The cutout is made by BICC, the 60A fuse had a small fuse carrier, so had to be swapped over for a larger size (dimension) to accept the 80A. Meter tails upgraded from 16mm to 25mm with 100A double pole switch, would have been ok at 16mm but thought would change at the same time. 6mm SWA is for outbuilding. Hazard tape to identify supply cable behind plaster. For reference only
I always thought that the 80A was the same size as a 60A or at least they were when i worked for the Lectric board.
When the DNO arrived, the girl realised the 80A fuse was larger in size, although it fits into the outer case, the copper cage wouldn't accept the large 80A fuse. the pictue of the fuses on the sink show the diffeenc in size: They had a spare 80A fuse unit in the van.
