Switch or FCU which comes first in a circuit

I don't care about safe isolation. I just want to know if my heater had been left on.
Touch it, if warm it may be on. go back a few minutes later, if cooler then it is off if not check the switch .

Quite. It's hardly a 21st century method. Or a way of saving electricity.

From what people have said it would be difficult to know if its on or not.
 
Here us a thought OP.

Why not just have a switch,fuse,neon flex outlet next the to rail all in one unit ( assuming its outside the zones)?

Only one switch would be required then.
 
I'm confused...why have you deleted all these posts?
Unintended duplicates, I presume - the infamous forum glitch :-)
He has actually deleted the content of all his posts in this thread, including the first !
You're right. When I commented (10:12 pm), I hadn't noticed that he'd done it to the OP as well - I'd only noticed what were then the last three posts in the thread (9:59, 10:02 & 10:03) - which looked like the consequence of the 'multiple posting gremlin!'

Whilst that's all true, I can understand the issue, in terms of 'convenience'. If someone has been in the room fairly recently (and one wasn't sure whether or not they'd switched off the towel rail), and the rail is 'warmish', one would probably have to 'go away' for a very substantial number of (not necessarily 'few') minutes in order to determine whether it was getting warmer or cooler.

That's obviously a theoretical possibility. However, I have to say that, if it were my house, even if it was 'outside of zones', I don't think I would want a hand-operated switch in a position where, almost by definition, one might well have wet hands.

A towel rail is of no use if you only turn it on when you go into the bathroom and then turn it off when you leave.

Agreed, and it's even less use if you find it in a semi-warm state and don't know whether it is warming up or cooling down!

You do know if you don't turn it off and use its integral thermostat to keep it at the temperature you want.
 
Wow. They even have thermostats.

I think I would turn it off at night, in summer and when away for the weekend as a minimum.

That's obviously true, but I'm not sure that it wouldn't necessarily be cost-effective to keep it 'at the temperature you want' 24/7, given than many people are out at work for 8-10 hours a day, asleep for another ~8 hours and not in the bathroom for much of the remaining 6-8h.

But if you want it to dry a number of towels which have all been made damp in the morning...
 
I have a bog standard B&Q 250 Watt chrome plated electric towel rail with its own integral live, neutral and earth cables enclose and hidden away safely via rubber seal and hex screw tight fitting to main frame as per manufacturer's instructions.
It has an earth connection, therefore the body is earthed therefore you need to read up on supplementary equipotential bonding. http://www.google.co.uk/search?q="supplementary+equipotential+bonding"+(17th+OR+2008)+(7671+OR+"wiring+regulations")

I do not want a flex plate in the bathroom
So you're just going to have the flex going through a hole in the wall? That's nasty.


it looks neater than a large flex plate with metal screws fitted to hold it in position.
If you say so.

A hole in a tile will be sharp - how will you protect the flex from damage?

How on earth can the flex be damaged; no one can reach it without difficulty and the flex will never move. the hole and flex make a very smart and safe and attractive finish; one could also say that by fitting a flex outlet plate inside the bathroom hidden away from touch that the plastic hoe in the plate could cut the cable; this is not so.


Finally the circuit is connected to the consumer box 30 Ma RCDs the SFCU having a 3 amp fuse fitted.
Why a switched one?
Because I favour having a switch to switch on or off.
Why do you want a fuse at all? safety precaution.


So, such a simple job it should be; what are your thoughts on the above.
As I said, you need to investigate bonding.

Also, you've not answered the question about the lighting circuit being RCD protected. Yes it is.

Please note folks; I now have only one strand of hair hair left on my head; so would anyone in simple English state in sequence and detail how they would connect a simple bog standard B & Q electric 250 Watt towel heated rail with integrally fitted live, neutral and earth wires through a tiled studded plaster boarded wall with a pull switch fitting in the bathroom ceiling with a visibly illuminated indicater; not a flag; too difficult to see easily and also if they would power it all from a power socket ring mains circuit or if not available a lighting circuit; both RCD protected to the main consumer board; remember folks I now only have on strand of hair before I pull it out in frustration and scream for help.
 
If you insist on making a simple job difficult, then:
Circuit with power -> 3A FCU - > Ceiling switch with neon -> flex connection plate -> towel rail.

Cables in trunking, concealed in the wall, surface clipped, makes no difference.
Could be lighting circuit or socket circuit.
This is a suitable DP ceiling switch: http://www.qvsdirect.com/mk-16a-d-p-1-way-pull-cord-ceiling-switch-without-mount-block
which fixes to a block like this one containing a neon: http://www.qvsdirect.com/mk-mounting-block-with-neon-6-to-16a



The more usual and much easier method is to get one of these:

fitted in the wall next to the towel rail, and connect to a power supply, typically via a nearby socket in the adjacent room.
