Underground cables operating at over 1,000 volts must meet the depth requirements outlined in which table?

The requirement for the installation depth of underground cables operating at over 1,000 volts is detailed in Table 300.50. This table provides critical information regarding the minimum cover requirements for different types of cables based on their voltage level and the surrounding conditions.

By specifying the depth at which these cables must be buried, Table 300.50 helps ensure the safety and reliability of electrical installations. It takes into consideration various factors such as the type of cable (e.g., conductors, fiber optics) and environmental influences that could affect the cable's performance over time. Adhering to these depth requirements is essential for preventing accidental damage to the cables, which could lead to hazardous situations or power outages.

The other tables mentioned do not encompass the specific depth requirements for cables over 1,000 volts. Each table serves a distinct purpose within the Code, focusing on different aspects or scenarios relevant to electrical installations, but Table 300.50 is the one specifically addressing the depth of underground cables handling high voltage. This distinction is crucial for anyone involved in electrical infrastructure to understand and apply correctly.
