Unidentified cable in loft - advise needed!

[westward10]

Will check with the neighbour before going for the cut

Yes, that box is quite antique! I switched off the main breaker and had a look inside, wiring looks neat so just left it as is

Can we see inside the box.

Sometimes cables would be running through lofts for Redifusion TV signals

I'd check with the wife/girlfriend first actually...
It's quite a big incision...

No nasty surprises and if your missus gets pregnant then errrrr your stuffed.....

I love the way the joists are held together with redundant galvanised tray work.

I reckon that's a truss nail plate,fella

I didn't say it in case he was just taking the ----.

IT could be a communal tv system like the old Redifussion TV set up we used to have in Basildon that used cable like that and it was run internally from house to house

There appears to be an octopus box underneath the cable, they’re a rare sight these days!

Got one like it in our loft Dave plastic with Volex on it all the cables have stickers on ends eg switch 1, light 1 etc.

This one is a little older than the one in the OPs picture.

It has a tag attached detailing the installer and the inspector... it appears to be dated 1957. And yes... that is all rubber insulation

 

[Dave OCD]

Did it have porcelain connectors inside ?

No, it's a black bakelite carriage with brass terminals. It's packed quite tight and has been tinkered with since it was installed as there was a PVC cable linked in.

I'll snap some pics of the innards.

I know I'm abit weird with this, but this place is proving to be a treasure trove of old cable samples for my collection

This is one that I saw in a house last year the lid fits flush with the ceiling there is one upstairs and one down.

OP - is it a sheltered housing esate? If so then it may be for a warden call (pull cord, etc.) system. Often use 10 core multicore as the system cable.

As promised... some pics of the 'Octopus'



And for the younger members who's experience of old rubber cable may be very limited... here's a selection of cables. On the outside, the one on the bottom looks in reasonable condition, but when I was pulling it out, you could hear the insulation inside cracking so I peeled it open to take a look. One of the joys of rubber... over time (or with a liberal application of heat) it can dry out, become brittle and just fall away when touched.

That box was well done internally SC, and most of the lighting cables back in 1957 appear to have a cpc too ! It's a little bit of history and also a little sad as whoever did it will be very elderly or gone by now.

I was impressed when I opened it. It's possibly the part of the install that was in the best condition.

Most of the accessories have had insulation tape wrapped round conductors and one place where a bunch of cables ran near the heating cables the insulation fell off when I touched it.

The picture is deceptive though... I was surprised when I saw that CPC in the lighting circuit cabling because to that point I hadn't encountered any when cutting the old cabling out. Lots of metal switches too. Scary.
