Branch-circuit overcurrent devices in emergency circuits shall be accessible to ______ only.

Branch-circuit overcurrent devices in emergency circuits are designed to be accessible only to authorized persons. This requirement is critical for several reasons.

Firstly, authorized persons are typically trained and knowledgeable individuals who understand the specific functions and operations of emergency circuits. They are familiar with safety protocols and can effectively respond to any issues that may arise, ensuring that the circuits can be accessed and managed safely.

Secondly, limiting access to authorized persons minimizes the risk of accidental interruptions or mishandling of the emergency systems. Emergency circuits are crucial for maintaining safety and functionality during emergencies, and only trained individuals should interact with these systems to prevent unintended consequences.

Overall, this provision ensures that emergency circuits can be maintained and operated safely and effectively, reducing the risk of hazards that could occur from unauthorized or untrained individuals accessing these critical components.
