Standards
The DIN standards DIN 43670 and DIN 43671 outline the ampacity for conductors made of aluminum and copper under various conditions in tabular form. Correction factors take account of deviating conditions. These factors are listed for:
– Conductivity-dependent load changes
– Different temperatures
– Different bar orientation and routing
– Geometry-based change for AC applications
– Height changes
DIN 43670 lists the values for aluminum busbars, and Part 2 of this standard specifies the continuous ampacity values for copper- clad busbars made of aluminum. DIN 43671 lists the corresponding values for copper busbars.
