Newbie: stuck fitting a new ceiling rose

[Debs]

Hello everyone,
Just came across this forum looking online for help with what I thought would be a simple job and has now turned into a nightmare. I'm fitting a new ceiling rose and I'm confused with the wiring - esp. the loop part. In essence how do I get these wires in the right places on this fitting below?! I get the live and neutral part but it's the loop that's thrown me....

I'M MORE CONCERNED ABOUT THAT ALUMINIUM CABLE. well past it's useful life.. time to call in an electrician.

If you don't understand what and how to wire a ceiling rose, then you shouldn't be doing it. For safety sake get a registered electrician to finish this for you.

The problem is you have now taken the old one off and it is impossible to say which ones are the loop and switch. I agree with #2 that it looks like aluminium conductors and you need to contact an electrician. Those terminals at your new rose are likely to just break the aluminium as they are not suitable for aluminium wires.

Reckon I could hazard a guess to the switch one.

 

[telectrix]

a guess and a reel of 5A fuse wire?

3 plate wiring is not the best for DIY, seeing that you have completely pulled it apart, my advice is to employ a sparkie to reconnect, 5 minute job for such.

Must be the doubled over black as the switch live.
Come across tinned copper from time to time but never aluminium conductors.

They are definitely ali they are shaped square as well which is unusual for a small csa.

Without any test kit you are going to have to rely on a bit of guess work and the bang test.

A domestic installer could sort that couldn't he/she

a pp3 battery, bulb and a bit of wire to ID the switch wire. job's good (till the ali conductors snap off.

Off topic, but for the purposes of my education, are these aluminium conductors?
I was aware tinned copper has been used in cables but didn't realise aluminium was ever used in small CSA/domestic cables.

They certainly look like they are. Back in the seventies when the price of copper shot up some manufacturers, BICC being one of them produced copperclad aluminium T&E generally in solid core 1.5 and stranded 4.0 sizes. It was copperclad to prevent the aluminium from oxidizing and can easily be mistaken for copper, the give away being it breaks very easily when connected at tunnel terminals for which it isn't really suitable. The OPs is quite unusual as it is not copperclad and the certainty it is not tinned copper is that there is no copper showing where it has been damaged through termination.
