Do you understand the national standard for installing electric meter boxes

1, National standard for installation of electric meter boxes
1. Installation location: The meter box should be installed at the electrical terminal equipment, with good electrical isolation, ventilation, fire prevention and other safety conditions.
2. Installation height: The bottom of the meter box should be at least 1.5 meters above the ground for easy maintenance and repair.
3. Installation bracket: The meter box should be fixed to the wall with a dedicated steel plate bracket or embedded angle steel to ensure safety and reliability.
4. Connection line: The cables between the meter box, transformer, and distribution box should comply with the power system standards, and the connection terminals must be tightened. The contact voltage drop should be less than 5%.
5. Grounding protection: The metal casing and grounding system of the meter box should comply with the requirements of the national power equipment safety regulations, and be safe and reliable.
6. Electricity metering: The meter box should comply with the requirements of the national electricity metering standards to ensure accurate energy metering.
2, Precautions before installation
Before installation, a comprehensive inspection of the meter box should be conducted to confirm that its various parameters meet the requirements of the power system.
2. Before installation, check whether the selected steel plate bracket or angle steel meets national standards to avoid safety hazards caused by quality issues.
3. Before installation, the grounding circuit should be checked to confirm that the grounding system and casing are fully connected and comply with safety regulations.
Before installation, cables that meet the standards of the power system should be selected to ensure that the connection and contact voltage drop meet the requirements.
The above are the national standards for installing electric meter boxes and the precautions to be taken before installation. When installing electric meter boxes, it is necessary to carefully follow the national standards to ensure the safe and stable operation of the power system.
