According to the national electric power standard, the electrical equipment of 10 dry tile belongs to large electrical equipment, which is mainly suitable for commercial use. The power of general commercial wok is between 2kW and 5kW, so the commercial electric wok with 10 dry tile can meet the needs of commercial cooking, which is enough. However, in actual use, if other electrical equipment is operated at the same time, it is necessary to scientifically evaluate the safety of the equipment in combination with power load, power grid capacity and other related factors to avoid potential safety hazards such as power overload. At the same time, we should also pay attention to the cost and efficiency of electricity consumption in order to achieve the purpose of energy saving and emission reduction.
