Spur security light

It says 24amps here http://www.tlc-direct.co.uk/Products/CA2dot5G.html
That would be for the cable in trunking or conduit and no other detrimental factors.
27A if clipped direct.

Electricians (good ones, anyway) tend to have a greater regard for the safety of others and their reputations.

And so do 'good' DIYers

If a 2.5mm spur is run from a soket outlet, the protection is provided by the breaker, unless there is an FCU fitted.

How does a 32 Amp circuit breaker adequately (safely) protect a 2.5mm unfused spur?

You do realise Chapeau that it doesnt!

I wonder if anyone else, all these "expert" sparks, will come and agree?

Or is it how i originally thought, they are all scared to say that even tho everyone does it, it is by calculation and stated figures. WRONG!

Hence my original question regarding a 1.5 cable supplying a fixed piece of equipment in a security lamp with maximum draw of current 2A. Which i do realise is totally wrong and I would never do it but someone has!

I really do think this is left to rot in the archives now, as from what i gather there is no answer to prove it correct. and it is not me searching through posts to find someone who agree's with me. I prefer using the facts and there doesnt seem to be any.

Thanks for all who have contributed, it has been fun!

P.S. 1-0 down, 4-1 up, Ryan Taylor wrapped it up TOON ARMY

The Ring was a fudge (there is plenty to read about this) to allow smaller cable to handle higher current than it was designed to carry. Each socket is fed by 2 cables with current flowing in both directions. The spur is a single run of cable. The regs state one spur, or a spur fused at 13 A feeding multiple sockets, to prevent overloading of the cable in the spur.

Yes, we know this.

the fact is though that the weedy little 2.5 cable is by values stated in the regs etc not upto the job to carry the loads that could effectively be connected to it, or not upto the job to enabel a 32 breaker protect it.

It is against everything you are taught when selecting cables that are upto the job!

Did anybody see routledge goal last night, oooh what a beauty!!!
