Why must overcurrent protection devices be accessible?

Overcurrent protection devices must be accessible to allow for manual disconnection and maintenance. This accessibility is crucial for safe operation, as it enables electricians or maintenance personnel to quickly disconnect power to a circuit during repair or maintenance work, ensuring that they can work safely without the risk of electrical shock. Furthermore, in emergencies, having easy access to these devices allows for rapid shutoff to prevent further damage or hazards. Regular maintenance and checks on these devices are essential to ensure they function correctly when needed, and accessibility plays a key role in facilitating this process.
