Yes, you calculate the size of cable (wire) according to current of the connected load.

how can i calculate copper cable to bus bar size e.g: 300mm2 cu/pvc/pvc cable, change in to bus bar size

To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.

There is actually no specific formula used to work out cable size. In order to determine the type of cable you need and the size you need, you need to know the source of the supply, the voltage of the system, the ambient temperature, and the method you plan on laying out the cable.
