What is the restricted approach boundary for 480 volts AC?

The restricted approach boundary for 480 volts AC is indeed designated as 10 inches. This boundary is critical in maintaining safe working distances to protect personnel from electrical hazards. The restricted approach boundary is the distance within which specific work practices, such as the use of personal protective equipment (PPE) and additional safety measures, are required to prevent accidental contact with energized electrical parts.

In high-voltage environments, maintaining this boundary helps minimize the risk of electrical shock or arc flash, which can have severe consequences. By defining the restricted approach boundary at 10 inches for 480 volts AC, safety regulations ensure that workers maintain an appropriate distance during work activities, thus actively contributing to their safety.

Understanding the significance of this boundary fosters a safety culture among workers and emphasizes the importance of adhering to established electrical safety standards.
