Thermal insulation must not be installed above a recessed luminaire or within how many inches of its enclosure?

The correct answer is three inches because there are specific safety standards and guidelines established for the installation of thermal insulation around recessed luminaires. These regulations are in place to prevent overheating, which can occur if insulation is placed too close to the light fixture.

When a recessed luminaire operates, it generates heat, and if insulation is allowed to come into direct contact with it or be positioned too closely, it can create a fire hazard. By maintaining a distance of three inches from the enclosure of the recessed light, you help ensure proper airflow and heat dissipation, minimizing the risk of any potential fire hazards.

It’s important to adhere to these standards to not only safeguard residential and commercial spaces but also to comply with building codes that govern electrical installations.
