Load
As a minimum, load wiring must have a current capacity greater than the output
Conductor current rating of the power supply. This ensures that the wiring will not be damaged
even if the load is shorted.

maximum current rating results in an approximately 30 °C temperature rise for a
wire operating in free air. Where load wiring must operate in areas with elevated
ambient temperatures or bundled with other wiring, use larger gauges or wiring rated
for higher temperatures.
