What is the Restricted Approach Boundary for a 69kV system?

The Restricted Approach Boundary is a defined distance from exposed energized parts, within which special precautions must be taken to avoid electrical shock or injury. For a 69 kV system, the established distance for the Restricted Approach Boundary is 3 feet 6 inches. This distance is critical for ensuring safety while working near high-voltage equipment, as it helps to minimize the risk of accidental contact with energized components.

Understanding these boundaries is essential for any personnel working in proximity to electrical systems, as they are designed based on the voltage level and the associated risks. In this case, the 69 kV voltage level dictates the appropriate proximity limits to maintain a safe working environment.
