Which of the following statements correctly describes a luminaire that can be in direct contact with combustible material?

Explanation:
Luminaires that can sit in direct contact with insulation are labeled IC, meaning insulation-contact rated. IC stands for insulation-contact, and these fixtures are designed to operate safely when in direct contact with insulation or other combustibles. That’s why Type IC is the correct description. Non-IC fixtures shouldn’t touch insulation and require clearance or a barrier. An IP rating relates to protection from solids and liquids, not whether the fixture can contact combustibles. So the statement describing a luminaire suitable for direct contact with combustible material is Type IC.
