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 ?

60s 1/044 for sure

.044" which is 44 thousandths of an inch diameter.

Used 1/044 for lighting circuit, along with 3/029

missed the decimal point 1/.044 but the most sparkes of a certain age would know what I meant, wouldn't they?

The csa in inches then around 0.0015.

Is it your pedantic period Westy as per Tel's

 

[westward10]

No 1/.044 is the conductor diameter not the csa which is around 0.0015 which is around 1.0mm csa.

And where does that fair on the 'butch' scale of conductors, huh?

Does this handy guide help at all?

Thanks all for your replies !

Handling it, I'd say it's less than 1mm2. So maybe it's one strand of some 3x0.029" ? Just off the try to work out what that is in EUville

About 0.50mm

 

[Wilko]

If it is 0.029, I make that to be 0.737mm diameter and 0.427mm2 for each strand, or 1.28mm2 for 3 strands (?)

 

[westward10]

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?

 

[westward10]

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

 

[Wilko]

Ok, now the fun part - what fuse would this perform like ?
Edit - just W10 reply
