NRG were engaged to carry out a statutory compliance inspection audit on all site switchboards including MCC’s and sub-inspections. All switchboards were checked for degradation, design failings, documentation availability, faulty components and compliance with Australian standards and mining regulations and conformance to current site safety standards. The nature of defects and deficiencies were prioritised to identify which switchboards required immediate attention.

Priority 1 rectification and upgrades to switchboards followed to bring all components up to site and Australian Standards. Rectification works varied in scale depending on switchboard condition and covered completion of RCD statutory testing, generation and installation of legends and single line diagrams, upgrade of switchboard earthing, and 18 switchboards were replaced with new switchboards, most of custom sheet metal manufacture.

As a result of the project, all re-commissioned switchboards were installed and the client was given useful statutory compliance data to ensure continued compliance and ongoing maintenance. Priority 1 works are now completed, with NRG also retained to undertake rectifications to priority 2 defects.
