UK New timed fan isolator and switch... but lighting circuit is via

[UNG]

Well, the Quickwire was already in place and I've yet to see the logic of ripping out one system to incorporate another that ostensibly does the same thing. Unnecessary work in my opinion. Still, all done (and with that diagram, took me less than fifteen minutes to do the whole thing). Happy days...

It didn't take you less than 15 minutes or doesn't all the time spent looking or a workable solution count in the job time

Fair point ... but if people actually answered the original question - what is the solution - instead of petty carping, sarcasm and in some cases, ideas that would never pass a Part P inspection (all of which suggests they didn't know either) - yes it would have been done a few days ago.

You were given various options here, some of which the manufacturers have confirmed did not make reasonable provision in the design and installation of electrical installations in order to protect persons operating, maintaining or altering the installations from fire or injury?



"Signed off" by who?



"Approved" by who? Under what approval regime?


Sorry, Christo, but we seem to be going down a rabbit hole of misconceptions and old wives tales here....

Signed off by the IET. To standards BS EN6070-22 and BS 5733-MF.

Let's assume that compliance with BS 7671 has been chosen as the way to comply with Part P.

So any "Part P inspection" would be to determine if the work complied with BS 7671.

What suggested solutions have there been which don't comply with the wiring regulations?

I'm not aware of any process to have designs signed off by the IET, nor that they run a standards compliance test house.

BS EN 60670-22 is the standard for boxes and enclosures for electrical accessories for household and similar fixed electrical installations.

BS 5733 covers general requirements for electrical accessories, and the MF logo was introduced in it as a marking that can be used on accessories to indicate that the accessory doesn't require further inspection, testing or maintenance after installation.

Where has a solution been suggested which does not use items complying with the appropriate standards?

Well, one was to take the isolator out of the loop altogether so it isn't an issue, another was to connect the line to the switch live... Maybe those are acceptable solutions in some instances and not in others. Fair point.

Anyway, it is all done. Tools away happy days.... Sun is shining, and today Mr Drakeford finally allowed pub gardens to reopen, so I'm off for a brewski. Could life get any better...

Thanks for everyone's suggestions, and I hope that diagram is of use to others in a similar predicament. Nobody suggested the same solution as per the diagram, good thing it wasn't an exam question eh lol

And your point is what exactly, I doubt an exam would have a question about using over priced junction boxes

To clarify and address some of the misconceptions I would counter that none of the solutions offered in this post by myself or others would fail any inspection. The day exams start having questions on specific branded products is the day I hang up my screwdriver.

As posted earlier the Quickwire diagram is electrically identical to other solutions posted, it just uses their product. (Twin and Earth with 1 core unused is the same as single core and Earth!)
At the end of the day you needed a switched live from somewhere and whether it comes from the fitting itself or via an extra Quickwire box or enclosed wago or any other maintenance free junction box is irrelevant to any inspection as long as it’s installed correctly. I could probably solve this a different way each day of the week and meet wiring regulations each time.
Any rate, I’m glad you got it sorted.

I appreciate that but you're missing the point. It isn't the brand that was the problem, In any other scenario I could quite easily have gone for WAGO or another brand, even an old school junction box (well, actually not. The first problem was (and still is) the location.

All the wiring for the bathroom runs under the floor - not floorboards, floor. And is concreted in in some places, plastered behind six inches of plaster in others. The only bare bits are the ends where there would have been a junction box or a switch the junction box (or ceiling rose, nothing would surprise me) for the bathroom. Whoever came in was presumably told by the then owner they couldn't afford a full rewire so did the best they could in the limited space and limited budget. And went for Quickwire.

Quickwire - and there are others on the market - connect all three wires into their system. Their USP is you don't need to sleeve any cabling, as the gubbins inside does all the wiring. Given the location, previous electrician opted for Quickwire. Which does the job perfectly. As long as the fan doesn't need a timer overrun.new homeowner moved in, wanted the forty year old extractor that has a pull cord on/off ripped out, and a new one with a timer overrun. Didn't even know about the wiring or Quickwire, because they only bought the house recently.

Most of the answers ignored the location issue and offered the usual lazy suggestions - use another brand, chop it up, argue with the homeowner. Which clearly showed they didn't read the original question properly. And what you say about branding is nonsense if you're out on a customers property. You are somewhat governed by what is already in place, what the customer wants and what is practical (and compliant) for that location and installation.

Finally a short sharp word with some of the tradespeople on here, you don't dictatcte to customers what they want. They tell you. If you're a car mechanic and a customer turns up with a Ford that has a faulty clutch, you won't stay long in business if your response is to sniff, and say "well, shouldn't have bought a ford then", or "I can jam in one off a Peugeot see how that works...". If you heard a car mechanic talk like that, you'd take your business elsewhere. They're clearly not as good at their job as they think they are.

Thanks for your reply. I agree I was missing your point though it is now becoming slightly clearer.
I think my confusion was that until the last post you just said "Part P location" and to me that isn't hugely prescriptive term as it applies to a lot of situations. @Soi disant made this point earlier.
I think throughout this thread there has been a misunderstanding about the use of that term, what several of us believed it to mean, and what you intended it to additionally convey?
Also agree that QW are an excellent solution to scenario's where there is difficult and limited access.
Anyway, certainly not trying to start a fight! Apologies for the confusion.

You are clearly a TROLL and are IMO deliberately trying to provoke an unnecessary response from the members on here with your original question and responses. TBH when you started this thread it sounded like a quickwire employee trying to advertise the product rather than someone trying to solve a problem
