100A fuse no longer allowed

[AGT]

We used to use a 1.5multiplier for fuses so a 80 amp fuse would hold 126 amp for 1 hour

Would cooling on the fuse enable it to last at higher amps for a period of time?

Probably because as the fuses get hotter, the electrical resistance increases and therefore increases the amount of power dissipated in the fuse leading to a positive thermal feedback.

I used to do the air cooling trick back in the day of having a 60A fuse.

I have never heard of a fuse blowing.

Best not look at my house, its the wrong side of 150A possible but i would say prob 0%

I appreciate this is silly, but couldn't help chuckling at the irony, if the fan consumption was the straw, that broke the fuses back! Irony overload perhaps?

I assume that water cooling is out of the question?

They can’t just change fuses down automatically, as some people will have paid to have a 100amp fuse….

Not sure how this is recorded in DNO land…
But don’t think the person fitting smart meters will have access to check this?
