[Mobile-Portable] Automotive Circuit Breakers VS Fuses ?

[N5WV]

Clete ,  The unit looks and feels quality and the Buss name is an American standard. There products have been used and still are spec'd in most commercial , industrial types of construction. I would like to install these breakers but with the amount of money invested in this emcomm vehicle and the heavy gauge high amp fuse blocks /  fuses being easilly available with the fuses great "track record" of quickly blowing when a short circuit accurs Im going with fuses.  Thanks for your input.   Randy  N5WV   ,

Buss fuses, changed to Bussman, then to Cooper Bussman, have been 
THE industry standard since year one.  Why do I think that?  Because 
the the old AT&T Bell Telephone System used so many of them.  They 
came in all physical sizes from a 30-pounder to a 3AG.  Trivia, but the 
larger ones get old and need to be replaced, so the large power panels 
had two fuse holders side by side.  Slide the new one into the slot, 
operate a change-over switch, pull the old one out, and put an entry into 
the log book and the bring-up file.  If you have one with a small hole, that 
fuse could be filled with a white powder.  That's a slow-blow kind of 
thing.
