Electronic Circuit Breaker

[rotorwrench]

Don't forget that a dead short to ground is a lot bigger load than any wire can take for long. I watched a wire in an alternator control circuit burn up when it finally shorted to ground after 32 years in service with a police department. The whole wire burned within 2 seconds since generator and alternator control systems aren't short protected circuits. A person can weld with a 100-amp generator. A battery can store a lot of current too.
