Automotive fuses are a class of fuses used to protect the wiring and electrical equipment for vehicles. They are generally rated for circuits no higher than 32 volts direct current, but some types are rated for 42-volt electrical systems. They are occasionally used in non-automotive electrical products. Automotive fuses are typically housed inside one or more fuse boxes (also called an integrated power module (IPM)) within the vehicle, typically on one side of the engine compartment and/or under the dash near the steering wheel. Some fuses or circuit breakers may nonetheless be placed elsewhere, such as near the cabin fan or air bag controller. They also exist as circuit breakers that are resettable using a switch.[1]

There may be a fuse for ignition off draw (IOD), which controls the drawing of electric current in a vehicle while it is shut off; removing this fuse while the vehicle is shut off for more than a few weeks will prevent excessive depletion of the battery.[citation needed]
