I left a plug fuse in my jacket pocket, which I then washed at 40

obviously) or will its electrical properties be compromised?

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 enclosure more
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
doesn’t drop anymore. And you don’t 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.

What scales are you using BTW? I'm looking at Acuweight jewellery
scales.

Shouldn't really matter but ours are scalix 'precision' costing about £30
0-600g and the display reads to two decimal places.
So I'd estimate a precision of aboit + or - .02g

which I think is close enough to prove the point being made.

Mine is two decimal places also. Cost half as much though :-)
