  1. 6 feet
  2. 10 feet ✔
  3. 15 feet

Why: Table A in 1926.1408 sets a 10 foot minimum clearance for lines up to 50 kV. Higher voltages need more room.

Huh, didn't know that: Another allowed option is to keep the crane, load line and load at least 20 feet from the line.

The dad joke
Why did the crane stay 10 feet away? It did not want to spark conversation.
