Final answer:
The minimum clearance for an incandescent light in a closet is 12 inches (30.48 cm) from any stored items or the wall of the closet, as per the fire safety code.
Step-by-step explanation:
The minimum clearance for an incandescent light in a closet is determined by the fire safety code. According to the National Fire Protection Association (NFPA), incandescent lights in closets must have a minimum clearance of 12 inches (30.48 cm) from the closest point of the light bulb to any stored items or the wall of the closet. This clearance is necessary to prevent the heat produced by the light bulb from igniting any flammable materials in the vicinity.
