|
|
On the firewall of the BSA was a great big fuse, two sprung posts with a 'paxalin' looking blade between with fuse wire across the posts, It is under a black plastic cover held in place by a spring clip.
Does anyone recognise this description. (1) Is it essential, (2) What is the correct rating and (3) where doss it fit in the circuitry?
If anyone wants a snap of it, please email me and I'll try and send it.

Big is relative so a pic is required. What does it supply? _________________ Rover P2

Good afternoon Phil,
that is the reason for my detailed description, I cannot figure out how to put snaps on these posts (I have one ready).
I have no idea what it supplies or protects, that's my reason for asking.
Perhaps Paul Fairall could explain in layman's terms?

It sounds like it might be a knife switch rather than a fuse but perhaps it wasn't making good contact and someone has simply wired it shut with wire.

Good evening Peter, by knife switch, do you mean a blade fixed at one side and pivoted to make contact. If so no it aint. The paxalin 'blade' is inserted just like a spade fuse.
I do wish I could send a snap...

Tony,
What you describe sounds like the mains box fuses in my house. You have a black Bakelite piece about 1 1/2” long with a blade at each end. Between the blades along a longitudinal hole runs a bit of fuse wire connecting the blades. We’ll call that part the male and the female would be where the wires are connected. A PO has probably been a spark and used what was to hand to make up a ‘master fuse’. Does that sound familiar?

Actually, I thought it seemed to the type of mains fuse seen 100 years ago and obsolete by the 70's.
47JAG - if you have them in your home I suggest an urgent safety electrical inspection. These fuses can spray hot molten metal around when they "Blow" _________________ Rover P2

Phil,
These are mid-60s vintage. While your point may be valid since all fuses ‘spray hot molten metal’ when they blow there is a containment capability in these in that the fusewire runs through an asbestos sleeve and is enclosed inside the fuse holder. The next owner can rewire the box.

Interesting communications all, 47jag, we also still have the type of fuse in our domicile as you describe. Must get round to having them all replaced with circuit breakers soon.
Have you tried to find fuse wire???

Tony
The ironmongers in the Bath Guildhall Market has plentiful supplies of fuse wires on little cards.
Not 6d any more, though. _________________ Mike - MVPeters at comcast.net
