And yet, airliners, those big machines that are responsible for carrying hundreds of people at a time safely to a destination, use breakers exclusively. Lots of them. I wonder why that is so? And as I have mentioned before, I have found fuses failing just because they were old. The fuse strip is trapped between the glass tube and the caps, and those connections oxidize and present resistance that heats the fuse and fails it even when it's not anywhere near max load. I have also found breakers that fail due to oxidizing contacts; they also are a thermal device and resistance causes heating. However, the old breakers were 40 years old, and switches suffer the same fate whether they're fused or breakered. The fact remains that age hits everything hard. And the fact remains that a popped breaker is visible, a fuse is not unless it's removed and inspected. Ever try inspecting a 2-amp fuse in the dark? POHs give advice on resetting breakers. So does this: https://www.faasafety.gov/files/notices/2009/Dec/SAIB_CE-10-11.pdf An excerpt: Current guidance for part 25, Transport Airplanes in AC 25-16, Electrical Fault and Fire Prevention and Protection that has been accepted for small airplanes, is to recommend that no pilot should reset any circuit breaker more than once. Pilots can keep replacing fuses just like they can keep resetting breakers. It's a training issue, not a fuse-versus-breaker issue. Worse, a blown fuse is too easily replaced by a larger fuse, or wrapped with aluminum foil, to get the system going again and risking a fire. Impossible to do that with a breaker.
