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.

    Well spotted Mike!

    Never had to do any bailing at sea. One of the perks when I was a Radio Officer, was being in the location where I would be one of the last to get their feet wet...

    That changed once I became a Technical Officer. Remember one afternoon walking down a side passage way on a container-ship - outboard of the holds beneath the main deck and found that a fire main joint had failed and was trying to fill the passageway with seawater.  Rather amusingly, the port and starboard side passage ways were connected with a passageway running across the ship. For reasons known only to the ship builder, they had quite correctly fitted a water-tight door - the sort with four dogs around the edge to clamp the door into the frame that was set in the bulkhead. But had then gone and spoilt the water-tight integrity by cutting triangular sections out of the bulkhead, which sort of negated the purpose of a water-tight door....
