During the building process I got a hold of the specs for some of the common breakers used in aircraft and was surprised to see the time to trip requirements. Circuit breakers are very slow unless you deal with overloads on the order of a couple hundred percent of the breaker rating. I decided to protect all of my electronic devices with fast acting fuses. I also used LEDs to indicate blown fuses, although this feature has yet to be used. Chris Zavatson N91CZ
