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?
