What is the minimum clearance for surface-mounted incandescent or LED luminaires in a closet?

The requirement for minimum clearance for surface-mounted incandescent or LED luminaires in a closet is established to ensure safety and reduce fire hazards. In accordance with the National Electrical Code (NEC), specifically Article 410, the minimum clearance from the luminaire to the nearest point of storage is set to prevent overheating the items stored in closets, which could create a fire risk.

The correct answer reflects the NEC's stipulation that this clearance should be at least 12 inches from the nearest point of storage. This is particularly important in closet spaces where items such as clothing, paper, or other combustible materials might be present. Maintaining this distance helps to mitigate the risk of ignition and allows for the safe operation of the lighting fixtures without posing a danger to the stored items. Consequently, the guideline is a critical aspect of both electrical safety and fire prevention in residential and commercial settings.
