Which is safer, the distribution cabinet or the distribution box?

In terms of safety, the distribution cabinet usually has higher safety performance requirements than the distribution box, but this does not mean that the distribution box is unsafe. The safety differences between the two are mainly reflected in the following aspects:

Use scenarios and voltage levels:
Distribution boxes are mostly used for terminal power distribution in home or small commercial places, such as schools, offices, hospitals and other areas, usually involving low-voltage circuits.
Distribution cabinets are often used in centralized power supply occasions, such as industrial power and building power, and the voltage level involved may be higher, so the requirements for safety performance are also higher.
Structure and function:
The structure of the distribution box is relatively simple, and its main function is power distribution and control. Its internal components and circuit design are relatively basic.
The distribution cabinet has a more complex structure and function. In addition to power distribution, it also has multiple functions such as safety protection, energy metering, easy maintenance, and line arrangement. Its internal components and circuit design are more complex, and usually contain more protection equipment and safety measures.
Operation and maintenance:
The operation and maintenance of the distribution box are relatively simple, usually performed by electricians, and non-professionals can also operate under guidance.
The operation and maintenance of the distribution cabinet usually requires professionals, because its internal structure and functions are relatively complex, and non-professionals may find it difficult to operate and maintain it correctly. This also reflects the higher requirements for the safety of the distribution cabinet to a certain extent.
Safety assessment and testing:
For the distribution cabinet, its safety performance assessment is a comprehensive and meticulous process, including insulation resistance testing, voltage resistance testing, protection level assessment, short-circuit withstand capacity testing and other aspects. These assessments ensure the stability and safety of the distribution cabinet in harsh environments.
Although the distribution box also needs to be evaluated for safety, its evaluation standards and requirements may not be as strict as those of the distribution cabinet.
In summary, the distribution cabinet usually has higher requirements for safety, which is mainly reflected in its usage scenarios, structure and function, operation and maintenance, and safety assessment and testing. However, whether it is a distribution box or a distribution cabinet, as long as it is correctly installed, operated and maintained in accordance with the specifications, it can ensure the safe and stable operation of the power system. Therefore, when choosing which equipment to use, it is necessary to decide according to the specific power demand and occasion, and follow the relevant safety standards and specifications.
