These requirements cover commercial refrigerators and freezers intended for connection to alternating-current circuits rated not greater than 600 volts. These requirements apply to unitary and remote commercial refrigerators and freezers. For the purposes of this standard, commercial refrigerators and freezers include equipment, such as display cases, reach-in cabinets, meat cases, frozen food and merchandising cabinets, beverage coolers, beverage cooler-dispensers, food service carts, ice cream cabinets, soda fountain units, door panel assemblies and processing water coolers. Self-contained commercial refrigerators and freezers covered by these requirements employ hermetic refrigerant motor-compressors and air- and water-cooled condensers. These requirements do not apply to refrigeration systems such as those used in cold-storage rooms, walk-in coolers, and similar places, that are fabricated in the field. Requirements for the installation of commercial refrigerators and freezers are included in the National Electrical Code, ANSI/NFPA 70, and the Safety Standard for Refrigeration Systems, ASHRAE 15.
