Aluminium/Copper Split Con

AncientMariner
I have been trying to find either a table or current figures for split-con cable where the Live is 25mm2 Aluminium (single core) and both the Neutral (7 strand) and Earth (5 strand) are 16mm2 Copper. This split-con used by Scottish Power in their MANWEB area circa 2002. Google has not been my friend...


I am interested in current ratings for buried in the ground and within a hockey stick (in wall cavity) and the max BS88 fuse that could be used by the DNO to protect - currently an 80 amp.

Thanks.

    Just re-reading your original post, I may be able to explain the problem. With the red/black split concentric, the covered neutrals were black, but the two insulating fillers were also black. This has caused most a great deal of confusion, as attempting to strip a filler does not reveal any copper. 


    Regards,


    Alan.
