CU Entry, Old 1980s cable (?)

[telectrix]

I'm also a complete geek so I'm putting in type 2/3 SPD, help protect my equipment but also trying an AFDD on my main ring mostly just out of interest.

afdd's and spd's????? more money than sense... fur coat and no knickers.

Only 1 AFDD!

If the cable inside is Twin and earth, not singles as I thought, (maybe another system) then just trim the outer coloured sleeves off at the wall and treat the T&E as normal.

sort the bloody thing as rear entry to the CU. if i doubt, squirt some funny foam.

I think I'm stuck again, I need 9 cables to enter the new CU but these cables are 20mm X 10mm and most entry points are 20mm x 20mm.

So drill bigger holes in the box!

So the options I identified were:
1) Some sort of grommet specific for this oval cable
2) Perhaps the whiska membrane grommets work, never seen them before. Sounds like they will.
3) Worse case scenario I have a box next to my CU that crimps all these cables into new grey twin & earth, which would then be more normal for entering the CU.

I think Wiska it is. No one has recognised this cable yet then?

Why woukd you need a special grommet? The usual round open grommet you'd use with other cables will be fine.

Why do you think adding extra joints in to the circuits woukd be a good idea? You'd still need a suitable grommet or gland at the entry to the joint box.

Absolutely not T&E within that whatever it is.

I shall give standard grommet a go, it's just going to be tight as the oval cable is 20mm and most holes are 20mm, the grommet will use 1-2mm, I'll just have to squeeze the cable a bit.

Thanks for the help chaps. Clearly my 1986 building is a little special haha

I remember that stuff being introduced in the late 80's. Never really took off as it was fairly expensive.

if its to big you could use some m32/25mm glands instead

AFD on a ring final?
Why not just terminate that cable into some trunking or an adaptable box and then bring it into the CU else use a plate to raise the CU off the wall for rear entry?

I'd ditch the lot .
