Question 1

What is a switchboard thermal inspection?

Accepted Answer

It is an infrared survey of electrical switchboards and distribution equipment used to identify abnormal heating that may indicate defects, developing failures or elevated risk.

Question 2

Does thermal imaging require power shutdown?

Accepted Answer

In many cases, thermal imaging is most useful under normal load conditions because that is when heat-related issues are most likely to present. Site requirements and safe access arrangements will be discussed before the survey.

Question 3

What types of faults can be detected?

Accepted Answer

Common findings include loose terminations, overloaded circuits, phase imbalance indicators, deteriorating components and localised hot spots associated with high resistance connections.

Question 4

Who carries out the inspection?

Accepted Answer

Surveys are carried out by Level 2 thermographers, with Registered Electrical Inspector Christopher Preston available where a broader electrical compliance or verification context is required.

Question 5

Will a report be provided?

Accepted Answer

Yes. A clear written report is provided with thermal images documenting abnormal findings for maintenance, compliance and insurer records. Good reporting should help the client understand not just what was seen, but what should happen next.

Question 6

How often should switchboards be thermally inspected?

Accepted Answer

Many commercial facilities schedule annual or biennial surveys depending on operating load, risk profile, criticality of the site and insurer requirements.

Question 7

Can this be combined with a Certificate of Verification (COV)?

Accepted Answer

Yes. Where appropriate, switchboard thermal imaging can sit alongside a broader electrical verification process.

Question 8

Do you inspect MCCs and larger panels?

Accepted Answer

Yes. MCCs and larger distribution equipment can be assessed where access, safety conditions and operating load allow.
