What is the maximum distance from which a disconnecting means for hermetic equipment must be visible?

The maximum distance from which a disconnecting means for hermetic equipment must be visible is specified as "within sight and 3 meters." This requirement is based on safety standards to ensure that any person operating the equipment can easily see the disconnecting means in case of an emergency or while conducting maintenance.

Being within sight means that the disconnect must be located at a distance where it can be easily observed without obstruction. The specific distance of 3 meters helps to provide a reasonable range for visibility while considering various factors such as the layout of installations and the potential need for quick access to the disconnect in emergency situations. This regulation ensures that operators can safely disconnect the equipment without needing to rely on multiple observations or movements away from their immediate area, thus enhancing workplace safety and operational efficiency.
