Perhaps I've had a sheltered upbringing, but it's occurred to me that I've never encountered a blown cut-out fuse (e.g. a BS1361 BS88-3). So have any of you seen one? How rare are they? Any interesting or salutatory tales to tell?
Some due to faults, a short on a 32 amp circuit may take out the cut out fuse.
Others due to simple overload.
One recent one was a 20 amp cut out, though fitted with a 25 amp fuse. The fuse was not blown when inspected, but the presence of a box of spares suggested regular replacement.
Another recent one was a local farm, the 100 amp fuses in the 3 phase cut out blow "regularly" I was asked to supply "stronger" fuses but declined. Milking machinery and electric showers to blame. I suggested a supply upgrade, or a coal boiler for hot water/central heating.
