For a WEG brand 184T 5hp 1-phase 240V motor, you typically need a start capacitor in the range of 100-200 µF and a run capacitor around 20-50 µF. The specific values can vary based on the motor's design and application, so it's essential to check the motor's nameplate or consult the manufacturer's documentation for precise specifications. Always ensure that the voltage rating of the capacitors meets or exceeds the motor's operating voltage.
