Which statement about primary cables locations is correct?

• A. Primary cables are located only in underground ducts
• B. Primary cables are located only in overhead lines
• C. Primary cables are located in manholes, substations, transformer vaults, or overhead
• D. Primary cables are located only inside customer premises

Answer: (C)

Primary cables carry high voltage and can run in several parts of the distribution network. They are found in underground ducts and manholes, inside substations, in transformer vaults, and on overhead lines. This mix of locations reflects how the utility routes and protects high-voltage circuits to connect generation, transformers, and distribution points while allowing access for maintenance. They aren’t restricted to one place, and they aren’t typically located inside customer premises. Inside customer buildings you’ll usually find service conductors and equipment on the customer side of the point where the utility’s wiring ends.
