ever seen a blown cut-out fuse?

wallywombat
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?

    Even with radio teleswitches, start times for economy 7 or similar off peak tariffs are somewhat staggered. Mine runs from midnight until 01-00, then full price from 01-00 until 02-00, then off peak again from 02-00 until 08-00.

    My neighbours time are from 01-00 until 08-00. Another neighbour is from 23-00 until 06-00.


    Staggering the "off" times is of much lesser importance than the "on" times. Considerable load is connected at the commencement of the off peak tariff, but relatively little is disconnected at the end of the allotted time.

    A lot of the load is thermal storage space heaters and hot water tanks, these have their own thermostats which are often satisfied before the end of off peak hours. Likewise charging of EVs, most will be "full" before end of the off peak hours.
