New light wiring help please

Yes, but countering someone who says "FCUs are unnecessary" by saying "I have an unnecessary one" seems odd.

It does.

Kind Regards, John

The FCU was fitted just in case in my dotage I absent mindedly plugged a heater into the TV socket and then had a lot of heat under the bed.

In theory the 3 Amp fuse in the FCU would eventually blow without the other sockets on that radial become de-powered. Might have a cooked FCU but ( hopefully ) not a cooked bed.

Ok, but I don't think that will change Winston's mind.

Hmmm - do you mean a heater 'under the bed'?

If so, I would think that there are an awful lot of things you might conceivably do in your "absent-minded dotage" that you would have to try to find ways to 'guard against'

Indeed, if such were what you were wanting to achieve, even with the 3A FCU you probably could/should have gone one step further, and used it to feed 2A or 5A sockets (for your TV and video), rather than "13A" BS1363 ones!

Kind Regards, John

Winston is not going to like this.

I have an FCU as the last accessory on a 4mm² radial (16 Amp MCB ). The FCU fused at 3 Amp supplies ( via 2.5 mm² ) a floor mounted double socket ( 13 Amp type ) at the bottom of my bed for the TV and video

Why, what is wrong with that, except that the FCU is unnecessary, as the plugs for the TV and video have fuses and the TV and video will also have internal fuses.

True - it's no more 'wrong' than is having a 3A FCU fed from a 6A circuit to supply an extractor fan.
