I am an European, so I am not sure if that matters.
All I know is that I need a cable with the right amp or wattage throughput capability. Our cables are named as 3x1.5, 3x2.5, 3x3.5 etc, I guess that is 3 cords that are 1.5 cm thick, 2.5 cm thick, etc..
So I have heard the following and wanted to debunk it if its a myth. If let say an appliance of mine uses a 3x1.5 cable which has max 4 KW throughput, do I need a thicker extension cable than the original cable that this appliance use? Or I am good with the same one as long as the capacity of the cable is higher than the appliance itself.
It seems very pointless to me, but it makes me anxious when using random extension cords on higher wattage units like oil radiators and washing machines, as I never find them thicker then the appliance cable itself.
