Plumbers. Bless them.

No John, it's the only issue. Can the green and yellow be over-sleeved or not ? NIC say yes for heating controls.
If you don't care whether the installation is compliant with the current wiring regs, then maybe it's the only issue for you. As you know, I agree with you that the regs probably do allow oversleeving of the G/Y, even if it is an 'orrible practice - but if the cable without a CPC is considered non-compliant, then it is non-compliant regardless of considerations of core colours/identification.

Then what will you use for the cpc?

Why do you give such credence to the NICEIC?
They are well known for inventing their own rules.

Hey what do I know.

Who would You, recommend and I'll ask them as well.

John, one should assume if it didn't comply with something they would have said no, or is that plumbers think.

Us ? How many have said 'No'?

As John has said, even if you can find no regulation which specifically prohibits it, it is not possible to do it and comply with other specific regulations.

Many people are very narrow/'focussed' in their thinking, and address only the question they have been asked. If you ask them only about oversleeving the G/Y, they may therefore fail to even think about the fact that this implies you are going to have no core left to use as a CPC. Hence, if you actually want to know whether the totality of the situation (oversleeved G/Y and no CPC) is regarded as compliant with the regs, then you really need to ask about both issues.

John the inspector visits the site and say signs off 500 houses.

I'm a plumber/heating guy, what do I know about BS 7671:2008 amd 1 2011 ?

As far as I'm concerned the inspector knows his job, or he's taken the word of the spark onsite.

Mind you the last job I was on in London the sparks couldn't even speak English, let alone read the regs. :LOL:

I meant how many here have said no.

Anyone you want me to ask.
No, I can read and am quite satisfied with the conclusion on the forum.

Care to pen the question and I'll copy and paste it.
There would be no point.
There are so many contradictions in the OSG and Approved Documents, presumably written by 'someone else', I will stick to reading the BGB, not that that is flawless but it is 'The Regulations'.

You're talking about two rather different issues - (a) whether or not the practice you're describing is compliant with BS7671, and (b) the fact that one particular inspector is happy to sign off the work which involves this practice. Although, in an ideal world, they should be the same issue, in the real world that aint necessarily so!

It is unrealistic to expect a sparky or a plumber to rewire the heating controls in old houses.
It is also unprofessional, and immoral, to expect any tradesman with any self respect or sense of professionalism to re-use or reconnect same.


Its just not going to happen.
Not for as long as ignorant clowns like knows****all are around.


Its rare to se bare earth as a live conductor - but with boilers needing pump over run - it does sometimes happen.
There's not even a "should" here - that MUST never happen, and if found MUST be replaced or disconnected.


Do u sparkies ever consider pinched neutrals on the heating ccts when upgrading to R17? If u wire it in the summer with the S/Y plan off - u wont know there's a problem till the heating comes on & both RCD's trip!
Spoken like a true plumber who knows SFA about testing, and cares even less.
 
hello BAs Justgot back from you favorite doggy spot.

Want to post some Regs so you can educate the plumbers :LOL:
 
I agree - that pragmatic approach is probably the best one can hope for (for existing installations).
Actually no - the best one can hope for, and the least one can expect from a professional is that it gets sorted, and that the "opinions" (if such intellect-free dribblings can be termed such) of t**ts like cares****all are ignored.


If one is dealing with pre-existing, buried, 3-core cable, then I can see that some people might think that ripping out and replacing the cable was rather too much of a hassle.
I'm sure they do. All sorts of lazy, incompetent, DGAS people think all sorts of proper behaviour is too much of a hassle.
