The bus duct current-carrying capacity query and differential
The first step

Manufacturer to provide CCC Type test report,And checked with the original(Not missing page)。

The second step

Provide the current(A single value,Such as800A,Non1000A-630A)Temperature rise test report,The report should contain a photo、The conductor specifications、Through the current and the testing point temperature to rise。

The third step

The goods to the scene,Check the goods and products structure in a report、Conductor specification are consistent。

Step 4

The conductor loop resistance tester testing resistivity,Should comply with GB/T 5585.1-2005,The resistivity ρ ≤ 0.01777 Ohm·Square millimeter/M。
