1. Power outlets must be products that have passed inspections by relevant national product quality supervision authorities.
2. Power outlets within residential dwellings should be of the safety-type design; in damp locations such as bathrooms, splash-proof outlets must be used.
3. The rated current of a power outlet must be at least 1.25 times the rated current of the equipment intended for use with it. Generally, standard single-phase power outlets have a rated current of 10A, while dedicated outlets for specific appliances are rated at 16A; for special high-power household appliances, the corresponding distribution circuit and power connection method should be selected based on the actual power capacity.
4. For the sake of convenient access, a combined outlet unit should ideally consist of two sockets, and in no case should the total number of components (including switches) exceed three.
5. For household appliances where connecting to the power supply poses a risk of electric shock, outlets equipped with an integral switch for disconnecting the power supply should be utilized.
6. In relatively damp environments, the installation of power outlets must be accompanied by the simultaneous installation of a waterproof enclosure.
