When operating near high-voltage powerlines rated at 33 kV, what clearance is required?

When operating near high-voltage powerlines rated at 33 kV, what clearance is required?

• A. 5 feet
• B. 10 feet
• C. 15 feet
• D. 20 feet

Answer: (B)

Keep a safe minimum distance from overhead lines so you don’t create an arc or contact energized conductors as equipment moves. The distance you need depends on the line’s voltage. For a 33 kV line, you follow the standard minimum approach for medium-voltage lines, which is a ten-foot clearance. This spacing accounts for sag, wind, and any movement of rigging or gear, reducing the risk of arcing or contact. Clearances smaller than this increase the hazard, while larger clearances aren’t required by standard practice for this voltage.
