Cartridge Fuses in Domestic Fuse Boxes.

Zoomup
How many domestic fuse boxes have you come across within the last year that have B.S. 1361 cartridge fuses in them? I came across one today. You know the ones. The 5 Amp cartridge fuse is just a little shorter than a 5 Amp. 13 Amp.  plug fuse. The 15 Amp fuse is coloured blue, 20 Amp yellow and 30 Amp red. The shower fuse may have been 35/40 or 45 Amp. I seem to remember that the 45 Amp carrier was orange. I have an old Wylex carrier here that has a brown cartridge fuse carrier and an orange base. I was impressed years ago with a cartridge fuse maker's video advert. It said that when a fuse blows you fit a new unused cartridge fuse that affords great protection and reliability, unlike with a circuit breaker that after time and many operations may become unreliable. That impressed me at the time.

    There were fuse testers available in shops that were battery operated and had a torch bulb in them. A simple continuity tester. You placed a cartridge fuse on their contacts and the light lit if the fuse was good. The design allowed cartridge fuses of many lengths to be tested by having a long brass contact strip. Or if you were lucky enough to have a school child interested in physics or science they could test fuses using a battery and door bell or a cycle lamp.
