  • SCOPE

    1 Scope

    1.1 These requirements cover commercial motor-operated food-preparing machines intended for use in accordance with the National Electrical Code.

    1.2 These requirements do not cover machines rated more than 600 V; nor do they cover machines involving universal motors rated more than 250 V.

    1.3 These requirements cover coffee grinders, vegetable cutters, food mixers, nonrefrigerated ice cube dispensers, and other motor-operated machines usually found in commercial kitchens, restaurants, food processing establishments, bakeries, or other business establishments where food is prepared or processed.

    1.4 A machine that utilizes some other source of energy, such as gas or steam, in addition to electric energy will be investigated under these requirements and under such additional requirements as are applicable to the machine under consideration.

    1.5 These requirements also cover portable rechargeable battery-powered appliances for indoor or outdoor use with rechargeable non-user and user-replaceable batteries; see Appendix b.
