Run capacitors are typically wired in series with the run winding of an electric motor. This setup is crucial because the run capacitor helps improve the motor's efficiency and performance during operation.

When a run capacitor is used in series with the run winding, it creates a phase shift in the voltage, allowing for an increase in torque and better utilization of the motor's electrical input. This arrangement is especially important in applications where the motor needs to maintain a consistent speed and operate at or near its rated load.

Other configurations, such as wiring the run capacitor in parallel with the start winding, do not effectively leverage the benefits of the capacitor during continuous operation. Similarly, wiring it directly to the power supply would not allow the capacitor to fulfill its purpose in aiding motor performance while operating under load. Each of these alternatives would result in a loss of the efficiency gains expected from proper capacitor use in electric motor applications.
