Is it com= mon to get an amp draw intermittently higher than breaker rating from compo= nents that does not really justify increasing wire size & breaker ratin= g?

Up until this corrosion incident fuses have wor= ked for me, But have always used fuses & wire size much higher than com= ponent requirement, that way if a fuse blew, there was a substantial fault = somewhere that caused it. btw. only time a fuse has blown is on the ground = when some idiot stuck a screwdiver where it shouldn't go. but then I ha= ven't flown much either to say it wont happen in the air.
