Switchboard Thermal Imaging
Electrical & Switchboard Thermography
Electrical faults do not always provide an obvious warning before failure.
Loose connections, overloaded circuits, deteriorating components and high-resistance joints can generate abnormal heat long before there is a visible problem.
We provide professional electrical thermography and switchboard thermal imaging inspections for commercial, industrial, rural and other electrical installations.
As qualified electricians and a Level 2 Certified Thermographer, we can not only identify abnormal thermal patterns but also understand the electrical system, investigate the likely cause and provide practical recommendations where further action is required.
Electrical Thermal Imaging Inspections
Thermal imaging allows electrical equipment to be inspected while operating, helping identify abnormal temperature differences that may indicate developing faults.
We can carry out thermographic inspections on equipment including:
- Main switchboards
- Distribution boards
- Motor control centres
- Pump control panels
- Circuit breakers
- Contactors
- Motor starters
- Busbars
- Cable terminations
- Electrical connections
- Isolators
- Variable-speed drives
- Soft starters
- Control equipment
- High-load electrical circuits
Thermography can be used as part of a preventative maintenance program or to investigate equipment where overheating or an electrical fault is suspected.
Why Electrical Thermography?
Many electrical failures develop gradually.
A loose or deteriorating electrical connection may continue operating while producing increasing heat, sometimes without causing a circuit breaker or other protective device to operate.
Thermal imaging may help identify problems such as:
- Loose electrical connections
- High-resistance joints
- Uneven phase loading
- Overheating terminals
- Overloaded circuits
- Deteriorating electrical components
- Faulty breakers or contactors
- Abnormal heating within motor control equipment
- Poor cable connections
Identifying these issues early can allow repairs to be planned before they develop into more serious failures.
Switchboard Thermal Inspections
Switchboards contain numerous electrical connections and components that can be affected by heat, loading, vibration and ageing.
A thermal inspection can identify areas operating at abnormal temperatures and help highlight components requiring further investigation.
Our switchboard inspections can include:
- Main incoming connections
- Circuit breakers
- Busbars
- Neutral connections
- Cable terminations
- Contactors
- Motor protection
- Control equipment
- Sub-main connections
- High-current circuits
Where abnormal heating is identified, we can assess the thermal pattern together with the electrical installation and determine what further testing or corrective work may be required.

Why Choose Us for Electrical Thermography?
Thermal imaging is more than simply pointing a camera at a switchboard.
Correct interpretation requires an understanding of electrical systems, equipment loading, thermal patterns and the operating conditions present at the time of the inspection.
Level 2 Certified Thermographer
Our Level 2 thermography certification provides advanced training in thermal inspection techniques, analysis and interpretation.
This allows us to assess thermal patterns in greater detail and consider factors that can affect the accuracy of an inspection.
Qualified Electricians
We are also qualified electricians, giving us an important advantage when carrying out electrical thermography.
We understand the equipment being inspected and can relate thermal findings to:
- Electrical loading
- Circuit design
- Connection condition
- Motor operation
- Protection equipment
- Switchboard components
- Electrical faults
This means our inspections are backed by practical electrical knowledge rather than thermal imaging alone.
Inspection, Diagnosis & Repair
Where an issue is identified, we can also assist with further electrical testing and repairs.
This provides a more complete service from the initial thermal inspection through to investigation and rectification where required.
Preventative Electrical Maintenance
Thermography is particularly valuable as part of a scheduled preventative maintenance program.
Regular inspections can help businesses monitor critical electrical equipment and identify changes before they result in an unexpected breakdown.
Thermal inspections may be particularly useful for:
- Manufacturing facilities
- Workshops
- Commercial buildings
- Pumping stations
- Wastewater treatment plants
- Irrigation systems
- Industrial sites
- Agricultural facilities
- Motor control centres
- Critical electrical switchboards
For sites where electrical failures could cause significant downtime, periodic thermal inspections can provide valuable information about the condition of the electrical installation.
Thermography for Pumps & Motor Control Systems
Our extensive experience with pumps, motors and control systems also allows us to provide thermal inspections of electrical equipment associated with pumping installations.
This may include:
- Pump control panels
- Motor starters
- Contactors
- Overloads
- Variable-speed drives
- Soft starters
- Motor circuits
- Pump station switchboards
- Wastewater treatment plant controls
- Irrigation pump systems
Thermal imaging can help identify abnormal heating before a failure affects critical pumping equipment.
Thermal Inspection Reports
Following an inspection, we can provide a clear report documenting significant thermal findings.
Depending on the scope of the inspection, reports may include:
- Thermal images
- Corresponding visual images
- Equipment identification
- Observed temperature differences
- Description of abnormal findings
- Assessment of the issue
- Recommended further investigation or corrective action
Reports can be used for maintenance planning, internal records and ongoing condition monitoring.
Where previous inspection data is available, future inspections can also help identify whether thermal conditions are changing over time.
When Should You Consider a Thermal Inspection?
An electrical thermal inspection may be worthwhile if:
- Your switchboards have not been inspected recently
- Equipment operates under high electrical load
- You have experienced unexplained electrical failures
- Circuit breakers or components are overheating
- Electrical equipment is critical to business operations
- You are developing a preventative maintenance program
- Your site contains ageing switchboards or control equipment
- You want to identify potential faults before planned shutdown work
- You operate critical pumps, motors or automated equipment
Thermal imaging can often be completed while equipment is operating, allowing the electrical system to be assessed under normal load conditions.
Electrical Fault Finding Following a Thermal Inspection
A thermal image can identify that something is operating abnormally, but further testing may be required to determine why.
Because we are qualified electricians, we can carry out additional fault finding where required.
This may include:
- Electrical current measurements
- Phase comparison
- Connection inspections
- Circuit testing
- Component testing
- Motor testing
- Load assessment
- Checking contactors and protection equipment
This allows thermal findings to be investigated properly rather than simply recording a hot spot without determining the cause.
Need an Electrical Thermal Inspection?
Whether you require a one-off switchboard inspection or want to introduce thermal imaging into your preventative maintenance program, we can provide professional electrical thermography backed by practical electrical experience.
With the combination of Level 2 thermography certification and qualified electrical experience, we can identify abnormal thermal conditions, understand the equipment being inspected and provide clear recommendations on what should happen next.
