What are service conductors, overhead?

Service conductors, overhead, refer specifically to the overhead wires that are run from the service point—typically where the utility's distribution system connects to a customer's premises—up to the first point of connection, which is usually the service entrance of a building or structure. This definition is crucial because it emphasizes the role these conductors play in supplying electrical power from the utility provider directly to the consumer's electrical system.

These conductors are designed to withstand environmental conditions and are installed in a manner that ensures safety and reliability in the transmission of electricity. Their placement overhead is also a significant aspect, as it helps to avoid potential damage that could occur if they were installed underground, where they would be more susceptible to water infiltration and other underground hazards.

The other options do not accurately describe overhead service conductors. For instance, conductors located underground would not be classified as overhead. Additionally, cables that connect to solar panels do not pertain to the general definition of service conductors in a utility context. Lastly, the wires that connect electrical devices to a ground source refer to grounding conductors, which serve a completely different purpose related to safety and electrical fault protection. Thus, option B captures the specific nature and function of overhead service conductors accurately.
