What is the term for the conductors and equipment delivering electric energy from the utility to the premise's wiring system?

The term that refers to the conductors and equipment delivering electric energy from the utility to the premise's wiring system is "Service." In the context of the National Electrical Code (NEC), "Service" specifically encompasses all the necessary components that bring power from the utility supply into the building, including overhead or underground conductors, service entrance equipment, and the main disconnecting means.

Understanding the concept of "Service" is crucial as it establishes the boundary between the utility's infrastructure and the electrical installation within a structure. This term is fundamental in the NEC because it sets regulations for the safe installation and maintenance of systems that connect to the electrical grid. The other terms listed do not accurately encapsulate the comprehensive definition and regulatory implications associated with the electrical service entering a premises. For instance, "Power Delivery" and "Energy Distribution" may refer to broader electrical concepts but do not specifically address the physical and regulatory aspects of the service connection. "Utility Connection" is a less formalized term that does not align with the technical definitions used in electrical codes.
