fixing heights domestic

[driverman]

Hi 2nd attempt writing this! As some of know wiring new house for family member. After great discussion / debate on another thread re those damn extractor fans with timers etc. I've decided to go with wall mounted 1g light switch outside each en suite (customers request as doesn't like pull switches) and the 3 pole isolation switch at low level 450mm as opposed to high level or above the door. Will that comply with BS7671 Regs? I'm going to use a fan whereby the manufacture will not insist on a 3amp fuse.
I'd already chopped in a deep box for a shaver point in 1 en suite at face height when the penny dropped that I had in fact installed it too high. I have now installed it at no higher than 1200mm. I take it height restrictions includes shaver points also.
Now for wall mounted TV points. Many wall mounted TV points to be installed, like a damn hotel! I've installed the boxes so as no higher than 1200mm. I would like to mount them a bit higher really so as to hide the boxes behind the wall mounted TV when installed. Your thoughts,experience appreciated.

Well yes, it's going to be for a TV there will be a aerial point next to it I imagine so if you get pulled by LABC show them that part of the document.

Part M is only guidance, yes it should be followed for general usage socket outlets and all light switches, however it is fine to deviate if there is a specific reason. I have installed sockets, data points, coax plates all above 1200mm if this has been on the design. Think of wall mounted TVs in domestic situations. Commercial situations also have TVs at high level, also specific equipment required to be at high level, wireless nurse call systems just for an example. Common sense prevails in these sorts of situations and too many people lack it unfortunately now all because a guide says something different. Fan isolators are only for maintenance and are only used by someone to clean/maintain the unit, hence many are over a door as I wouldn't expect a disabled person to be maintaining as they would not be able to get access to it, this being the case, why would said person want to isolate it.

i'll disagree with you on that 1 point. the isolator is also to isolate in case of a fault, and so should be accessible to any customer.

I agree on that point, I had actually not typed it correct and actually meant fan isolator. Shower isolators I always install accessible.

The protective device is there to isolate in the case of a fault, it even does it automatically. Bearing in mind the word fault has a pretty specific meaning in this world.

As far as part M and the building inspectors goes it is like any regulations and the inspectors for those regulations. If you speak to them before you start and get them on-side you will get away with a lot more than if you wait until they have pulled you up on something to start trying to defend yourself.

Put the TV socket where the heck you like, the TV is plugged in 24/7 and not a general use socket,

Yep Going to re TV points..............Shaver Points OK about Face Height?I've been putting them there many years ago.

Just being devils advocate here. How would a maintenance guy or indeed another electrician that didn't do original job know that an isolation switch was up in the loft? should it be easily visable, accessible

Maybe there would be a label stuck on the CU telling him?

I've heard of getting your boiler serviced, never heard of getting an extract fan serviced. I thought that involved a vacuum cleaner once in a blue moon.

Regarding heights, we don't fit the likes of room stats between 450 and 1200 so why should TV sockets or Fan Isolators be any different.

And if anyone has to work at the fan, and its an inline fan in the loft...pretty damn sure they will see the isolator beside it.

To me Fan Isolators are to turn it off if its too noisy at night time. Yes it defeats the purpose of it, but a Fan Isolator can't be locked off so if one needs to replace it or work at it we would hardly rely on that

or kitchen sockets, would be useless in a kitchen 1200 off the floor.

thats the reason I don't like new builds, I think the heights all too low

I thought you could lock off the isolation switch for fans. Plastic bar clips across switch
