In 2014, Seven Hills High School had decided to go for an electrical upgrade to reduce electricity demand component cost of an aging system. Southern Cross Switchboards role was to manufacture a new Main Switchboard (Rated at 400A, 30kA for 1 sec), and 2 new switchboards that were to replace the existing switchboards.

The custom built Main Switchboard was located outdoor and rated IP56 with a custom made sloping rain hood. The other 2 switchboards were bit of a design challenge for Southern Cross Switchboards due the unique positioning required within the board for the equipment. The cabling from the disconnected old switchboard into the new boards was a challenge within itself. This was made a lot easier over all with the modification of the switchboard and hence eliminated the connection issues.
