The minimum approach distance for AMT-2 qualified employees against Catenary, Signal Line, Utility Wires less than 35000 volts for equipment operating near energized or de-energized and not grounded is?

• A. 8 ft.
• B. 3 ft.
• C. 15 ft.
• D. 6 inches.

Answer: (B)

When working near exposed conductors, the distance you must stay away from them is driven by the voltage level and whether you’re qualified to work around live equipment. For AMT-2 qualified employees dealing with catenary, signal lines, or utility wires under 35,000 volts, and when the equipment could be energized and is not grounded, the required minimum approach distance is three feet. This gap helps prevent shock or an arc flash if a tool or part of your body briefly bridges the space or if the conductor shifts. The fact that the line isn’t grounded keeps the path to ground uncertain, so maintaining this clearance reduces the risk of electrical contact or arcing.

Distances like six inches are far too close for these conditions, and much larger distances (such as eight or fifteen feet) aren’t necessary for this voltage range and qualification level—they are used in other scenarios (higher voltages, different grounding or qualification requirements). Keeping three feet as the minimum reduces risk while still allowing work to proceed safely under these specific circumstances.
