There is one type of load that can be reset after an overload, a motor. HPUs,
trim systems, door seal pumps, autopilots and cowl flap actuators all have
motors and should use breakers for overcurrent protection. The alternator
field lead should also have a breaker so that the alternator can be isolated.
The trim breaker should be set apart from the others so in a runaway trim
situation it can be located, and pulled, quickly.

Blade type fuses are suitable for most other applications. I avoided Faston
spade terminals in my plane and am glad I did. I have only three of these
friction connections, two on the Hobbs and one on the alternator, and one
(alternator field) has given be trouble. Not a good average. I used solder and
heatshrink almost everywhere and have been rewarded with a very reliable
electrical system.
