Hello Guys


I'm going to put my Tin hat on and close the curtains so the Regs police can't arrest me for asking this question again, I can only find old threads pre 18th edition so please advise me if I'm missing something


I've just been watching a guy on Youtube doing a board change who's said that to comply with the 18th edition of the Wiring Regulations you must seal ALL entry holes into a consumer unit regardless of them coming through the bottom, top, sides or rear entry with a suitable intumescent mastic to stop the spread of fire into the fabrication of the building!!!


I personally am NOT aware that anything changed in the 18th Edition to say all entry points have to be fire sealed I've been looking online tonight and can only find write ups from "Wiring Matters"

Stating


Sealing of wiring entries
It is important for the installer to seal all openings into the enclosure or cabinet for cables, conduits, trunking or ducting that remain after the installation of cables - see Figure 6. The intent of the sealing is to ensure that, as far as is reasonably practicable, any fire is contained within the enclosure or cabinet and the escape of flames to the surroundings of the cabinet or enclosure or into conduits trunking or ducting is minimised, as intended by Regulation 421.1.201.
Good workmanship and proper materials must be used, and account must be taken of the manufacturer’s relevant instructions, if any.


Regulation 421.1.201 Does not mention sealing any apertures in a consumer unit with, grommets, glands or sealant and does not mention that the Metal clad board cannot be fitted to a timber backboard. So why is the IET saying we are to be sealing the holes , personally I've been installing all my boards with cables entering from behind and mounting my boards on the existing wooden backboards using a length of stick on trunking as a framework around the consumer unit.


Am I wrong???

Body swerve and cop out eh?! I see no reason that you can’t put your response on here for the forum members to read?

I did try calling but after 437 guesses at your number I had to give up :( However I’m not really that keen on talking to sassanachs ;)

No I will answer in due course that’s not a problem just wanted to talk to you personally as your comment was aimed personally at me and not the issue of fire sealing a consumer unit.

@DPG Think he wants a date o_O That or some proper training :)

Cant see why he can't answer the questions.

He called us all a bunch of old women, thats personal comment on everyone. Perhaps every member of the forum should ring him

Was this fire started by an electrical fault?

The point is that while the installer may feel like they are going above and beyond the requirements and making it safer than the minimum standards they are likely achieving absolutely nothing other than wasting time and materials. Also they often make the issue worse by misrepresenting their efforts as a requirement or a safety improvement they are neither.

This leads to problems down the line as people have an annoying habit of believing hearsay and gossip over things written in black and white in the regulations. Just look at the number rof things which get picked up on EICRs which are non-issues.

The fire in the control board was caused by a poor connection. The fire at my Aunt's was caused by a faulty appliance.

I don't disagree with you! there is nothing worse than someone stating something is a requirement when this is not so.

I do what I do for my own peace of mind, whether its a waste of time or not does not concern me because if it helps me sleep at night then its worth the effort.
For example my partner goes around the house and switches all the sockets off and unplugs everything that can be. Its probably over kill but it gives her peace of mind.

Ahhh your in Englandshire explains a lot.

Touche!

Can't answer some simple questions, has various videos showing non compliant work and doesn't like it when it's pointed out. Undertaking unnecessary work (and no doubt billing the customer). Childish comments vis vis 'bunch of old women' and now a dumb attempt at a veiled racist joke...

I think I have your measure :p

And to save you the bother - yes i wear a skirt, no I don't wear pants, yes I have a beard, yes I'm ginger (collar and cuffs), yes I eat intestines, yes I shag sheep (but not my own as that would be incest). Yes I like a pint of heavy and a dram of the uisge bertha. Yes I fancy the 'Sturge' (even if she looks like wee Jimmy Crankie) and yes I believe in independence.

Over to you now, lets hear your worst Chris...

I'm really sorry to read your experiences. Thats awful. I dont think what you and your partner do is overkill. If it makes you feel safer then thats only a positive thing.

Hi Richard
I’m quite upset that you feel I was being racist in anyway. I was only pointing out the fact your in Scotland and work being quite thin on the ground there. You might have to much time on your hands to sit at your computer or iPhone screen trolling the internet to try and make others feel bad to in return make yourself feel big and better. I’m sorry you are ginger that can’t be helped unfortunately but I can recommend a good hair dye.
Going back to your original question regarding my competency I will definitely give you a detailed answer later on today when I’m not so busy doing unnecessary work and over charging my clients for it. Speak soon x

Okay Richy and Chris enough is enough this has totally side tracked the thread and turned into a baiting match. I have deleted one post so either reply with regard to the OPs question or don't post at all.

Reading the last couple of posts it's starting to put the forum in a bad light.

I have taken a look at the video that was posted there was a big hole behind the existing consumer unit.
Now I have not fitted many Hager consumer units but it looks like there is knockouts on the back that knock out as a whole, not in parts so there is more aperture that is needed the only thing that can be done is make good the wall or seal the hole. How much is a tube of intermittent mastic?
