I agree, Rob. We used two fuse blocks on our 320. Saved a bunch of weight, cost and panel space. The rule we used was this; if it was a circuit that we would consider reseting in flight...it went on a breaker. Anything that we would NOT consider resetting in flight (nav lights, strobe, transponder, fm radio, etc)  went on a fuse. Our fuses are not accessable in flight. Breakers pop for a reason and that reason is usually an electrical short. Pushing in a popped breaker in flight, especially if it's for equipment that you really don't NEED, might be putting you flight at unnecessary risk. In almost all cases, trouble shooting should occur on the ground...not in flight.

Bill & Rob,

 

I also agree. (Aeroelectric has them available, too).  I have over 40 protected circuits, 20 with the hidden fuse block, a few with inline fuses and 17 with pullable circuit breakers.  I will admit that some of the breakers could have been fuses but some are useful for testing on the ground or quick load shedding while in the air, especially for non-switched items.  These include fuel transfer pumps (shut off a selected pump while still using the automatic system), Turn coordinator, hydro pump motor (of course), flap motor, alternator field (no separate switch), engine monitor, etc.
