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.

    The rats nest of green and yellow sounds like the supplementary bonding crisis of the 80s! <grin> Every bit of metalwork had to be bonded to every other, even if it was directly connected to it by a 22mm pipe because 'ptfe' tape :)


    I think I pre date you by a few years because dad upgraded our wylex CU from rewireable to pushbutton MCBs that definitely WERE colour coded (I even have a few now in my collection). The later switch ones were also colour coded at first, but then they went to a grey toggle. We still have a few of the later ones on the van for elderly customers who struggle with rewiring fuses but insist that anything above a fiver is 'too expensive'. Usually put in gratis.




    My customer cut through his electric lawnmower flex in the garden. He blew the 15 Amp blue cartridge fuse in his fuse box. He sought a replacement and found them at a local hardware shop. He had to buy two in a packet. The cost was just under a fiver.
