What are Fuse Blocks?

Fuse blocks are important electrical components intended to protect a vehicle's electrical

devices from shorts or power surges. The fuse blocks contain fuses rated at different amperage values depending upon the electrical device that it is

protecting. Upon a sudden voltage spike or short, the fuse will burn out, protecting the affected device.

Changing an automotive fuse is a straight-forward operation. Once the appropriate blown fuse has been located, it is pulled from its mounting location

within the fuse block. A new fuse is simply inserted into the vacated location in the fuse block. It is imperative that the same amperage rated fuse is used

when changing any blown fuse.

Automotive fuse blocks use fuses rated from 15 to 30 amps. This rating coincides with a particular electrical component's ability to withstand

damage. The fuse blocks are designed to allow the fuse to blow or burn out before the component can be damaged. Replacing any blown fuse with a fuse of a

higher amperage rating could cause irreparable damage to the vehicle's electrical component.
