What is the correct NCCCO-style exam answer for a question about power line clearance?
NCCCO requires 10 feet minimum clearance from energized power lines up to 50kV, with additional distance for higher voltages and longer booms.
NCCCO certification exams typically test power line clearance requirements based on OSHA 1926.1408 standards. The minimum clearance is 10 feet for power lines rated 50kV or below. For lines above 50kV, add 4 inches for every 10kV increment. These distances apply to any part of the crane or load.
Remember: "Ten Feet Free" - 10 feet minimum clearance from power lines up to 50kV, more for higher voltage/longer boom
