Shouldn't you be wondering why the fuse blew in the first place? Power surge or something that's going to cook you all in the middle of the night?

Its OK steve i know why the fuse blew in the first place but thanks for your heartfelt concern

In anycase a fault would blow a 1 amp fuse very quickly, and if you have a fully RCCB / MCB protected consumer unit that will cut power as well.

If you know what blew the fuse to start with that is ok, but I am fed up of telling my friends that they must never just replace a fuse without knowing why it was knocked out!  There is always a reason.

I spent 37 years working a different philosophy ...    We ALWAYS changed a blown fuse ONCE. If it blew again then full fault finding commenced. If it carried on working it was accepted.

Fuses "tire" as they heat and cool every power cycle, plus the environment was fairly harsh ... high cycle times, high vibration, fairly extreme temperature ranges....

My God Entwood, you are back in porcelain and wire fuses territory!!

With modern fuses I find them very reliable, and only one has blown for me over the last 10 years.  That was on a steam iron that was faulty with an element blown!

Very similar to a glass fuse 
Its the material that surrounds the fuse wire that will determines how quickly it will blow
Incidently, the rating of the fuse, is the max current that can pass through it ie.. a 1amp fuse will not blow if 1amp passes through it.

.................or a fault develops in the appliance and shorts the circuits.


In both cases the fuse protects the cable, not the appliance
