Automotive fuses are safety devices used in vehicles to protect electrical circuits from overloads and short circuits. They work by breaking the circuit when the current exceeds a certain level, preventing damage to wiring and components. Fuses come in various types and ratings, designed to handle specific electrical loads in different parts of the vehicle. Typically found in the fuse box, automotive fuses can be easily replaced when blown. Common types include blade fuses, glass tube fuses, and circuit breakers. Understanding the function and location of these fuses is essential for maintaining a vehicle's electrical system and ensuring safe operation.
