Remove the plug from the vacuum cleaner and hard wire the lead into an FCU, that will stop anyone plugging the vacuum cleaner into any 13 amp socket. Simples.......

Great idea. FCUs are allowed on lighting circuits, too!
No.
I thought we were discussing a hallway socket for a doorbell but anyway a kettle would trip the CPD. Scenerio workman doing job outside plug in extension lead to a kettle to make a brew.
Thanks, but I have an old Panasonic vac in the loft and a socket up there spurred off the upstairs ring.

Seems a stupid idea.
They'll probably have an extension lead with a MIG welder and an engine hoist plugged in as well.
Don't you find that there's so much to worry about.
FCSs are not used or needed on lighting circuits as they are adequately protected and even a 3a fuse offers no discrimination against a 6a MCB.
This is exactly your problem. I said FCUs were allowed. They are.
They are used on lighting circuits, There are millions of them installed in accordance with fan manufacturers' instructions.
You have just demonstrated exactly your problem. YOU think that things should be different to they way they are. YOU argue against something that is expressly permitted in the Wiring Regulations. If you want the regulations changed, join the committee that writes the darn thing.
All I (and others) ask is that you take your constant moaning drip feed off this forum.

There is no need for them on lighting circuits. Fan manufacturers instructions are wrong and as such don't have to be followed. What does one do when fitting such a fan in one of the many countries where FCUs are not available nor complient?
We seem to have a problem where people blindly follow incorrect instructions without engaging brain first.

So, why do you not contact them and put them straight. Why bother the rest of us with it?
It was meant as a stupid idea, if you can't defeat the stupid person then join him ( for a while at least )
What happens when a fan goes short circuit and the 16 amp MCB permits more than 4kW of energy to be dissapated in the fan.....?
Oh yes the installer ignores the manufacturer's lack of instruction and installs a fuse to limit the current that a shorted fan can take. Heaven forbid the installer refers to it as an FCU ( translated as appropriate to the language of the country.

I love the LAP grid system, I have a few times when fitting a spur swapped the double socket for a LAP grid with a fuse switch and single socket, using this one can fit a socket on a lighting circuit protected by a 1A fuse, the question is however would a 1A fuse rupture before a B6 MCB?
Be it a sticker do not remove, or a fuse, or even some physical method to stop its removal and swapping for other item there are ways to use a 13A socket on the lighting circuit without danger.
In my house with a central stair case loosing power to lights could be dangerous, so when I fitted a RCD to the lighting circuit some 20 years ago I did a risk assessment and swapped the landing lamp for a fluorescent and fitted a remote emergency light unit in the loft, so in my house it the lighting power trips there is not danger, inconvenience yes, but no danger, also emergency light in garage where the fuse box is.
Tradition from the days when lights and power had different meters was to power light things from the lights even if illegal, when we went to a single meter for both lights and power using light sockets for power was no longer against the law, and my grandfathers house had just 2 x 15A sockets one in hall and one on landing for whole of house, so it was common to plug the smoothing iron into the light socket and there was a BA22d plug on the iron, plus a two way adapter for the lights this also kept the iron lead out of the way.
Post war we did have more sockets in the house, my dads house had 5 he told me, so the practice of using the lights for power reduced, but never the less even today we have 2 and 5 amp round pin sockets fitted to lighting circuits clearly to power standard lamps, but open for abuse easy enough to get 2 or 5 amp to 13 amp adaptors, although the supply of BA22d plugs does seem to have dried up, I have one in my testing box makes testing safer and easier.
However the point is tradition has been to power items from lights, be it a fan or TV signal booster it is normal, and with wallmart power supplies (not calling it a transformer) to power TV boosters or LED lighting strips then we really have no option but fit 13A sockets to lighting circuits, it is not the consumers fault, it is the manufacturer, I have had a few wallmart units with changeable plugs, you select the appropriate one and slide it in. So you could use Schuko sockets for lights which are not polarity fixed but neither is a BA22d socket, however our governing body says we can't fit Schuko sockets because the polarity is not fixed, so we are forced by the regulations to fit 13A sockets to lights as 2 and 5 amp options are not provided for wallmarts.
Be it no FCU which will take 16A fuse, or no option but use 13A socket one has to work with what we can get, so we often have no sensible option but use a 13A socket on the lights.

It won't. Power =I squared R. If R is zero the power will be zero.
