Where are primary cables located?

• A. In service boxes
• B. Manholes, substations, transformer vaults, or overhead
• C. In customer premises
• D. In underground water pipes

Answer: (B)

Primary cables are the high‑voltage conductors that carry power from substations toward the distribution network. They’re located in the utility’s street and substation infrastructure, such as underground in manholes or transformer vaults, at substations, or on overhead lines. They aren’t routed inside customer buildings or service boxes, and they aren’t placed in underground water pipes, which is why those options don’t fit.
