility was plumiting at the same time as enforcement of shower she did not want..
I bought an electric chair to lower her into the bath,,
It was never ever used once,, i gave it away to charity after the bath had gone.
She was very distressed listening to the plumbers breaking up her bath..
She was so aware of her things being broken and destroyed..
Today she has some very good carers that could easily supervise her having a good ol soak inna nice warm warm bath... With the electric chair that we no longer have..
I have been on a journey of discovery.. of late.

Th plumber boy was a football player for annan,,
and his employer was from lockerbie..
Ok ill try the quierie iff i can find there number
it was a while ago now..
////
MCB or RCD?
My first guess would be the CH fitter has put a neutral in the wrong bus-bar in the CU or borrowed a neutral from somewhere he should not have.

Are you suggesting there might be an easy wiring fix..
plummers do plumming ,,
leckytrician came in too
..
I understand that there is something abpout three way wiring for two way switches..
I thought maybe it was an earth problem..
..
Ive
Forgotten what little i knew about that simple circuit
..
Is there an easy fix possible,,
..
Mike
My guess is RCD,,
could be wrong thoug..
I never heard of MCB,,
How do I check
which
??
Does the trip that opens have a "Test" or "T" button on it or not? If it does it's an RCD (or MCBO), if not then it's an MCB.
It helps not to get your abbreviations muddled, I meant to type RCBO!
I hate abbreviation;s also..
Will take your remarks under consideration ..
tomorrow..
If i put a bulb in the upstairs hall and switch it on
the whole lot goes off..
I thought an earth leak was the cause,, three way rcd..
But what do i know ,,
ill get back tomorrow
thanks//

It's common (although it was always wrong) for the landing light, which is switched from both downstairs and upstairs, to take the live from one lighting circuit and return the neutral to the other. That never works when RCD's get fitted.
Are you sure this doesn't coincide with installation of RCD's in the fuse box? Maybe that was done same time as boiler installed?
If so, you might temporarily get away with a very low power bulb, such as a 3W LED, but there's no guarantee even this will work, and it needs to be fixed properly.
Earth fault would be a possibility.
If the house has what is called a spit load consumer unit (i.e. its divided into sections where some are controlled directly by the main switch and others by a RCD), then a "borrowed" or misplaced neutral would be another possibility.
Three way? Note sure I follow.
Either way, since its a nice easy to reproduce fault, it will be fairly quick and easy to find if you are up for a bit of diagnostics...
It is a fairly easy fix, but it needs enough skill to see where its miswired.

Is that an offer to assist?

One possibility since you mention a new central hearing system is the insta ller has inadvertently damaged a cable between the light switch and the lam p in question, maybe the cable is touching a hot pipe or now has a nail thr ough it. Another is that he/she has moved a wire serving some of the lighti ng within what may be a split load consumer unit to take over a circuit bre aker to serve the new heating system (it happens) and has not moved the ass ociated neutral wire. There are endless possibilities but you don't sound f amiliar enough with electrical systems to be poking about inside the consum er unit, therefore you should get him or his electrician back.
But if that were so, it would affect every other light fitting on that circuit too. I can't think of a rational explanation other than coincidence. Really need more info. Does it trip when the ligh is turned on? Is it the RCD trips or an MCB? Does it trip at the moment of insertion?
I cannot quite see how fitting central heating can do this. Even if there was a shorted cable, ie screw through it I'd expect it to happen if there was a bulb or not
You don't say if its part of a 2 way wired system with the downstairs, but even if it is, it still seems to be a rather strange fault to have. Nothing so simple as a bit of bare wire insidt the lamp socket I suppose? Brian
unless the screw hit the switched live?
Did the plumber change the fuse box or any parts in it?
Is this a pendent light or one mounted flush to the ceiling? Brian
Just a ramble: I think "Plumbers" are often (if Watchdog is to be believed) used to do many tasks that they have not been trained to do and may not have the aptitude for. Jobs like Tiling, Electrical Work, Boiler Controls are really outside the scope of a "pipe strangler"
Obviously some can do it and make a good job - but we should probe "Plumbers" before letting them loose on our homes to ensure they have credibility in all the aspects of the job they are being asked to do. Surely it is better for them to sub-contract some stuff (from what I seen)
Well ok,,
I dont know that it is miswired,
There is a new thirty milliamp breaker wired to an old fashioned fuse box, in a house that has never been rewired.. forty years,, at least,,
I am looking suspiciously at the old braided wire hanging from a rather "high" hall ceiling..
My feeling is that breaker will be ok, that will probably be wired ok that it is doing its job as it is designed to do. and that it is quite correctly detecting an earth leakage in some old wiring ,
I do not put a bulb into the upstairs hall light because it trips the breaker,, it does not say RCD but I assume that, that is what it is,, and rcd..
The installation of central heating caused a great deal of disturbance around the house..
Also, I have to correct myself,,
I think the rcd was installed subsequent to having a wet floor shower and fan, the shower is heated from the boiler..
..
My guess is that fault must lie somewhere in this circuit
How to convert one way lighting circuit to two way switching Diagram No.2
..........
did they use the bare earth wire as the third wire required for two way switching forty odd years ago..
My view is that it will be a hassle to fix if (as I suspect) it will need a new wire between the light switches..
The tripper trips when I switch the upstairs light on,,
Ok i should check the light fittings, but it is a such a dam awkward spot, I just took the bulb out,,
Dark nights are hear again and it is getting to be a nuisance..
Hope I have covered all the queries,,
..
if there is any chance the rcd has been wired wrong..
well Im listening,,
//
PS there is a paper tab on top of the rcd that says ,,,lights and toilet fan,,,
...
The fuse box has fuses for upstairs lights and downstairs lights,,,
I assume that the upstairs hall light is connected to the downstairs light circuit.. now there is a thought for an easy fix,,
// I expect that the old wiring is set in plaster as it runs down to the switches//
