Aluminium/Copper Split Con

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.

  • It is likely that 80A is the maximum you will get on a 25/16 concentric. What colour is the cutout? Some DNOs will only put a 100A fuse in the newer grey coloured cutouts.
