What is the primary role of the main fuse box?

The primary role of the main fuse box is to distribute power to various electrical circuits within a vehicle. It serves as a centralized component that houses multiple fuses, each of which provides overcurrent protection to different electrical systems and components, such as lighting, infotainment, and engine management systems. By ensuring that electrical circuits are properly fused, the main fuse box helps prevent damage caused by electrical faults, such as short circuits or overloaded circuits. This critical function not only protects the vehicle's electrical infrastructure but also contributes to the overall safety and reliability of the vehicle's electrical systems.
