What causes a fuse to blow and what to do when they do!

How a Fuse Blows

Fuses are made from metals like tin and alloy both have a low melting point the lower the melting point the less current the fuse can take. The fuse blows when the centre gives way due to a surge of power flowing through and the core can’t handle it and it melts.

5 Most Common Reasons For A Blown Fuse

So why does a fuse blow?

1. Electrical systems and wiring are incongruent.

The electrical wiring and systems used in buildings today are a far cry from the ones used many years ago.

The wiring in new houses is generally far superior to old wiring systems. Present day systems require a lot more power than older houses were designed for. The wiring in old houses tends not to be able to withstand the demands of modern society. Resulting in blown fuses and switchboards.

2. Many appliances actually require more amperage than fuses can maintain.

When multiple appliances are switched on simultaneously it prevents electricity from flowing smoothly and creates pockets. Many appliances have to fail safes and then issue either blows fuses in appliances, switchboards or service fuses.

3. Electrical Surpluses Occur In Succession. Electrical Surges and Surpluses

When electrical surges occur in succession weaker filaments in the fuse occur resulting in blown fuses.

4. Electric Short Circuits

A short circuit is when a live wire contacts ground. This is a potentially dangerous situation resulting in a blown fuse. This is designed to protect you.

5. Fuse Blow Naturally

Fuses just blow over time. A lot of times you just have to replace the fuse and your good to go.

6. Incorrect Fuses Fitted.

If an incorrect fuse has been fitted it will result in frequently blown fuses.
