I tried an experiment once when I needed a 1500V fuse at 15A. IIRC, a
single strand from #22, which I believe is made from 7/32, will break at
about 7A current. I used two strands until I could get the correct
fuse. High voltage fuses are also EXPENSIVE. Current capacity for wire
is easy enough to find. I can't remember seeing a list for melting point.

Good idea, Jim. I'll have to check that out. The problem seems to be when
I talk to these fuse manufacturers is the relatively low current rating for
such a high voltage (1.5 amp @ 5kv). Thanks for the idea.

Hey Rick,
Something just occurred to me, wonder what kind of wire is in
fuseable links used on automobiles?
If that is fuse wire, one could buy one and remove a strand or
whatever you need. Auto parts stores have several different sizes
of the fuseable links.
Does anyone on the board know what kind of wire they use?
