The requirement for the ampacity of conductors connecting a capacitor to motor circuit conductors is governed by ensuring that the conductors can safely handle the required current without overheating or causing circuit issues. The correct formula states that the ampacity of the motor circuit conductors should not exceed three times the ampacity of the capacitor conductors.

This relationship ensures that, in the event of high demand during operation, the motor circuit conductors can draw sufficient current while maintaining safety and efficiency. If the motor's ampacity were to exceed this ratio significantly, it could lead to potential overloads in the capacitor conductors, potentially causing damage or failure in the system.

By enforcing this ratio, the design ensures a robust connection that prevents the possibility of excessive current flowing through the capacitor conductors which could lead to their overheating or other failures.
