Service conductors are defined as?

• A. The conductors from the service point to the disconnecting means
• B. The conductors from the main breaker to outlets
• C. The conductors from the transformer to the meter
• D. The conductors inside the service panel

Answer: (A)

Service conductors are the wiring that brings power from the utility into the building, running from the point where the utility’s supply connects to the building’s wiring up to the main switching device that can disconnect the entire installation. This path defines the boundary between the utility side and the building side of the electrical system, ending at the service disconnecting means. That’s why the description “from the service point to the disconnecting means” matches exactly. The other options describe different parts of the system: conductors inside the panel or between outlets are branch circuits or panel wiring, not the incoming service conductors; the path from the transformer to the meter is upstream utility equipment, not the building’s service conductors.
