Which choice is NOT an acceptable location for the disconnecting means?

• A. Inside the building
• B. Outside the building
• C. Where the conductor passes through the building
• D. In a location that is unrelated to the building

Answer: (D)

Disconnecting means for limited-energy systems must be readily accessible on the premises so power can be shut off quickly in an emergency. It can be located inside the building or outside, as long as it’s easily reachable. Even a location where the conductor passes through the building can be acceptable, provided it remains readily accessible and on the same property. The key problem is placing the disconnect somewhere unrelated to the building; that would make it impractical to reach or operate when needed and wouldn’t meet accessibility requirements. So the not-acceptable option is a location unrelated to the building.
