Is it illegal to sell household commercial appliances?

It is illegal to sell commercial appliances alone. Commercial electrical appliances are defined as professional equipment used in commercial places, such as restaurants, offices and medical institutions. These devices have higher power, larger size and more complex functions to meet business needs. However, commercial appliances are not suitable for home use. Household appliances need more consideration in safety and usability to meet the needs of family environment and family members. Commercial appliances lack the necessary characteristics to adapt to the family environment, such as safety measures to prevent children from getting electric shock, size suitable for family size and voltage and current suitable for ordinary household appliances. Therefore, in order to protect the rights and safety of household consumers, many countries have enacted laws and regulations prohibiting the sale of commercial appliances as household appliances, which is illegal.
