Circuit Breaker Switch Colors

By | March 7, 2023



In the world of electrical circuits, it is important to understand the different colors that are associated with circuit breakers. Circuit breaker switches come in a variety of colors, and each one has a specific purpose. Understanding these color codes can help you ensure that your electrical system is safe and efficient.

The most common color of circuit breaker switch is black. This color is used for the main circuit breakers, which provide power to the entire electrical system. These switches are typically rated for 15 to 20 amps and are designed to trip when the current exceeds the rating. This helps to protect the wiring from damage due to an overload.

Red is another common color used for circuit breakers. This color is used for branch circuit breakers, which provide power to individual circuits within the system. These switches are typically rated for 15 to 20 amps and are designed to trip when the current exceeds the rating. This helps to protect the wiring from damage due to an overload.

Finally, yellow is the color used for arc-fault circuit interrupters, which are designed to detect and prevent fires caused by arcing electricity. These switches are typically rated for 20 amps and are designed to trip when arcing is detected. This helps to protect the wiring from short circuiting and potential fire hazards.

When installing or troubleshooting an electrical system, knowing the different circuit breaker switch colors is a must. It is important to properly label each switch so that you know its purpose and can quickly identify it if you encounter a problem. Knowing the different circuit breaker switch colors can help you keep your electrical system safe and running smoothly.
