Deals with the safety of electrically operated hot cupboards not intended for household use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral, and 480 V for other appliances. Hot cupboards with heated tops, heated display cases, heated crockery dispensers, and heated shelves and tables are also within the scope of this standard. These appliances are used, for example, in restaurants, canteens, hospitals and similar commercial enterprises.
