Preventative maintenance is the cheapest insurance a trading shopping centre can buy. At Mount Cotton Central, Commercial Switchboards delivers scheduled preventative maintenance across the centre’s 1600A main switchboard, the local motor control starters and the distribution boards spread throughout the site. This case study covers what that program involves and why a planned approach beats waiting for something to fail.

The scope of the preventative maintenance program
A shopping centre is not one switchboard. Mount Cotton Central runs a 1600A main switchboard, a set of local control starters that drive the centre’s plant such as air conditioning, pumps and mechanical services, and distribution boards spread across the tenancies and common areas. The preventative maintenance program covers all of it as one coordinated scope rather than a series of disconnected callouts.
What a scheduled maintenance visit involves
Each visit follows a set routine. We carry out thermal imaging under load to find hot connections, torque-check terminations, test the protective devices, and inspect every board for signs of heat, wear, moisture and corrosion. Boards are cleaned, labels and schedules are checked, and the whole visit is written up in a dated report that the centre management can hand to an insurer or auditor.
Minor defects found and fixed
The value of a preventative maintenance program is catching the small things early. Across the centre’s boards we have found and rectified minor defects, such as loose terminations and tired components, before any of them developed into a fault or an outage. Fixing a warm connection during a planned visit costs a fraction of what the same connection costs once it has failed on a trading day.
Thermal imaging anchors every visit
The single most useful tool on a preventative maintenance visit is the thermal camera. Run under load, it reveals connections that are heating up long before there is any visible sign, which is exactly how most switchboard failures begin. Pairing the thermal scan with torque checks and protective device testing means each visit catches both the connections that are loosening and the devices that are tiring, and it builds a year-on-year temperature record for every board on the site.
A documented baseline for the centre
Beyond the immediate fixes, a scheduled preventative maintenance program gives Mount Cotton Central a documented baseline for its electrical assets. Every report records the condition of each board, the loads, the temperatures and the actions taken, so centre management always knows the state of the switchboards and can budget for any larger works with evidence rather than guesswork. That record is also exactly what an insurer or an incoming owner wants to see during a due diligence review.
Why preventative maintenance matters for a shopping centre
A trading centre cannot absorb an unplanned switchboard outage. Refrigeration, lighting, security and tenant operations all depend on the boards staying live. Scheduled preventative maintenance keeps those boards reliable, compliant with AS/NZS 61439 and insurable, and it gives centre management a clear record that the electrical infrastructure is being looked after.
Ongoing maintenance with one contractor
Running the main switchboard, the control starters and the distribution boards under one preventative maintenance agreement means a single point of accountability and a consistent record across the whole site. Commercial Switchboards delivers switchboard maintenance and thermal imaging for shopping centres across Brisbane and South-East Queensland.

Switchboard maintenance: frequently asked questions
What does planned switchboard maintenance involve?
Inspection, testing, thermal imaging and checking and tightening connections, all scheduled around trading so the board is never simply switched off.
Why is preventative maintenance worth it?
It catches developing faults before they become the unplanned outages that close shops and cost the most.
How often should a commercial board be maintained?
On a regular planned cycle suited to how hard the board works and how critical the site is.
Do you maintain shopping centre and retail switchboards?
Yes. We run planned maintenance programs for centres and commercial sites with reporting management can rely on.
