In my youth I was cleaning the bathroom extractor fan at the girl friend's parent's house when ever helpful mum put the light on so I could see better.
Is a cooker isolator required? *POLL*

Did it not occur to you that in the last two months I've had a new boiler installed and the plumber put it on a different circuit?
Why would a plumber go to the trouble and expense of the electrical alteration of putting your boiler onto a different circuit ?
Go on Winston..... tell us the reason.....please
I don't follow. What is that regulation?
Ok. Not very - what's the word - conclusive?
No it doesn't. If the manufacturer is demanding something which is not required by the regulations, then that something is not required.
Examples jump to mind - 3A fuse for extractors regardless of the circuit characteristics; could be a 3A MCB circuit.
As mentioned above, some shower manufacturers state wrongly the shower must be RCD protected and some rightly the shower circuit.
Oven manufacturers who state the oven must have a 16A fuse so whatever you do it will not comply.

There is a very obvious reply to that.

I have said no, it does not rotate, and no longer do you need to follow manufacturers instructions, you only need to take them into account.
Mothers house there was an isolator behind the hob, and the sub consumer unit was next to back door which was also in the kitchen, clearly if some thing goes wrong better to isolate as you leave the house than reach over a hob. Seem to remember 350 watt limit on a motor before local isolator, but not heating element.

Does post #1 give 2 examples where the regs require MI's to be followed?
Yes I have seen the oft quoted MI. So why can a 16A fuse not be fitted?
I'm not aware of a cut off point for the isolator but over 370W there is a requirement to install proper motor OCD. This reg is, like so many others, totally ignored by thousands of people.

You haven't thought that through, have you?
Of course we know the regs. What makes you think we don't?
No.
Because it is not necessary.
Because it would mean fitting an unnecessary accessory.
Because you don't have to.
Because it would be silly.
Are you disputing the existence of the quoted text?
So what's the alternative?
Are you referring to the two quotes from BS7671 which contain the statement "...shall take account of manufacturers’ instructions..."? If so, "shall take account of" does not mean the same as "required to follow". There used to be a 'requirement to follow MIs", but that got watered down to the new wording a few years back, I think when Amd3 of BS7671:2008 appeared, so discretion is now possible, rather than the previous requirement to blindly follow MIs (even if they are silly, or even wrong).
