What type of protection is required for recessed incandescent fixtures?

Recessed incandescent fixtures require thermal protection due to the heat generated by the incandescent bulbs. These fixtures are often installed in ceilings or walls, and the insulation surrounding them can become a significant fire hazard if the heat is not properly managed.

Thermal protection typically comes in the form of insulation contact (IC) rated fixtures or the use of thermal insulation barriers that ensure that the heat produced by the fixture does not come into direct contact with any combustible materials, including insulation. This is crucial to prevent overheating, which could lead to electrical fires or damage to the fixture and surrounding materials.

Understanding this requirement emphasizes the importance of safety in electrical installations, especially in areas where insulation is present. Therefore, thermal protection is essential for recessed incandescent fixtures to minimize risks associated with excessive heat.
