The core concept of a fuse is that it provides a weak link in the
system which will break first in the event of device malfuntion in
1.) spare other components of the device from destruction, meltdown,
2). to keep the device operator from getting blown out of his/her
socks due to short circuit.
The fuse in the unit is the one which was specifically selected by
the unit's designer to allow for safe and dependable operation under
normal circumstances, as well as reliable protection in the event of
a fault with the device. If your fuses are blowing consistently,
they are probably doing their job in both protecting you and
notifying you that there is a problem elsewhere in the unit. Fix
that problem, and your fuses will stop blowing. Substitute a
non-recommended fuse and you have not only failed to fix the
problem, you have eliminated a safeguard which may currently be
protecting your unit from a total self-destruct, and/or protecting
you from high-voltage shock.
Do what you need to do to fix the root problem, for your own safety
if nothing else.
