In certain situations, when electrical equipment is replaced in high voltage installations or installations within hazardous areas, there might be cases where an accredited auditor isn't required to conduct an inspection before reconnection.
However, if you are responsible for the electrical equipment, it is your legal obligation to ensure that both the equipment and the installation are electrically safe.
Even when an inspection by an accredited auditor is not mandated, the electrical work must be tested to guarantee the safety of the installation.
No audit required:If the replacement of electrical equipment is done with 'like for like' equipment, there is no need for an accredited auditor to inspect the installation. Equipment is considered 'like for like' if:
- The existing circuit wiring can be reconnected to the termination point of the replacement equipment, which is placed in the same position as the replaced unit.
- The electrical rating characteristics are identical, maintaining the maximum demand or rating of the installation.
- The classification ratings remain identical, with no change in the protection level or technique of the equipment.
- The replacement equipment has certification proving compliance with the relevant Australian Standards, whether it's new equipment, second-hand equipment assessed in an accredited workshop, or repaired equipment from an accredited workshop.
Not 'like for like' equipment - audit is required:If the replacement involves equipment with different specifications than the original or requires alteration of the installation wiring for termination, it is not considered a 'like for like' replacement. In such cases, an inspection by an accredited auditor is necessary before reconnection. This ensures that the replacement meets safety standards and doesn't introduce any risks to the electrical installation.
