Which type of cooking hood allows the installation of luminaires if identified for use?

The correct response is commercial cooking hood. Commercial cooking hoods are designed for use in professional kitchens and are typically larger and more robust than residential units. When these hoods are identified for the installation of luminaires, they can accommodate lighting fixtures that enhance visibility and safety for kitchen staff.

This provision allows for the integration of lighting directly into the cooking environment without compromising safety or functionality. The NEC recognizes that specific commercial cooking hoods can safely include lighting when designed or classified for such use, ensuring they meet necessary safety standards during operation.

In contrast, residential cooking hoods are generally not designed to accommodate luminaires within the unit itself, and portable cooking hoods are usually temporary and may not support additional fixtures. Industrial cooking hoods may also differ in design and application requirements, often focusing on heavy-duty use rather than integrating lighting solutions. Therefore, the commercial cooking hood is uniquely equipped to allow luminaires when appropriately identified for that purpose.
