Cable Handling and Bend Radius
Provide proper strain relief by adhering to the following guidelines:
For copper cable, the temporary 90-degree bend can never be more than 0.5
inches tighter than the values listed above for any assembly. This is the absolute
minimum sustained bend radius for each cable AWG size. This measurement is
the distance from the switch panel to the point where the cable makes a
90-degree bend. In other words, this number includes the distance from the
connector stand-off from the panel surface.
