Is it safe to replace a T2 glass fuse with a standard 1 amp fuse till i can get to a merchants or maplins tomorow?

TIA Dave

All depends on what it is for

Its the internal fuse on my CH boiler seems to be working fine just the Mrs wanted me to check

Right

Well if the boiler usually works on a 1 amp fuse, albeit of a glass type, (I do not know the wattage of it) then it should be fine

T2 printed on the fuse, suggests its a 2amp to me
Glass fuses are usually fast blow fuses....
Standard ceramic fuses are slower blowing.....a 1amp ceramic may take upto 2amps before it blows .

As long as the voltage ratings of the fuses are the same or the ceramic one higher, then as Lizzie says it should be ok until it can be replaced with the correct type

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 find when a fuse blows it's much better to fit a much bigger one. They don't usually blow then.

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....

That was my thinking lizzie will replace it tomorrow with a proper glass fuse of the correct rating/ Fuse blew because i'm a knob and turned the wrong fuse spare off Was just rerouting an external time clock

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!

nope .. all capsule fuses ... but 90% of circuits were circuit breaker proteceted. Fuses only used where faster response needed, mainly low power instrumentation and electronic "boxes" ..

The silver foil from cigarette boxes no longer works. Cheapskates have stopped using metal in it. So...it's a 2" nail for me.
