What requirement does the NEC set for lighting in commercial spaces?

The NEC, or National Electrical Code, emphasizes the importance of providing adequate illumination levels in commercial spaces to ensure safety, functionality, and comfort for occupants. This requirement can typically be found in specific sections that outline the necessary light levels based on the type of space and its intended use. By specifying adequate illumination, the NEC helps to promote environments that reduce the risk of accidents and ensure that tasks can be completed effectively.

In commercial settings, appropriate lighting is vital not only for aesthetic appeal but also for meeting regulatory standards and enhancing productivity. Thus, the focus on adequate illumination levels aligns with the NEC's broader goal of ensuring safe and efficient electrical installations.
