I'm in general agreement with Bob, but there are some details.
(1) You don't want to melt you power supply wires. If you trust
the power supply device to properly current limit, then you
don't need a fuse. If you are using something like my old
solar/deep cycle battery supply, you definitely
should be less than
0.5 volts.

A study of fuse (and breaker) specs is worthwhile. In general, fuses are
rated by average current, with considerable allowance for

Same for auto installs... I see far too many fuses at the radio end of

Dave and all,
Placing the fuse near the power supply end is the way to do it.
In the event of a short, the power wire can spew metal and start a fire.
Always fuse near the power supply. A fuse at the equipment end will
only protect the equipment, but will expose the wire from the power
supply
Hi,
I am unsure what you are asking... If you are asking about fuse values,
I select values a bit above the max peak current I expect. For my K3 I
use a 30 amp fuse.
If you are asking about voltage drop, and want to know what the K3 sees,
there is a built in volt meter in the K3, (see the
I have fused my Elecraft radio equipment with inline power pole positive
and negative ATC car standard blade fuses.
I am now doing an audit of the fuses in my system to make sure they are
appropriate for the equipment they protect. I realize there are internal
fuses in many cases, I prefer
