1) AWG = American wire gauge
kcmil = Thousands of circular mils (1 kcmil = 0.5067 mm²)
The "Maximum terminal capacity" specification indicates the maximum pos-
sible sizes that can be connected to the power terminals. The cross-sectional
areas and gauges that should be used for the power supply and motor con-
nections are recommendations for the corresponding frame sizes and ratings
and are provided as examples.
￫
Use the general installation instructions and local conditions as a
basis when selecting terminal capacities.
