What role do underground service conductors play in electrical installations?

Underground service conductors play a crucial role in connecting the service point, which is the point of supply from the utility, directly to the service-entrance conductors of a building. This connection is essential because it safely carries electrical power from the utility's infrastructure to the electrical system within the building.

The service point is typically where the utility's responsibility ends and the customer's responsibility begins. By using underground conductors, these installations provide a reliable and often safer method of delivering electricity since they are less susceptible to weather-related disruptions and damage compared to overhead wiring.

Other options may suggest different roles, such as connecting utility poles or distributing power across buildings, but these do not accurately describe the specific and primary function of underground service conductors in residential and commercial installations.
