The statement is false because the wire size for the service drop does not necessarily have to match the wire size for the service entrance conductors. Service drops refer to the overhead or underground conductors that deliver electricity from the utility company to the service entrance of a building, while service entrance conductors are the wires that carry that electricity from the service drop into the main electrical panel of the building.

The size of the service drop is determined by the utility company based on their specifications and the overall demand of the building’s electrical load. In contrast, the service entrance conductors must meet the National Electrical Code (NEC) requirements, which consider the load requirements, the length of the run, and other factors like temperature and insulation type.

This distinction allows for flexibility and optimization in installations, as the service drop may utilize larger conductors to minimize voltage drop, while service entrance conductors can be sized appropriately for the specific electrical demands of the building. Consequently, each installation can be tailored to meet safety and efficiency standards without requiring identical wire sizes for each component.
