Since this is the umpteenth time that the fuse vs CB topic has come up (not just on the rotary lists but aircraft list in general), and certainly won't e the last, I decided to do something different than just spout my views on the topic.  I surfed the net and see if I could find anything on it.
 
Here are some of the URLs I found of interest.
 
This guy actually did some tests and found among other things that a fuse rated capacity can slowly degrade with repeated high current flows even if below its burst point.  But, read it and draw your own conclusions.
 
 
This one has an interesting summary, but since they are presented by the makers of CB can be considered Biased
 
 
 
Another maker of CB propaganda, however they do point out that you can not test a fuse since it is destroyed if it proves it works at the specified rating where as you can a CB
 
 
Here is Bob K's and his well reasoned  argument  FOR fuses
 
 
 
It appears that there is as much debate outside the aviation community (or more) about fuses Vs CB.  It appears to me the CB is winning there simply because of convince rather than any technical advantage -  That is once the problem causing the short is fixed, you simply reset the CB rather than trying to find a fuse of the right rating and shape to replace the blown one and possibly sticking in the wrong fuse. And you know Americans - convince before all else {:>) -  At least that's the way it appears to me.
