I left a plug fuse in my jacket pocket, which I then washed

For the price of a fuse I would not risk it, since its
impossible
to say
how it would perform under fault conditions. Any moisture
inside
would
convert to steam on a high current fault, and make the

likely to rupture.

Thanks. Seriously, that was my plan but I just wondered out
of
curiosity.

It would need to be dried out, eg in an oven at a bit above
100C.
Trouble is you'd be hard pressed to tell when it was dry.

The normal way to do that is to keep weighing it until the weight
doesnt drop anymore. And you dont need accurate scales for that
either, just a simple beam balance with another of those fuses.

Yes that's true I have a see-saw arrangment I could try that on.
I've just weighed 3 3amp fuses and 3 13 amp fuses and they all
weigh
between 2.36g and 2.44g

I've now placed a 2.41g fuse in some warm water.
I'll report back later today on it's weight.

Well 22 hours later and the fuse weighs 2.41g

How would water get into a fuse I wonder.

I doubt the metal caps are water tight

The ones here seem to be tried a few.
They are also perhaps 10+ years old so not the cheap chinese
stuff you might be buying on ebay.

I actually stole them from work.

I only ever borrow them. They are MK with the BS logo
That's British standard not bull****.

and they would be about 40 years old. Havent
tried to see how water tight they are in a
washing machine hot cycle tho.

Might be worth a try, if you have the time and can be bothered.

I dont hot wash at all anymore. I used to
do hot washes with very greasy overalls
but dont bother with overalls at all anymore
and never need to do any greasy work on
the car like wheel bearings anymore either.

That way you'll know or at leadt have some
idea depending on your sample size.

But with 40 year old fuses that doesn't prove
anything useful about the currently buyable fuses.

and it may be possible to get some
vacuum effect as it cools down in
a washing machine at the end of the
hot wash followed by a cold rinse.

yeah sure with cheap fuses.
I also tried it with a couple of glass
fuses, no sighn of water getting in.

But did you try it in a washing machine hot wash full cycle ?

No.
I'll leave that to you. what do yuo call hot 60C or 90C ?

Not sure what my current machine does hot wash temp wise.

I no longer use the one I used to do the greasy overalls in.
