Hi mal,
There is also a
dependence of time. I am sure you can put 1000A to a 10A Fuse, when time is
short enough. I adiabatic cases it is a function of the thermal capacity of the
fuse, the fuse wire volume and the melting point of the fuse wire. Therefore
they are separated into fast, medium, slow. If you use a fast or super fast
fuse, a 30A fuse will melt at 50A within a few seconds or earlier.

PS: I just have finished my
receiving loop with 40 windings, repaired the converter and integrated it into
my K2. Now I will watch the argo screen tonight and
hope for some signs. It becomes better and better J
Gl es dx dx!

Betreff: LF: FUSE TEST
Has anyone tested the ACTUAL blow
current for fuses eg 5A 10A 30A..
I often do not have fuses at the
correct value and FUSE down only to find that I can run them at considerably
higher amps than rated eg 30A fuses at 50A and they fail to blow. This is
intermittent use say 30% - 50% in psu's used for CW and QRS3 normally in FET
AMPS
This is normal fuse wire bought
wrapped on card.
It looks like your PA fets could be
in trouble under certain circumstances.
