Ally wiring

[gnselectricals]

Anyone know when ally was used domestically I think it's it's 2nd WW era so around 40's-50's is it ?
Definitely ally as well not tinned etc

Cheers

Yeah did seem a bit bulkier thought a 2.5 was 4mm when I was crawling round the attic

Yeah I was the same!

Sheath, although concrete/plaster of some sort had been around it at some point so may have been to do with that!

That's got nothing to do with the metal used for the conductor, that's a problem with the sheath material.
What colour was the sheath? It's normally the old TRS twin which does that (needs rewiring if it's on that condition)
The conductors look silver coloured because they are tinned copper.
I've not seen ally twin with a cracked sheath as it was PVC sheathed, but then I've only seen a few bits of it in use.

Imperial T&E of any kind appears to be much bigger than the metric equivalents anyway due to stranded conductors and thicker insulation

I would have thought Vaseline would do the job, but I'd wait for someone more knowledgeable to confirm.

Great stuff loads of that in my apprentice bullying kit [emoji23]

...And always put a teaspoon of sand,in your Vaseline....it makes a good time grate! (here all week...)

The majority of my involvement,with ally cable,bar some industrial,was as a kid,stripping ruddy miles and miles of HV,which was ally round a steel core...a job that cries out for safety goggles...

Also,the black stuff that forms around the outer surface,which the pylon lads called "atmosphere",sticks to yer hands,and stained all my school books,for a week :stooge_curly:

Apart from the 3 strand conductor smaller lighting cable with no cpc which can look tiny.

3/029 Dave:vanish:

 

[Dave OCD]

That's the one. :yesnod:

 

[7029 dave]

1/044 is even smaller.

Yes I'd completely forgotten about that! I was thinking of 7/029 and upwards!

That's the one I was thinking of ! Often found feeding very old bell transformers - sometimes there's a seperate bare earth too.

Yeah, pulled loads out in me time, that's why on rewire's always used 1mm t&e on lighting circuits the conduits where so small to get down.

you need to slim then. :stuart:

No chance of that, when was a boy right skinny crawled under floor's voids so shallow, would not even get through the trap, let alone get stuck now. tee hee
