Some of the most important electrical components in vehicles are fuse blocks. Fuses and fuse blocks are responsible for providing a layer of protection to homes and vehicles from current overflows and radical temperature changes. Without them, you could find yourself blowing circuits in your house or car just by turning on electronics or operating a vehicle normally.

Power distribution is the main function of a fuse block to prevent voltage spikes and short circuits from damaging wires. It also protects other system parts from receiving damage should something happen during normal operation. Many different kinds of vehicles, including motorcycles and watercraft, have fuse blocks in their engines as part of the system that powers them.

Have you ever asked yourself the question: what exactly is a fuse block? Have you ever bought one for yourself, or even know what it can be used for? Continue reading our fuse block guide and to learn about fuse block uses!

What Is a Fuse Block and Fuse Box?

A fuse block and fuse box have multiple fuse circuits to help distribute power. For vehicles, this keeps an operating vehicle from short-circuiting or damaging any parts within an engine if there’s a spike in power. They contain fuses of different amperage values and help protect against any sudden spike or short.

Fuse boxes are similar but are used primarily in homes. They contain around six to twelve fuses and are usually found in residential homes. Both have similar functions, but with different applications.

How Are Fuse Blocks Used?

Most fuse blocks are located within the dashboard of a standard vehicle, with some having it placed within the engine compartment. It is designed to be used for the entirety of a vehicle’s lifespan but can get replaced for any number of reasons.

Automotive fuse blocks have fuses that range anywhere from 15 to 30 amps. The fuses are made to blow or burn out before damage is done to any parts within the vehicle. You can replace a fuse that is damaged with another of similar amperage and continue driving as normal. 

Fuse Block Tips to Remember

There are a few helpful things to keep in mind in order to keep a fuse block in peak condition. Keeping it free of debris and dry is important, as well as allowing air to flow freely around it. This can help prevent heat from building up and damaging the fuse block or fuses inside.

While a fuse block doesn’t need routine maintenance of any kind, it is a good idea to check it occasionally.  Looking for any fuses that might be loose or need replacing will keep things working well and prevent larger issues that could occur later. It’s also smart to be wary of any corrosion that might be visible on the contacts of the fuses, which should be replaced as quickly as possible.
