Which term describes a document that acknowledges that a section of the Catenary or Third Rail may be de-energized and communicates this to prevent entry into the de-energized area?

• A. Power Director
• B. Plate Order
• C. Qualified Person
• D. Rail Return

Answer: (B)

When working around energized overhead or third-rail sections, you need a formal way to show that a specific area is de-energized and to warn everyone to stay out. The document that does this is a Plate Order. It identifies the exact section (the plate) that is de-energized, sets the time window for that condition, and names who authorized and oversees it. This written notice ensures that all personnel, control centers, and maintenance crews have a clear, shared understanding of the de-energized area and won't inadvertently enter it, which is crucial to preventing electrical injuries.

Power Director refers to a person, not a document. A Qualified Person is a role—someone trained and authorized—not the form used to communicate the de-energized status. Rail Return is a circuit/grounding concept, not a communication document.
