PVC insulation of an electrical cord with 12.5 Amps current was melted and short circuit was made when the cord is coiled only three times and covered with cloth. The size of this cord was 0.75 mm2 in area.
Short circuit was made not by man but by electricity. As the cord is exposed to high temperature, the insulation fails by becoming soft and flowing off the conductor.
