Description
A 3-wire AC dual capacitor is commonly used in HVAC systems and typically has three terminals designated for specific connections:

Common (C): Connects to the common wire from the power supply, serving as a shared connection point.

Fan (F or FAN): Connects to the fan wire, providing electrical power to the fan motor responsible for air circulation.

Hermetic (H or HERM): Connects to the hermetic compressor wire, supplying power to the hermetic compressor motor that compresses refrigerant and regulates temperature.

Ensure that you follow the manufacturer's specifications and guidelines for the specific dual capacitor you are working with. The capacitor may also have two different capacitance ratings, typically expressed as a dual value (e.g., 35/5 uF), with one value for the hermetic compressor (HERM) and the other for the fan (FAN). Always prioritize safety by disconnecting power before any wiring work.
