Cable Sizes

The cable of the motor is to be sized based on the motor full load current and other factors – it doesn't matter whether the motor is direct starting or other type of starting. Even you use other type of starting, select the cable considering it is direct starting (however, for VFD use, there are some other factors considered for cable sizing).

There is no table that specifically says the size of the cable for the capacity of motor. In addition to the motor FLA, there are many other factors that are to be considered for cable selection.
