What is the thickness of the sheet metal for the electrical distribution box cabinet?
The thickness of the sheet metal
for the electrical distribution box cabinet usually has the following regulations:
- **Switch box**: The thickness of the steel plate of the box body shall not be less than 1.2mm.
- **Electrical distribution box**: The thickness of the steel plate of the box body shall not be less than 1.5mm.
- **Power distribution cabinet**: The thickness of the steel plate of the cabinet body shall not be less than 2.0mm.

In addition, there are some more specific requirements:
- The floor-standing cabinet should be made of 2.0mm thick cold-rolled steel plate.
- For lighting electrical distribution boxes and control boxes with a size greater than or equal to 600mm, 2.0mm thick
cold-rolled steel plates should be used, and for those less than 600mm, 1.5mm thick cold-rolled steel plates should
be used.
- When the width of the electrical distribution box is greater than 500mm and less than 800mm, the thickness of the steel
plate should not be lower than 1.2mm; when the width is greater than or equal to 800mm, the thickness of the steel
plate should not be lower than 1.5mm.
- When the semi-perimeter of the household box body is ≥ 900MM, the thickness of the steel plate should not be less
than 1.5mm, and when the semi-perimeter is < 900MM, the thickness of the steel plate should not be less than 1.2mm.
- When the semi-perimeter of the meter box and non-standard box body is ≥ 1100MM, the thickness of the steel plate
should not be less than 2.0mm, and when the semi-perimeter is < 1100MM, the thickness of the steel plate should not
be less than 1.5mm.
In practical applications, it is also necessary to comprehensively consider factors such as the usage environment, installation
method, and protection level of the electrical distribution box to select an appropriate sheet metal thickness to ensure the
safety, reliability, and durability of the electrical distribution box.
