USE

This category covers complete luminaires intended for general and special-purpose illumination, and component fittings and retrofits intended for field assembly to or into complete units.

SPECIAL-USE LUMINAIRES

Cooking Hood Luminaires — Luminaires intended for use in nonresidential occupancies in exhaust ducts or hoods above cooking equipment are marked "SUITABLE FOR USE WITHIN COMMERCIAL COOKING HOODS" and "MOUNT A MINIMUM OF 1.2 M (4 FT) ABOVE COOKING SURFACE." Such luminaires are for installation in accordance with ANSI/NFPA 96, "Ventilation Control and Fire Protection of Commercial Cooking Operations," and Section 410.10(C) of ANSI/NFPA 70, "National Electrical Code" (NEC).

Recessed cooking hood luminaires are additionally marked with a minimum spacing marking: "INSTALL WITH MINIMUM SPACINGS BETWEEN A) CENTER-TO-CENTER OF ADJACENT LUMINAIRES: ___INCHES; B) TOP OF LUMINAIRE AND AN OVERHEAD BUILDING MEMBER: ___INCHES; AND C) LUMINAIRE CENTER TO SIDE BUILDING MEMBER:___INCHES." The recessed cooking hood is intended to be installed in a hood that maintains these minimum spacings.

Air-handling Luminaires — Luminaires suitable for air handling use are marked "SUITABLE FOR AIR HANDLING USE." For information on the use of air-handling luminaires in fire-rated ceiling constructions, reference should be made to the design information section under Fire Resistance Ratings (BXUV). For applicable requirements covering air-handling installations, reference should be made to ANSI/NFPA 90A, "Installation of Air-Conditioning and Ventilating Systems."

Some recessed air-handling luminaires are restricted to certain applications because of certain features and are marked as follows: "VENTILATING OR COOLING AIR ONLY,""ONLY FOR USE IN CEILING PLENUM OF NONCOMBUSTIBLE CONSTRUCTION OR WITH AIR HANDLING PARTS THAT COVER VENT OPENINGS" or "INSTALL ONLY IN ENVIRONMENTAL AIR HANDLING SPACES WHERE A COMPLETE METAL ENCLOSED WIRING SYSTEM IS PROVIDED."

LUMINAIRE INSTALLATION MARKINGS

Unless otherwise indicated under the category for a specific type of luminaire, all luminaires are marked indicating the location where they can be used:

Luminaires marked "DRY LOCATIONS ONLY" are intended to be installed in indoor dry locations.
Luminaires marked "SUITABLE FOR DAMP LOCATIONS" are intended to be installed in damp or dry locations.
Luminaires marked "SUITABLE FOR WET LOCATIONS" are intended to be installed in wet, damp or dry locations.

The locations are defined in Electrical Equipment for Use in Ordinary Locations (AALZ) and the NEC.

In addition to the dry-, damp- or wet-location markings, a luminaire may be optionally investigated and marked for ingress protection in accordance with IEC 60529, "Degrees of Protection Provided by Enclosures (IP Code)." IP code markings are supplemental and not intended to replace dry-, damp- or wet-location markings.

Luminaires investigated for or restricted to a particular mounting location for suitability to wet locations are additionally marked "SUITABLE FOR MOUNTING WITHIN 1.2 M (4 FT) OF THE GROUND,""SUITABLE FOR GROUND-MOUNTED RECESSED,""LIMIT RANGE OF ADJUSTMENT TO (instruction)" or "COVERED CEILING MOUNT ONLY."

Luminaires investigated for or restricted to a particular mounting location are marked "WALL MOUNT ONLY,""FOR CEILING MOUNTING ONLY" or "MOUNTING ORIENTATION" (such as "This End Up").

Luminaires are marked with a supply wire temperature rating "MIN __C SUPPLY CONDUCTORS," if intended for greater than 60°C supply wiring. Luminaires rated for over 90°C supply wiring are additionally marked "NOT FOR USE IN DWELLING."

Luminaires that include an integral raceway intended to comply with Section 410.64(A) of the NEC are marked "SUITABLE FOR USE AS RACEWAY," and are additionally marked to include the maximum number, size and type of conductors they are intended to accommodate. See Surface Metal Raceways (RJBT) for raceways that can be assembled and installed as lighting units.

Some luminaires are only suitable for use with specific lamp types and are so marked. However, luminaires are not investigated or intended for use with sun lamps.

Luminaires containing components that require the luminaire to be connected only to an alternating-current circuit are marked "60 Hz" or "AC ONLY."

Luminaires designed for connection to a proprietary wiring system will specify the name and part number of the proprietary system and all cautionary or other markings required for the system. These systems are covered under Manufactured Wiring Systems (QQVX).

Luminaires designed for connection to other than nominal 120 V supply and/or a 2-wire branch circuit are marked to identify the voltage supply or type of branch circuit or both.
