What is the minimum clear distance for nominal voltage to ground of 0-150 volts?

For a nominal voltage to ground of 0-150 volts, the minimum clear distance is established to ensure safety when working around electrical installations. In this context, clear distance refers to the space required to protect individuals from accidental contact with energized parts or accidental electrical discharges.

The National Electrical Code (NEC) and other safety standards specify these clearances based on voltage levels to mitigate the risk of electric shock. A minimum distance of 3 feet is deemed appropriate for voltage levels in this range. This distance helps to maintain a safe working environment by providing enough space to avoid hazards, especially in settings where people might be moving or working around electrical equipment.

Maintaining this clearance is essential for compliance with safety regulations and to ensure the safety of workers or individuals in the vicinity of electrical installations. The importance of these clearances cannot be overstated, as they are critical in the prevention of accidents and ensuring safe operational practices.
