Understood that the wire insulation type might be covered by safety standards, but as to wire gauge and ampacity, what issue is there besides potential drop down the cable and short circuit current? The short circuit current wouldn't be much greater than rated current for any length of time, because the source is the power supply, not the ac mains. Ken Javor
