A basic HVAC voltage wiring setup for a single-phase compressor system, including a contactor, capacitor, and multimeter. The contactor receives 240V input (yellow and blue wires) and distributes power to the compressor and start capacitor. The compressor is connected via three terminals: "Common," "Run," and "Start." The capacitor assists with the initial torque needed to start the compressor motor by connecting to the "Start Winding." A clamp meter is shown reading 240V to verify voltage at th
