What must always be labeled on the circuit breakers within a service panel?

• A. The brand of the circuit breaker
• B. The circuits they control
• C. The voltage rating
• D. The amperage capacity

Answer: (B)

The necessity of labeling the circuits controlled by circuit breakers in a service panel is crucial for safety and proper function in any electrical system. This labeling provides essential information that enables easy identification of which circuit breaker corresponds to which area, appliance, or room in a building. This practice not only facilitates maintenance and troubleshooting but also ensures that in emergencies, such as a fire or an electrical fault, responders can quickly locate and turn off the relevant circuits, minimizing risks. Moreover, proper labeling helps prevent accidental overloads. When a user knows which breakers control specific circuits, they can avoid turning off power to critical areas inadvertently. Labeling the brand of the circuit breaker, the voltage rating, or the amperage capacity, while useful for ensuring compatibility and safety, does not provide the immediate operational clarity needed for effective electrical management and safety in day-to-day use. Thus, focusing on labeling the circuits they control is a vital practice that enhances understanding and safety in electrical systems.
