After 25 years of operation, the Sydney Convention and Exhibition Centre Darling harbour closed in January 2014 to make way for the development of the new $1 billion event and exhibition facilities, due for completion in 2016.

A Stowe/Fredon join venture were awarded the $80 million project to undertake the electrical services installation. This included the design, supply, delivery and installation as part of the redevelopment of the site.

In June 2014 Southern Cross Switchboards were awarded the project of supplying and rework of two 1600A Main Switchboards with a quick turnaround of 12 days.

The project consisted of removing the existing MSB’s and have them shipped to our workshop in Silverwater. Once the boards were in the work shop we stripped the boards of all existing switchgear and components. We then re-designed the switchboard whilst maintaining the existing frame. Both boards required a 1600A Service Protection Device along with Supply Authority Current Transformers. The existing MSB2 was too small so we had to manufacture and join a new tier to allow for the supply authority section, which then fed a number of breakers ranging from 800A to 100A MCCBS. There were outdated chassis on the board that we had to source breakers to suit. Both Boards were roughly 3m long and stood 2.3m tall. We managed to utilise some of the existing busbar. However in some sections we had to completely re design the arrangement.

Once the boards were complete we then carried out our Inspection and Test Plan (ITP). We the transported the switchboards to Darling Harbour to Fredon/Stowe. Total duration of this project was 12 days ” Phew “.
