According to NEC 210.70(A)(3), where must at least one lighting outlet be installed?

The correct answer is based on the requirement set forth in the National Electrical Code (NEC) 210.70(A)(3), which mandates that a lighting outlet must be installed in certain locations for safety and functional purposes. An outlet in the attic is crucial as it allows for adequate illumination when accessing this space for maintenance or inspections, especially since attics can often be dark and difficult to navigate.

The code focuses on ensuring that all areas where people may need to enter or work are well lit to reduce the risk of accidents. While other areas like the basement or garage also typically require lighting outlets, the specific mention in the NEC that pertains to attics highlights the importance of having a reliable source of light in that often-overlooked area. This requirement is aimed at promoting safety and proper access for any electrical work, inspections, or general maintenance that might need to occur in the attic space.
