What information is required on a service panel label?

The correct answer focuses on the necessity of having information about the maximum amperage rating and a list of the circuits served prominently displayed on a service panel label. This information is essential because it allows anyone working with or around the electrical system to understand the capacity of the panel and which circuits correspond to each breaker. Knowing the maximum amperage rating helps ensure that devices connected to the panel do not exceed its capacity, thereby preventing overloads and potential hazards. Furthermore, a list of the circuits served aids in promptly identifying which circuit to turn off or troubleshoot during maintenance, enhancing safety and efficiency.

Other options may provide useful information but do not address the critical safety and operational requirements mandated for service panels. The color scheme, model and serial number, or installation date, while potentially relevant in other contexts, do not provide the necessary operational data that must be readily available for safe use and maintenance of electrical systems.
