What is the advantage of having covers that require tools to open for handhole enclosures?

The advantage of having covers that require tools to open for handhole enclosures primarily lies in enhancing safety and security. These types of covers are designed to deter unauthorized access and protect the contents inside the enclosure from tampering or accidental exposure. By requiring tools to open, these covers help prevent accidental contact with electrical components or wiring, reducing the risk of electrical shocks or other hazards. Additionally, this feature provides a level of security against theft or vandalism, ensuring that critical infrastructure remains safe and operational.

While it's true that accessibility could be compromised with tool-required covers, this design philosophy prioritizes the protection of personnel and equipment, which is a critical aspect of electrical safety protocols outlined in the NEC. Other benefits like reducing maintenance needs or improving appearance might be relevant but are secondary to the primary focus of enhancing safety and securing the enclosure from unauthorized interaction.
