Top 5 Electrical Faults Found During Thermal Imaging Inspections

Common Electrical Issues Detected with Thermal Imaging

Thermal imaging is one of the most effective ways to detect hidden electrical faults inside switchboards before they lead to serious failures.

At Atomic Electrical Group, we carry out electrical thermal imaging inspections across commercial, industrial and strata properties, consistently identifying the same high-risk issues.

Here are the most common faults found during thermal inspections.

🔶 1. Loose Electrical Connections

Loose connections are one of the most common and dangerous faults found during inspections.

They create electrical resistance, which leads to heat buildup over time.

If left untreated, this can result in:

• Burnt terminals
• Equipment failure
• Electrical fires

🔶 2. Overloaded Circuits

Overloaded circuits occur when electrical demand exceeds the circuit’s capacity.

Thermal imaging allows these faults to be identified through excessive heat in cables and circuit breakers.

Common causes include:

• Additional equipment added over time
• Poor load distribution
• Undersized circuits

🔶 3. Failing Circuit Breakers

Circuit breakers can deteriorate over time and may not operate correctly under load.

Thermal inspections detect abnormal heat patterns that indicate internal failure.

Signs include:

• Hot breakers compared to others
• Uneven temperature distribution
• Repeated tripping

🔶 4. Cable Overheating

Overheating cables are often caused by:

• Poor terminations
• Excessive electrical load
• Damaged or degraded insulation

Using switchboard thermal imaging, these issues can be identified early before insulation failure or short circuits occur.

🔶 5. Unbalanced Electrical Loads

In three-phase systems, unbalanced loads can cause overheating on specific phases.

Thermal imaging clearly identifies these imbalances, allowing electricians to redistribute loads and prevent long-term damage.

🔥 Why These Electrical Faults Matter

Most electrical faults develop gradually and remain hidden until failure occurs.

Regular thermal imaging inspections allow electricians to identify problems early and take corrective action before they become serious hazards.

🔧 We Don’t Just Find Faults — We Fix Them

At Atomic Electrical Group, all inspections are carried out by licensed electricians.

This means we can:

✔️ Identify faults accurately
✔️ Perform electrical testing
✔️ Carry out repairs and upgrades

Providing a complete solution from inspection through to rectification.

💰 Preventative Maintenance Saves Money

Fixing small issues early is far more cost-effective than dealing with major failures.

Routine inspections help reduce:

• Emergency call-outs
• Equipment replacement costs
• Business downtime
