See faults before they fail.
Electrical Thermal Imaging Melbourne
Thermal imaging uses infrared technology to detect abnormal heat patterns in electrical systems, identifying faults that are invisible to the naked eye. Loose connections, overloaded circuits, and deteriorating components all generate excess heat before they cause equipment failure, tripped breakers, or fire.
Carlin Co Electrical performs professional electrical thermography across Melbourne using Fluke thermal imaging cameras. Unlike general thermographers, we are licensed electricians (REC 33210) who understand what we are looking at inside a switchboard. When we find a fault, we can diagnose the electrical cause and quote the rectification on the spot.
Our thermal imaging inspections are used by facility managers, strata committees, commercial property owners, and businesses across Melbourne to reduce unplanned downtime, meet insurance requirements, and maintain electrical safety compliance.
What Electrical Thermography Can Identify
Thermal imaging reveals electrical issues long before they become visible or cause failure. Here are the most common faults our Fluke cameras detect in Melbourne switchboards and electrical installations.
Loose Connections
Loose terminations on circuit breakers, busbars, and cable lugs create high-resistance joints that generate excess heat under load. Left undetected, these connections deteriorate over time and can cause arcing, equipment damage, or fire. Thermal imaging pinpoints the exact connection so it can be re-torqued or replaced.
Circuit Overloading
Circuits carrying more current than their rated capacity show elevated temperatures across the entire conductor and protective device. Thermal imaging identifies overloaded circuits before the wiring insulation degrades, allowing load redistribution or additional circuit installation before a failure occurs.
Phase Imbalance
In three-phase installations, uneven load distribution across phases causes certain conductors and devices to run hotter than others. Thermal imaging quantifies the temperature differential, making it straightforward to rebalance loads and reduce stress on individual phases and the neutral conductor.
Switchgear and Component Heating
Circuit breakers, contactors, isolators, and other switchgear components degrade over time. Internal contact wear, spring fatigue, and corrosion increase resistance within the device. Thermal imaging identifies components that are running abnormally hot compared to identical devices under similar load, flagging them for replacement before they fail.
Busbar Hotspots
Busbars distribute power within switchboards and distribution boards. Corrosion, poor plating, or insufficient torque on busbar joints creates localised hotspots that can escalate to catastrophic failure. Thermal imaging detects these hotspots under normal operating conditions without the need to de-energise the board.
Developing Faults
Many electrical faults develop gradually. A connection that is slightly warm today may be critically hot in six months. Regular thermal imaging inspections establish a baseline for each installation, allowing trending analysis that catches deteriorating conditions well before they reach a dangerous level.
Real Thermal Scan Results From Our Fluke Camera
These are actual thermal images captured during our inspections across Melbourne. Each image shows temperature data overlaid directly on the electrical components, making it possible to identify exactly where heat is building and how severe the issue is.

Reading a Thermal Image
In thermal imaging, colour represents temperature. Warmer areas appear as lighter or brighter colours on the spectrum, while cooler areas appear darker. The temperature scale on the right of each image shows the range being measured. What matters most is not the absolute temperature, but the temperature difference between identical components under similar load. A connection running significantly hotter than its neighbours is the primary indicator of a developing fault.
Need a Thermal Imaging Inspection?
We provide thermal imaging inspections for commercial switchboards, distribution boards, and electrical installations across Melbourne. Call us on 0432 632 346 or book an inspection online.
Commercial Electrical Thermal Imaging
Commercial and industrial electrical systems operate under higher loads and tighter uptime requirements than residential installations. An unexpected switchboard failure in a warehouse, office building, retail centre, or manufacturing facility can mean lost revenue, spoiled stock, safety risks, and expensive emergency repairs.
Thermal imaging is a non-invasive, non-contact inspection method that can be performed while equipment remains energised and operational. There is no need to shut down production or disrupt building operations during the inspection. Our thermographer scans all accessible switchboards, distribution boards, motor control centres, and electrical connections under normal load conditions.
Many insurers and facility management contracts now require regular thermal imaging inspections as part of their risk management framework. Our detailed reports meet these requirements and provide documented evidence of your electrical maintenance program.
Common commercial applications include office buildings, retail premises, warehouses, factories, data centres, aged care facilities, schools, strata properties, and any facility with critical electrical infrastructure.
Switchboard Thermal Imaging Melbourne
Switchboards are the most common focus of electrical thermal imaging inspections. Every connection point in a switchboard is a potential source of heat buildup, and the enclosed environment means that heat from one fault can accelerate deterioration of adjacent components.

During a switchboard thermal scan, we image every circuit breaker, RCD, contactor, busbar connection, cable termination, and neutral bar. We compare component temperatures against each other and against the ambient environment to identify any abnormal heat signatures.
Because we are licensed electricians, not just thermographers, we understand the electrical significance of what the camera reveals. A 15-degree rise on a busbar joint tells us something different than a 15-degree rise on a circuit breaker body, and the rectification approach is different for each. This electrical expertise is what separates our service from general thermal imaging providers.
If your switchboard was installed more than ten years ago, or if you have experienced unexplained tripping, a thermal scan is one of the most cost-effective ways to assess its condition. We frequently pair thermal imaging with switchboard upgrades when the scan reveals that the board has reached the end of its serviceable life.

The Carlin Co Thermal Imaging Report
Every inspection includes a comprehensive report that documents our findings with thermal and visual images, temperature data, and clear recommendations. Our reports are designed for facility managers, building owners, and insurers.
Thermal Images
High-resolution thermal images of every inspected component, clearly labelled with location references and temperature readings. Each thermal image is paired with a standard visual photograph for easy identification.
Severity Ratings
Each identified fault is classified by severity using industry-standard criteria based on temperature rise above ambient and comparison to similar components. This prioritisation helps you address the most critical issues first.
Rectification Advice
Because we are licensed electricians, our reports include specific electrical rectification recommendations for each fault. We explain what is causing the issue and what needs to be done to fix it, not just that a hotspot exists.
Example thermal capture showing hotspot identification at 21.8 degrees C in a distribution panel. Images like this form the basis of every Carlin Co thermal imaging report.
Reports are delivered digitally within five business days of the inspection. They can be shared directly with your insurer, facilities team, or compliance records. If urgent faults are identified during the inspection, we will advise you immediately on site.
Our Thermal Imaging Inspection Process
Our process is designed to deliver accurate results with minimal disruption to your operations. Here is what to expect.
Step 1: Pre-Inspection Planning
We discuss your site, the number and location of switchboards, access requirements, and any specific concerns. For accurate results, we schedule the inspection during normal operating hours when electrical equipment is under typical load.
Step 2: On-Site Thermal Scan
Our electrician opens each switchboard and scans all connections, protective devices, busbars, and cable terminations with our Fluke thermal camera. Visual photographs are taken alongside thermal images for reference. The equipment remains energised throughout, so there is no interruption to your power supply.
Step 3: Analysis and Reporting
Back in the office, we analyse every thermal image, classify faults by severity, and compile our findings into a detailed report with images, temperature data, and rectification recommendations. Reports are delivered within five business days.
Step 4: Rectification (If Required)
If faults are found, we can quote and carry out the electrical rectification work. Because we identified the issue, we know exactly what needs to be fixed. This eliminates the back-and-forth between a thermography company and a separate electrician, saving you time and cost.

Understanding Temperature Severity Classifications
Not every warm connection is an emergency. The electrical industry uses a standardised classification system to assess the severity of thermal anomalies based on temperature rise above ambient and comparison with similar components.
Priority 4
1-10 degrees C above ambient
Monitor. Possible developing condition. Recheck at next scheduled inspection.
Priority 3
11-20 degrees C above ambient
Investigate. Schedule repair within the next maintenance window.
Priority 2
21-40 degrees C above ambient
Serious. Repair as soon as practical. Monitor closely until rectified.
Priority 1
40+ degrees C above ambient
Critical. Immediate attention required. Risk of failure or fire.
Our reports use this classification system so you can prioritise rectification work based on risk. Priority 1 and 2 faults are flagged immediately on site during the inspection so that urgent action can be taken without waiting for the formal report.
Thermal Imaging as Preventative Maintenance
Reactive electrical maintenance costs more than preventative maintenance in almost every scenario. An emergency callout to diagnose and repair a failed switchboard costs significantly more than a scheduled thermal scan that identifies the developing fault weeks or months earlier.
Thermal imaging fits naturally into a preventative maintenance program because it is non-invasive, fast, and requires no shutdowns. A typical commercial switchboard scan takes 30 to 60 minutes depending on the number of boards, and the equipment stays energised throughout. This makes it practical to schedule inspections during business hours without disrupting operations.
Regular thermal scans also build a historical record of your electrical system’s condition. Comparing images from consecutive inspections reveals trends that would be invisible from a single snapshot, helping you plan maintenance and capital expenditure more effectively.
For facilities subject to Essential Safety Measures (ESM) requirements or insurance compliance audits, thermal imaging reports serve as documented evidence of proactive electrical maintenance.
Scheduled Thermal Imaging Programs
For businesses and property managers who want ongoing protection, we offer scheduled thermal imaging programs. We set up a regular inspection cycle, typically annually or bi-annually, and manage the scheduling, inspection, reporting, and any follow-up rectification work.
Scheduled programs are popular with strata managers overseeing multiple properties, facility managers responsible for commercial or industrial buildings, and businesses with insurance or compliance requirements that mandate regular electrical inspections.
Each inspection builds on the last. We retain your historical thermal data so that trending analysis is available across inspection cycles, giving you a clear picture of how your electrical infrastructure is ageing and where future investment is needed.

Thermal Imaging FAQs
How much does electrical thermal imaging cost?
The cost depends on the number of switchboards and the size of the installation. A single commercial switchboard scan with a detailed report typically starts from a few hundred dollars. Larger sites with multiple boards are quoted based on the scope of work. Contact us for a quote specific to your property.
Does my power need to be turned off during the inspection?
No. Thermal imaging is performed while your electrical system is energised and operating under normal load. This is one of the key advantages of the technology. Your business operations continue uninterrupted during the inspection.
How often should thermal imaging be done?
For most commercial properties, an annual thermal scan is recommended. High-demand or critical facilities may benefit from inspections every six months. Your insurer or facility management contract may specify a required frequency. We can advise on the right interval for your situation.
What equipment do you use?
We use Fluke thermal imaging cameras, which are the industry standard for electrical thermography. Fluke cameras provide high thermal sensitivity and resolution, ensuring accurate temperature measurement and reliable detection of developing faults.
Can you fix the faults you find?
Yes. Unlike standalone thermography companies, Carlin Co Electrical holds REC licence 33210 and can carry out all electrical rectification work ourselves. When we identify a fault, we can quote the repair and schedule the work without you needing to engage a separate electrician.
Is thermal imaging required by insurance?
Some commercial insurance policies and facility management contracts require or recommend regular thermal imaging as part of their risk management framework. Even where it is not mandatory, a thermal imaging report demonstrates proactive maintenance and can support your position in the event of a claim. Check with your insurer or broker for your specific requirements.
Do you service residential properties?
While thermal imaging is most commonly used in commercial and industrial settings, we also provide the service for residential properties where there is a specific concern.
