Which statement is true regarding service conductors and building openings?

• A. They may be installed beneath openings
• B. They must be installed at grade level
• C. They shall not be installed beneath openings and shall not obstruct entrances
• D. They must pass through the openings

Answer: (C)

The main idea here is to place service conductors so they aren’t exposed to damage and don’t get in the way of people entering or leaving the building. Service conductors should be located in a way that keeps them protected from physical damage and accessible for service, while not interfering with entrances or blocked pathways. The true statement says they shall not be installed beneath openings and shall not obstruct entrances. Installing conductors under doors, windows, or other openings exposes them to impact from doors or weather and can create a hazard or impede egress. It also makes maintenance and inspection more difficult. Similarly, routing them through openings or directly through entrances would contradict the goal of safe, accessible installation. The other options imply placements that either expose the conductors to damage or impose unnecessary or impractical requirements (like being at grade level or passing through openings), which do not align with safe, code-compliant routing for service conductors.
