6mm flat twin NO earth?

D4G

So I came across an old cooker circuit fed from what I thought was 6mm T&E however it has no earth.  I didn't think it was a thing but it appears it is!

So how would the cooker have beed earthed?

Whilst on the subject of old cables, what were the sizes of eg 2.5mm twin and earth? it has the stranded conductors, is it still 2.5mm with 1.5mm CPC?

    Ashathene was a type  of polythene - but not like modern XLPE,  just plain PE, more like sandwich bags and  the filler in the cladding at Grenfell. It has a slightly slippery feel, and burns rather well..

    There may have been more than one variant of hybrid rubber/plastic cables, all sorts of things were tried as cable makers modified their production processes to the new materials.


    Rubber would look and feel a bit like bicycle tyre if in good condition, and goes all flaky and disappointing  once perished - which by now most of it has, though a few samples in cool dry conduits are still OK in service.
