Switchboard Maintenance & Testing

AS/NZS 3000 and WorkSafe NZ guidelines recommend annual inspections as a minimum for most industrial and commercial switchboards. High-criticality environments such as dairy, food processing, wastewater, and continuous process typically require inspections every 6 months. We tailor maintenance frequency to your site’s operational demands and equipment criticality.

A full inspection covers visual examination, insulation resistance (megger) testing, circuit breaker operation checks, busbar and connection torque checks, and cleaning of enclosures to remove dust, moisture, and contaminants. Where thermographic inspection is required, it is carried out by our certified thermography specialist partners and the results are integrated into your inspection report. We provide full test certification and documentation for audit and insurance purposes.

Yes. We maintain and inspect switchboards regardless of original manufacturer. Our team is experienced across all major LV switchboard platforms including ABB, Simotrol, Logstrup, and Quantum assemblies.

Thermographic (infrared) inspection uses calibrated thermal imaging cameras to detect hot spots, loose connections, and failing components that are invisible to the naked eye. Catching these early prevents unplanned outages, equipment damage, and potential fire risk, typically at a fraction of the cost of reactive repairs. CWS coordinates thermographic inspections through certified thermography specialist partners and integrates their findings into our wider maintenance and reporting programme.

Under the Health and Safety at Work Act 2015, operators have a duty to ensure plant and equipment is safe and without risk to health. While there is no single regulation specifying exact maintenance intervals, WorkSafe NZ and AS/NZS 3000 provide clear guidance. Failure to maintain switchboards can result in enforcement action, insurance complications, and liability exposure following an incident.

Both. We offer structured preventative maintenance programmes tailored to your site’s criticality and budget, as well as one-off compliance inspections, post-fault assessments, and pre-sale condition reports. Nationwide service is available.
