About Car Fuse Box

Cars have various electrical components that require a fuse to protect against short circuits. There are two fuse boxes, one located near the engine or under the hood and the other is located near the driver seat.

The car fuse box under the hood protects engine components including engine control unit (ECU), cooling fan, ABS motor and battery. Whereas the fuse box near the dashboard protects cabin components like power windows, interior lights, radio or infotainment system and turn signals.

Let`s delve a bit deeper to understand how car fuse boxes work and what their types are.

A car fuse box has a series of different fuses, relays and diodes to protect the electrical circuits from overload or short circuit. The fuse box is powered directly by the battery. The wires from the fuse box connected to the vehicle components that need protection.

The fuses consist of a wire conductor that breaks when the current exceeds the ampere limit. The ampere limit is usually defined on each fuse along with different colour codes. Placing the right fuse with the correct ampere is integral for protection.
