TV in bathroom - regs and safety

NO. FCUs are not used or required on lighting circuits.
Have you read any MIs for extractor fans recently?

I'm not suggesting that it's sensible, but ...!! You can argue that FCUs are not 'required' because of the MIs, but they most certainly are 'used' - because of the MIs.

No, I haven't read them. MI are frequently wrong and no one should follow wrong instructions. Certainly the same extractors can be used in mainland Europe straight on to 16 amp circuits so obviously internally protected. And as we all know the fuse is to protect the cable not the appliance. Let's say FCUs are not required on lighting circuits and should not be used. They serve no purpose especially if the citcuit is already loaded with several hundred watts of lights.
 
My loft has no socket circuits in it, but it does have a lighting circuit. How do you think I should power my aerial amplifier?

(Clue: a suitably labelled 13A socket-outlet)

A 5amp round-pin socket and plug.

That's a fair bit better than saying that they are"not used" - which is ridiculously incorrect. However, "should not be used" will, to many people, imply some rule/regulation - and I need not tell you that no such rule/regulation exists.

As someone pointed out earlier, that wouldn't stop someone fitting a "5A" plug to their welder/whatever. In fact, if I look in a dusty corner of my cellar, I might even be able to find you a "5A to 13A adapter", so you might not even have to change the plug :)

To say an FCU should not used on a lighting circuit is a bit ridiculous.

Someone already pointed extractor fans supposedly need 3 amp protection.

It's not unheard of that a security alarm can be found on a lighting circuit. Here an unswitched fused spur (3 amp no doubt) would generally be required, often by the MI, and to act as some form of local isolation, as a switch could be accidently switched off.

I already suggested that in no. 3 below.

1. Use a clock connector on the lighting circuit.
2. Use a BS 546 2 amp socket on the lighting circuit.
3. Use a BS 546 5 amp socket on the lighting circuit.
4. Use a 13 amp socket outlet spurred off the ring final or socket radial in the room below. Make it a double socket. Then you can use a vacuum cleaner to clear up the mess afterwards.
5. Use an aerial amplifier that is phantom powered up the coax from a power supply behind the TV.
6. If the aerial is in the loft move it outside on the chimney and most probably you won't need the amplifier.

No.5 is by far the most common method with no.6 a close second.

That's all very well, but it's of little use to the OP whose question/problem related to getting power to a TV in the bathroom.

As I keep saying the fuse is to protect the cable not the appliance which should be internally protected. These fans and burglar alarms are used in Europe straight on 16 amp circuits so the MI are clearly wrong.

I also pointed out a 3 amp cartridge fuse would almost certainly have no discrimination against a 6 amp MCB especially if that MCB was already carrying the current of several hundred watts of lights.

FCUs were invented because we have 32 amp ring finals which is why they are not found or compliant elsewhere. They are not needed on lighting circuits.

You say "supposedly" but that implies that actually they don't.

Do you, and everyone else, think it appropriate that such a demand should be classed as "manufacturers instructions"?
Why is local isolation needed for an alarm system?

There are lots of things which may be a "good idea" but for manufacturers to demand them in their instructions, when not required for electrical reasons, is, I think, overstepping their remit - if indeed they are written by someone who knows what they are talking about.

You do, indeed, keep saying that, but you nevertheless seem to have a problem with a circuit wired in cable with a 16A CCC being protected by a 16A OPD, if it happens to be called a 'lighting circuit'.
