What do the different colored wires represent? Today, Xiaobian is here to explain everything in detail!
Understanding wire color codes is essential for anyone working with electrical systems. Different colors are used to identify the function of each wire in a circuit. Here's a breakdown of what each color typically stands for:
1. **Black** – Used for internal wiring in devices and equipment. It’s commonly used as a general-purpose wire.
2. **Brown** – Represents the positive pole in DC circuits.
3. **Red** – Often used for Phase C in three-phase systems. It can also be the collector in transistors or the cathode in diodes, rectifiers, and thyristors.
4. **Yellow** – Indicates Phase A in three-phase systems. It can also be the base of a transistor or the control terminal of a thyristor or triac.
5. **Green** – Refers to Phase B in three-phase circuits.
6. **Blue** – Typically represents the negative pole in DC circuits. It can also be the emitter in transistors or the anode in diodes, rectifiers, and thyristors.
7. **Light Blue** – Usually denotes the neutral or grounded neutral line in three-phase systems or the grounding neutral in DC circuits.
8. **White** – Commonly used as the main electrode in bidirectional thyristors. It may also be used in semiconductor circuits without specific color coding.
9. **Yellow and Green Striped** – This combination is used for safety ground wires. The alternating pattern ensures clear identification.
10. **Red and Black (Parallel)** – These colors are often used together in AC circuits that use double-core or stranded wires.
When selecting wire colors based on the circuit, it's important to follow standard guidelines:
- In **AC three-phase circuits**, Phase A is yellow, Phase B is green, and Phase C is red. The neutral or grounded neutral is light blue, and the safety ground is yellow and green.
- For **AC circuits using double-core or stranded wires**, red and black are commonly used in parallel.
- In **DC circuits**, brown is used for the positive pole, blue for the negative pole, and light blue for the grounding neutral.
- In **semiconductor circuits**, the collector is red, the base is yellow, and the emitter is blue. The anode of a diode or thyristor is blue, while the cathode is red. The control terminal of a thyristor is yellow, and the main electrode of a bidirectional thyristor is white.
- Internal wiring in devices is usually black, while semiconductor circuits often use white. If confusion arises, other colors like orange, purple, gray, or pink may be used.
- When multiple colors are present on a single wire, the color should be chosen based on the function it needs to represent in the circuit.
By understanding these color codes, you can ensure safer and more efficient electrical work. Whether you're installing new wiring or troubleshooting an existing system, knowing what each color means is crucial. Always refer to local standards and manufacturer guidelines to confirm the correct usage for your specific application.
