What is the definition of an inaccessible enclosure in grounding and bonding?

An inaccessible enclosure in the context of grounding and bonding is defined as one that is sealed by the utility. This means that it's an enclosure that cannot be accessed by the typical user for maintenance or connection purposes because the utility company has secured it as part of their infrastructure. Such enclosures often contain vital equipment or systems that require specialized knowledge or permissions to access, ensuring safety and compliance with regulations.

This definition highlights the importance of secure and controlled access to certain electrical components. The nature of being sealed by the utility also implies that these enclosures are designed to provide both safety and security, preventing unauthorized access that could lead to hazards or improper handling of electrical systems.
