[Mobile-Portable] Automotive Circuit Breakers VS Fuses ?

[D C *Mac* Macdonald]

Hi, Randy.
 
I believe that fast-blow fuses offer a far greater degree of protection
for your "stuff."  If I'm not mistaken, circuit breakers will hold a 100%
overload (double the rated current) indefinitely; not something I would
desire.  Could even start a fire in worst case circumstances.
 
Others here on the list are welcome to confirm or contradict my memory.

> Hello Group ,   Im wanting to install "overall" short circuit protection at my batteries. Im looking at using the Buss CB-185-150  150 amp water proof automotive circuit breakers with both batteries in my Ford Excursion 6.0 diesel. But over the years I have read where in some cases a fused system will offer better protection than a circuit breaker ? I cant remember the details but if anyone can give me some tips on using circuit breakers vs fuses it would be appreciated. I like the reset feature of a circuit breaker where fuses must be changed out and spares must be kept on hand if you want a fast turn around time with getting back on the air. Any tips ??
