For non-qualified employees working near voltages above 50 kV, what distance rule applies?

Explanation:
The rule for non-qualified workers near energized parts above 50 kV uses a voltage-based clearance to reduce the risk of electric shock and arcing. Start with a baseline of 10 feet, then add 4 inches for every 10 kV over 50 kV. This scales the distance with voltage, providing more protection as voltage increases. For example, at 60 kV the distance is 10 feet 4 inches; at 100 kV it becomes 11 feet 8 inches. The fixed distances (3 feet, 6 feet, 12 feet) don’t account for how arcing and shock risk grow with voltage, so they aren’t appropriate for voltages above 50 kV.
