Bluesman the power cord for the machine sometimes is less since the distance is very short (resistance per foot). As stated above (SicFabs), its the long run that will drop the voltage which ups the current required for the chosen power which fries the electronics. The ratings look at resistance per foot which will not only drop the voltage, but will produce heat per foot and the resistance goes up with temperature so it can hit a point and result in thermal run away. So at some power level the wire will become hot and melt the insulation. Melted insulation typically results in sparks
