Why aren't household smart meters equipped with 10A?

The main reasons for not installing 10A on household smart meters are as follows:

1、 The specifications of the electricity meter do not match the household's electricity demand

Household electricity consumption is relatively high: The total power of modern household electrical equipment is generally high, including various household appliances, lighting equipment, etc., and the total power of these devices often exceeds the range that a 10A electricity meter can carry. If a 10A electricity meter is installed, it may not be able to meet the normal electricity needs of the household, resulting in frequent tripping or damage to the meter.

Principles for selecting electricity meter specifications: When choosing an electricity meter, it is necessary to consider the total power of household electrical equipment, simultaneous usage factor, and the possibility of future electricity consumption growth. Usually, there is a certain margin in the specifications of the electricity meter to ensure normal operation during peak electricity consumption periods or future electricity growth. Therefore, a 10A electricity meter is clearly unable to meet this requirement.

2、 Accuracy and safety considerations for electric meters

Meter accuracy: If the household electricity current exceeds the maximum rated current of the meter for a long time, the accuracy of the meter may decrease, resulting in inaccurate measurement. This not only affects the calculation of electricity bills for users, but may also have an impact on the electricity collection of power supply companies.

Electricity safety: A 10A electricity meter may generate heat or even be damaged when subjected to high currents, which not only affects the normal service life of the meter, but also may cause safety hazards such as fires. Therefore, from the perspective of electrical safety, it is not recommended to choose a 10A meter.

3、 Electricity meter upgrade and standardization

Electricity meter upgrade: With the development of technology and the growth of electricity demand, the specifications and performance of electricity meters are constantly being updated and upgraded. At present, the common specifications of electric meters in the market include 5 (20) A, 10 (40) A, 15 (60) A, etc. These specifications of electric meters can better meet the electricity needs of modern households.

Standardization of electricity meters: In order to ensure electricity safety and measurement accuracy, the country has strict standards and regulations for the production and use of electricity meters. Therefore, when choosing an electricity meter, it is necessary to follow relevant national standards and regulations to ensure that the performance and safety of the meter meet the requirements.

In summary, the main reasons why household smart meters do not install 10A are due to the mismatch between meter specifications and household electricity demand, considerations for meter accuracy and safety, as well as considerations for meter updates and standardization. When choosing a home smart meter, it is recommended to choose according to the household's electricity demand and national standards to ensure the safety, accuracy, and reliability of electricity consumption.
