Hi,

Sorry for the delay in responding - I forgot my password

I thought the red spot might indicate the status of the fuse by some sort of heat sensitive ink. We have some fuses with the windows and of course the BS3036 rewirables!

That is an Elevated Temperature 10mm dia tensile from our test lab.
I am not sure of the cable size or type but it might be SY cable, I will ask tomorow.

that memory board is a Postage Rate PROM, some of you might know that UK postage has increased from Monday and that tells the scales how much postage to charge to the franking machine.

Those are not ribbons, they are laces, 2 pairs is the style they are Osiris D3 2001.

I have found the Red Spot company and all of their fuseholders have 2 red spots!

These fuses are pretty common here.
As are the holders.
GEC HRC fuses are taking over from them though in the higher amperages.
Red-Spot is a trademark of English Electric BTW.
I would have thought that a few of your UK guys would have known that.
There is one thing that I personally hate about this particular fuse carrier design and it shows that it was designed by a draughtsman, not an Electrician.
That being, try and pull one of them fuses with rubber inners and leather outers on your hands, it's not possible!.
GEC had the good idea of putting a secondary pulling flange on the fuse carrier, in all sizes from 32A upwards.
GEC is the preferred fuse-holder of our PoCo.


{Edit: Under our current Standards here, if you withdraw a fuse, the live contacts shall be shrouded, while the fuse is withdrawn, a few types of fuse-holders here were withdrawn from sale because of that fact.}

I have been reliably informed that the cable is/was tri-rated cable for additional flexibility, this fuse is mounted inside a 6foot square cabinet which regularly catched fire here and there, the whole kit is connected to 250A parallel breakers (surely a violation in its self!) makinig 500A
