In general, capacitor wires are designated by three colors: red for the power source’s positive side, yellow for controlling the fan motor’s speed, and white for the neutral side of the power source, which connects to the ground. How do you connect wires to a capacitor?
The color code of wires in the diagram corresponds to the color code of the wires on the actual capacitor. For example, a black wire in the diagram would indicate the “C” (common) terminal, a brown wire would indicate the “FAN” terminal, and a red wire would indicate the “HERM” (compressor) terminal. A yellow wire would indicate the “COM” terminal.
In conclusion, the electric motor capacitor wiring diagram is a valuable guide for connecting the capacitor to the motor and power supply. It provides instructions on which terminals to connect and identifies the wire colors for each terminal. Following the diagram accurately ensures a safe and efficient motor operation.
The AC capacitor wiring diagram explains all the terminals in the capacitor along with their wires connecting the capacitor to a fan motor, power supply, compressor, and other loads. The color code of wires in the diagram corresponds to the color code of the wires on the actual capacitor.
· Red: Typically used for the start winding (Herm terminal). · Brown: Commonly connected to the fan motor in HVAC systems (Fan terminal). · Yellow/Blue: Often connected to the compressor or common terminal (C). · White: Generally used as a neutral or common wire, completing the circuit. The most common color codes for AC capacitor terminals are:
Yes, you can replace a capacitor even if the wiring colors are different, as long as you match the terminals correctly (C, F, H). Always double-check the labels on both the old and new capacitors to ensure proper connections.
