What wire is this ? in 20 characters or more

[Wilko]

Hi - working in a house with an original 60s installation and found this little bit of copper wire used as a fuse. It was in place of 30A fuse wire, I think. I've put a bit of 1mm2 for reference in the pic.

Any thoughts on what it is? And what would be its rating as a fuse ?

Yeah I rounded it up but you are correct, the csa in mm for a 3/.029 is 1.29mm

Nothing to do today then Guys?

30A fuse wire has a csa of about 0.56mm I believe.

Ok, now the fun part - what fuse would this perform like ?

A bit over 25A using the csa of 30A and 25A fuse wire diameters.

That's no good, I was hoping for something more testing ...

Wasn't he in that film about being shipwrecked with a Tiger?

I'd hazard a guess and assume the rating is meltdown of equipment rating.
