[SML] Safety tip.

[Mt. Angel Performing Arts Center]

I am not a metallurgist but (unlike a cartridge fuse element) the 
calculation would also (IMO) depend on the physical load applied to the 
cable at the time the current is passing through it.

As the electrical current heats the cable it will soften and become 
elastic, thereby stretching and reducing its cross-sectional area and 
increasing the current density.

So once it starts stretching the failure will accelerate exponentially.

Failure is not an option. It comes bundled with your software.
