What is the term for the point of connection between the utility's facilities and the premises wiring?

The term that accurately describes the point of connection between the utility's facilities and the premises wiring is “Service Point.” This term is well-defined in the National Electrical Code (NEC), which outlines that the service point is where the responsibility of the utility ends, and the responsibility for the premises wiring begins. It is significant as it marks where the service equipment is connected to the utility’s distribution system, often associated with the meter or service disconnect.

Understanding this distinction is crucial for compliance with electrical codes and standards, ensuring safe and reliable electrical service. The service point is also important for determining issues related to service voltage, grounding requirements, and potential fault conditions. This precise terminology helps electricians, engineers, and inspectors communicate clearly about electrical installations and maintenance responsibilities.
