In a 230kV area, what distance must be adhered to by unqualified personnel?

In a 230kV area, the requirement for maintaining a specific distance from high voltage equipment is critical for ensuring the safety of unqualified personnel. The correct distance of 13 feet is established as a safety measure to minimize the risk of electric shock or other hazards associated with high-voltage electrical installations. This distance is based on industry standards and regulations that recognize the potential for electrical arcing and other dangers that can occur at these voltage levels.

By maintaining this 13-foot boundary, unqualified personnel are protected from the hazards posed by electrical equipment, ensuring that they do not inadvertently enter areas where they could be exposed to high voltage or dangerous electrical conditions. This safety distance is part of broader protective measures, including the use of proper signage and barriers to limit access to high-risk areas.

The other distances provided do not align with the established safety standards for unqualified individuals near 230kV systems, which highlights the importance of following specific guidelines to safeguard against electrical hazards.
