Which of the following best describes service-drop conductors?

• A. Conductors between the utility's distribution system and the service equipment
• B. Conductors between the meter and the service equipment
• C. Conductors between the main panel and subpanel
• D. Conductors between the service equipment and outlets

Answer: (A)

Service-drop conductors are the lines that run from the utility’s distribution system to the building’s service equipment, typically arriving at the meter or service disconnect outside the structure. They are usually owned and installed by the utility and represent the supply side of the service. This distinguishes them from inside-the-building conductors (service-entrance conductors) that run from the meter to the main panel, from feeders that connect the main panel to a subpanel, and from branch circuits that go to outlets. So the description “conductors between the utility’s distribution system and the service equipment” is the best match.
