What level does a secondary distribution box in Taiwan refer to
The outgoing line from the low-voltage end of the transformer is 0. 4kV to the distribution cabinet (primary distribution cabinet), then the outgoing line is led to the distribution box (secondary distribution box) in each building, and finally the outgoing line is led to the distribution cabinet. With secondary selective service, each distribution transformer must be able to supply the entire load for maximum reliability benefits. Typically, primary distribution does not directly supply power to devices, secondary distribution.

Principle of DC Distribution Box
A Direct Current Distribution Box also referred to as (DCBD), acts as an interlink between the Solar panels and the inverter. When the Solar panels convert the Solar energy to DC, in such a case, we use the DCDB to control the received DC from it. The output of the DCDB is an input. Solar power generation systems are extremely beneficial in residential, commercial, and industrial sectors, and the trend towards safe, orderly, and reliable DC power management is becoming increasingly important. It protects homes and industries from electrical hazards.

The grounding resistance of the distribution box is too high
After completing the wiring, use a multimeter to measure the resistance from any point on the steel electrical enclosure box to the main grounding electrode. Depending upon the tool cable length and the number of spindles and how they are connected, there are two different alternatives how to meet this requirement. The QST tool cable ground resistance is <3 mOhm/m. Alternative 1: From. Where continuity of service is a high priority, high-resistance grounding can add the safety of a grounded system while minimizing the risk of service interruptions due to grounds. When a ground fault occurs, ground-fault current will flow as in a solidly grounded system. The grounding performance of low-resistivity soils is superior to that of high-resistivity soils, which may necessitate additional steps such as chemical treatment or higher electrode density. These high levels typically require line tripping to remove the fault from the system.
