My 28 Chum has a simple fuse box (CF2?) - uses a piece of fuse wire but wondering what rating it should be.
Also I have been given some flat thin fuses which would fit but i do not know their value.
Any thoughts on how i could find out.
(Don't really want to conduct 'destruction' tests!

20 amp is the flat fuse that was originally fitted.

In a previous role of school science teacher I used to demonstrate fuses by hooking an about 3cm piece of the fuse wire in series with a power supply, a variable resistor(rheostat), and an ammeter, all standard items in a science classroom. With the rheostat at its maximum I would switch on and gradually decrease the resistance until the fuse, to generally muted excitement, melted - noting the amps when it did so. The fuse wire (which I would guess was British) reliably melted within an amp or so of its advertised value.
I would imagine that there isn't a non-destructive method of finding the value of an unmarked fuse, although visual comparisons with fuses of known values may give a guide.
