Cable Current Carrying Capacity and Derating

When it comes to selecting the right cable for a DC or AC application on your next commercial solar project the standard approach is to calculate what current will be carried through the cable, work out the cable run distances, then the volt drop DC and volt rise AC particulars.

For example, in AS4777 the example references Table 7, column 24 in regards to current carry capacity and then another table for the mv/A.m factor used to determine the voltage rise on the AC side. This example isn’t the worst case scenario but is close.

In this presentation, we go through the cable selected for a 300 kW commercial solar system looking at CCC, location and method of installation.

Enjoy.
