Very recently, I was asked the following question about plug top fuses …
If it says 13 amps on the fuse … then why does it not fuse at 13 amps? Which is true.

So in this video from LearnElectrics we will look at this, explain the reasons for it and answer some other questions like –

Why does a 13 amp plug, or plug top as we call them, overheat?
And a popular question, can a 13 amp fuse REALLY carry 20 amps

And we will also look at the fusing characteristics of a BS1362 fuse and explain how the fusing tables work and how we can quickly and easily interpret the information that they hold. Hopefully, things will be a lot clearer afterwards and a little more knowledge will have been stored in your mental toolbox.

If we can understand the fusing curves of a BS1362 plug top fuse, as shown in this particular video, then we will also understand how the fusing tables work for other fuse types.

Each fuse type will have its own unique requirements, how much current, how much time etc. as defined by the relevant design standards for that fuse. They are all different but have many similarities in how they are laid out and in how to interpret them.
