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?
Yes, I've seen dozens over the years. From 30A rewirables to 100A HRC. The lower rated ones were nearly always caused exclusively by load issues - eg husband in the shower, wife puts the kettle on and the fuse blows. Higher rated ones (60A HRC to 100A HRC) for several reasons - customer's wiring faults, overloads etc. Overloads often happened at 22:30 when the off-peak kicked in and an extra 60A of load appeared on top of whatever the household was using (you may notice your lights dim slightly at 22:30 every night, as the additional load of storage heating is switched in - you'll be looking out for that now!)
