Alternator Load Dump
I have a pushbutton/lever type of 140 amp circuit breaker on my 120 amps alternator to house battery feed. Not Bussman or Bluseas brand = Mistake. After less than 5 minutes of 70 to 90 amp...

I am a retired automotive engineer and worked on electrical systems and EFI.
In my occupation a "load dump" was when an inductive load (ignition coil, fuel injector, large solenoid) was turned off (load dump). The collapsing of the magnetic field caused a high voltage "kick back" (back electromotive force, EMF). Depending on the size of the inductor, This spike could be quite hogh, potentially damaging other electronics.
Typically zener diodes were used to direct this voltage to ground through a resistor.
