According to the National Electrical Safety Code (NESC), drop cables must be placed at a minimum depth of how many inches?

The National Electrical Safety Code (NESC) specifies guidelines to ensure safety and minimize hazards related to electrical infrastructure. In the context of drop cables, which are often used to connect overhead distribution lines to customers' premises, it's important to adhere to specific depth requirements to protect these cables from environmental factors and physical damage.

The correct minimum depth for placing drop cables is 18 inches. This requirement helps to ensure that the cables are well-protected from potential disturbances such as excavation activities, landscaping, or natural erosion. By maintaining a depth of at least 18 inches, the likelihood of accidental contact or damage to the cables is significantly reduced, thereby enhancing safety for both workers and the public.

This depth requirement is established based on practical considerations regarding where typical excavation might occur, ensuring that drop cables are adequately shielded while still being accessible and functional for their intended use.
