What is the safe approach distance to a 12,000-volt line phase-to-phase?

The safe approach distance to a 12,000-volt line phase-to-phase is 2 feet 2 inches. This distance is critical for ensuring the safety of workers who may be working near high-voltage lines. The established approach distance takes into account the potential for electric field effects and flashover, which can occur even without direct contact if a person approaches too closely to energized lines, especially those at high voltage.

Adhering to this safe approach distance helps mitigate the risk of electric shock or inadvertent contact that could lead to serious injury or fatality. It is important that workers understand these distances and follow safety protocols to maintain a safe working environment when dealing with electrical installations and maintenance near power lines.
