What are the mandated electrical exclusion zones around power poles and transmission towers?

• A. Poles: 6.4 meters, 3 meters with ESV spotter; Towers: 10 meters, 8 meters with ESV spotter
• B. Poles: 5 meters, 2 meters with ESV spotter; Towers: 9 meters, 7 meters with ESV spotter
• C. Poles: 7 meters, 4 meters with ESV spotter; Towers: 11 meters, 9 meters with ESV spotter
• D. Poles: 6.0 meters, 3 meters with ESV spotter; Towers: 9 meters, 7 meters with ESV spotter

Answer: (A)

Electrical exclusion zones are the safe boundaries set to keep people away from energized parts on poles and towers. There are two levels: a larger outer exclusion zone and a tighter inner zone that may be entered only when an Electrical Spotter Vehicle (ESV) is present to guide operations. For power poles, the outer boundary is 6.4 meters, with a closer inner boundary of 3 meters if an ESV spotter is on site. For transmission towers, the outer boundary is 10 meters, and the inner boundary is 8 meters when an ESV spotter is used. This arrangement explains why the option with these distances is correct: towers require a larger outer buffer than poles due to higher voltage and risk, and the inner distances are reduced only with ESV spotter supervision.
