What is a dead-end in distribution circuits?

• A. A point where the conductor splits to multiple feeders.
• B. A switch that always remains closed.
• C. A device that terminates the conductor or forms a boundary point on the distribution line.
• D. A safety ground point.

Answer: (C)

The main idea is termination of the conductor, creating a boundary point on the distribution line. A dead-end is where the line ends or is terminated by a device that anchors and insulates the conductor, marking the endpoint of that feeder. This setup often includes protective equipment—like a fuse or switch—that allows the circuit to be isolated for maintenance or fault protection. That’s why this description fits best: it refers to a device that terminates the conductor or forms the boundary point on the distribution path. It’s not a junction where lines split into multiple feeders, nor a switch that’s always closed, nor a grounding point.
