Load Wiring
When connecting load wiring to the power supply, consider the following factors:
•
Current carrying capacity of the wire
•
Maximum load wiring length for operation with sense lines
•
Noise and impedance effects of the load lines
Current
Carrying
Capacity
As a minimum, load wiring must have a constant capacity greater than the output
current rating of the power supply. This ensures that the wiring will not be damaged
even if the load is shorted.
Table 2.3 . shows the maximum current rating, based on
450A per square centimeter, for various gauges of wire rated for 105°C operation.
Operating at the maximum current rating results in a temperature rise of
approximately 30°C 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 higher temperature-rated wiring. For high current applications,
custom-designed bus bars are typically used. To increase the current carrying
capability, use parallel cables.
