MSB main switchboard schematics — Brisbane data centre.
Case study: complete schematics, single-line diagrams and panel-builder shop drawings for 2 × 2500 A main switchboards in a Brisbane Tier III data centre — to AS/NZS 3000, AS 61439 and the data-centre owner’s standards.
Project overview
ASTCAD produced the complete electrical documentation for 2 × 2500 A main switchboards installed in a new Brisbane Tier III data centre. Documentation covered single-line diagrams, schematics, panel-builder shop drawings, cable schedules and as-built drawings.
The challenge
The data centre required A/B redundant feeds with automatic transfer switching and full SCADA integration. The owner had strict labelling and segregation standards beyond AS 61439, and the switchboards had to undergo type-test verification before site delivery.
Our approach
- Single-line diagrams for A and B feed architecture
- Detailed schematics for ATS, sub-circuits and SCADA tie-points
- Panel-builder shop drawings with internal layouts and busbar runs
- Cable schedules and termination diagrams
- Type-test compliance verification package
Deliverables
- 182 electrical drawings (SLDs, schematics, shop)
- Cable schedule (2,140 cables)
- Type-test compliance package
- Commissioning test sheets
- As-built documentation set
Outcome
The switchboards were built and commissioned within the data centre’s tight programme. SCADA integration testing passed first time. The owner has commissioned a further 6 MSB packages of similar specification under the same documentation standard.
