having tested that 1.1 metre length of 10 amp rated extension lead to see just what level of current it could pass while remaining within a safe temp limit - it seemed I should adopt the philosophy of Jamie and Adam Mythbuster and test exactly how much current it takes to ** COMPLETELY DESTROY ** the same cable.
With a 50 amp capability on hand, I figured it just had to be tried !!!!
Remember, 24 amps caused the cable to reach its safe rated temperature of
75C.When stepped up to 30 amps, there was still no sign of the cable demising any time soon.
At 34 amps it was getting damn hot - too hot to touch, but still persisted in working OK.
Finally, at a current of 43 amps and a surface temp of about 180C, wisps of smoke appeared and large, ugly bubbles began to grow on the cable like blisters PLUS where I had soldered the blue and brown wire ends together - the solder melted. I decided to call it quits.
The cable now looks very sad and sorry indeed and has a dead short inside it somewhere.
But I can still report that there are no exposed conductors visible.
