Reference method for the old sheathed single core cables run in attic spaces with insulation

[Questforknowledge]

Good morning

I am just wondering what reference method is suitable for the old single core sheathed cables if they at some point enter an attic space under insulation.ive had a read through the regs book but still unsure

Cheers for any responses

The same as twin and earth and 3 core and earth.

Hi - if the cable is under insulation it’s heavily de-rated I’m afraid. Possibly method 103 from Table 4A2 which then sends us to Table 4D5.

All depends on thickness of insulation, how many yards of the cable are covered.

Yards, @telectrix ?
electricity comes in metres these days.

meters. you put a shilling in and the leccy comes on. andi see the forum censors have been. half my last post deleted. seems a senseof humour is sadly lacking with some.

Yards - enough space for a dog run ?

From reading those sections though it seems pretty clear they are only for twin and earth style flat cables and so I wouldn't consider this cable applicable so I'm still unsure

If the cable you are looking at is physically the same materials than regular t&e, just go with it.
Is it single-and-earth you’ve got there?

The Cable you have described is 'twin and earth style' it conforms to the same standard and is constructed from the same materials.
This cable is 6241Y, twin and earth is 6242Y and 3 core and earth is 6243Y.

Is it not 6181Y

We don’t know until OP confirms.
Singles and sheathed, or single and earth sheathed.

As long as he doesn’t say it’s 6491X.... then that’s a different issue

It appeared to be a 6181y cablebwithout an earth. Just one single core grey sheath and black insulation inside of that
