Adding fused spur for bathroom extactor

[Dave K2]

Hi - I'm planning to fit an extractor with timer to a bathroom, switching on with the lights and had bought a fan isolator switch, but reading the Manrose instructions they insist on double pole fused spur with 3A fuse.

I think it will be easiest to fit a switched fuse spur and not bother with the fan isolator - this will be fitted outside the bathroom above the doorway.

Just figuring out the easiest way to fit this in since the extractor needs live and switched live.

Current setup

Suggested:

I have also seen options that suggest to use a double pole pull switch instead and then only the extractor fan is protected by the fuse - suggestions?

Isolate the main supply before making any electrical connections. This system should be installed by a qualified electrician. • Whenfittingthroughanexternalwall,anexternalgrillemustbefittedatalltimes. • Fanshouldonlybeinstalledbyfixedwiring,aflexiblecordshouldnotbeused. • Theapplianceisnotintendedforusebyyoungchildrenorinfirmpersonswithout supervision. • Youngchildrenshouldbesupervisedtoensurethattheydonotplaywiththe appliance. • Precautionsmustbetakentoavoidtheback-flowofgasesintotheroomfrom theopenflueofgasorotheropen-fireapplianceswhenmountedinoutside windows or walls.

Happy to hear any suggestions if what i suggested is dangerous or incorrect? First thought was to check with people who know best how complicated a job it is, since when I checked the price quoted for wiring up the fan was around £200, and since I've got 2 to do, and it's only electrics needed since roofer is fitting the vent tiles and I'll mount the extractor and fit ducting etc seemed quite steep - but if someone can explain briefly maybe it will make sense.

Or you could pretend to be a Mechanic, or go on a 5 week Mechanic course, it's only a car for Gods sake how difficult can it be?

Depends on you really doesn't it? I saw a chap paying halfords £10 to change his indicator bulb recently - would you have done it yourself? Is the halfords person 'qualified'?

Thanks for the copy and paste but I've got the correct instructions right in front of me - I have read it.

If this is meant to be a lecture then thanks. But, I've just looked at instructions for fitting some downlights:

This light fitting has been designed and manufactured exclusively for B&Q These instructions on wiring and installation are provided as a guideline to assist you. Some experience of electrical wiring and do-it-yourself is required to install the light fitting. If at any time you are unsure of how to proceed, please consult a qualified electrician.

So I'm safe to do the lights, but not the extractor?

Do the B&Q instructions inform you that all electrical work must be tested and certificated by a competent person in line with the wiring regulations to ensure safety and that work in a bathroom may be legally reportable to building control ?

You should be "competent" when undertaking electrical work. Would hardly say you are competent if you need to post on a forum. If I didn't know how to change a lamp in my car I would pay a professional to do it I wouldn't check on a forum. Especially when we are talking about electrics, you may succeed in installing what you want but will it be done to regs and in a safe manner?

Sounds like you've made your mind up to do it any way so just be careful, most sparks I know ( wrong or right) dont bother with the fuse , been debated many times as the difference between a 3 amp fuse and 6 amp mcb wouldn' make much difference, they just connect into lights with switch and permanent and neutral through isolator then to fan. Having considered manufactures instructions but took no notice

TBF - I searched for the answer before asking it, and quite a few 'competent' or 'qualified' people seem to either - say they don't bother with fuse, question if it has any safety value over 6A MCB.

Have you ever needed to ask a question, or check something with anyone - did that make you incompetent? Have you used google, ever? Why would you?

I'm happy to get a professional in if it's clear to me that it's not safe to do it - but only reason I've been told is the instructions saying get a 'qualified electrician', even though similar job (lights not in bathroom) don't say it. So unsafe in both cases? or just when it says it?
As far as talking about car DIY then yes, there's lots I have done before - my brother's a mechanic - so I know what I'm capable of - it's not difficult to assess the situation and decide if you feel confident to tackle something. But as far as this job goes I assume it's incredibly complicated since no one has offered to explain it!

Thanks for the clear and honest response!

Incredulous.

If you aren’t testing your work with a calibrated multi function tester you are as far away from competent as you could possibly be.

Your insurance company will more than likely argue the same.

Your craftsmanship and “gut feel” doesn’t come into it.
