What describes the service conductors in an underground system?

The description of service conductors in an underground system is accurately captured by the definition that refers to the conductors extending from the service equipment to the point of connection to the service lateral. This definition emphasizes the part of the electrical system that engages with underground utilities, ensuring the safe and effective transition from the utility service point to the customer’s equipment.

In an underground service, these conductors are generally buried below ground, providing protection from environmental factors and physical damage associated with overhead lines. The service lateral refers to the section of wiring that runs from the power company's distribution system to the connection point at the building, thus being a critical aspect of incoming power supply.

Other definitions might describe different components of the electrical distribution system, such as the connection between a street main and the service entrance, which focuses on a different part of the system. Overhead conductors would not apply to an underground system at all. Lastly, incoming conductors from a solidly grounded system don't specifically define the nature of service conductors in this context, thereby making them less accurate in describing the appropriate conductors used in an underground setup.
