The frequent opening and closing of the electric meter box has a relatively small impact on the electricity consumption of household appliances, because the main function of the electric meter box is to measure and record electricity consumption, without involving direct control and regulation of current. However, frequent opening and closing of the meter box may have certain impacts on the meter itself, mainly reflected in the following aspects:

Meter lifespan: Frequent opening and closing of the meter box may accelerate the wear and tear of internal mechanical components, thereby affecting the service life of the meter. Although the design of modern electricity meters has taken durability into consideration, long-term frequent switching operations may still cause unnecessary losses.

Safety hazards: If there is improper operation or poor maintenance of the electric meter box during the switching process, it may cause safety hazards such as poor contact, short circuit, etc., which will affect the safety of household electricity use.

Electricity usage habits: From the perspective of electricity usage habits, frequent opening and closing of the meter box may not be necessary. Unless it is necessary to cut off the power supply for maintenance or protection of electrical equipment in specific circumstances, frequent operation of the meter box is generally not necessary.

Therefore, in order to reduce unnecessary losses and safety hazards, it is recommended to minimize the number of times the meter box is opened and closed, and regularly inspect and maintain the meter box to ensure that it is in good working condition. At the same time, attention should be paid to safe use of electricity during the process, avoiding excessive load and improper operation.
