The Main Circuit Breaker is supposed to protect the wiring from a shorted battery. If the regulator is connected directly to the battery (as shown on the diagrams), not utilizing the main circuit breaker for protection, there is a potentially dangerous situation. If the regulator internally or externally shorts that wire, connected to the battery, to ground, the battery will supply upto 200 amps of current, **__causing the wire to overheat and possibly creating a fire__**. This is what the Main Circuit breaker is to prevent. | The Main Circuit Breaker is supposed to protect the wiring from a shorted battery.
