Electrical Safety Audits in Melbourne
ARA Electrical Services delivers electrical safety audits across Melbourne for industrial and commercial installations, with a focus on compliance with AS/NZS 3000 (Wiring Rules) and the safe, reliable operation of switchboards, MDBs, MCCs, and associated distribution systems.
Audits are carried out by experienced electrical engineers and industrial electricians with a background in industrial installations. That combination ensures findings reflect both the requirements of the relevant standards and how the installation actually operates under load — not just how it appears on the day of inspection.
Electrical safety audits in Melbourne are not approached as checklist exercises. They are structured to identify non-compliances, degraded installation conditions, and system-level risks that directly affect safety, reliability, and ongoing operation.
AS/NZS 3000 Compliance Assessment
Audits are completed against the requirements of AS/NZS 3000, with focus on the areas that most commonly present risk in industrial and commercial environments. This includes assessment of:
- Switchboard construction, configuration, and compliance
- Protection device selection, ratings, and installation
- Cable sizing, protection, and installation methods
- Earthing systems and equipotential bonding
- Segregation of circuits and wiring systems
- Final subcircuit installation and associated protective devices
Particular attention is given to how the installation has changed over time — including additions, modifications, and temporary works that may no longer align with current standards or the original design intent.
Switchboard, MDB, and MCC Assessment
Switchboards, MDBs, and MCCs are assessed as critical components of the electrical installation, evaluated for both compliance and actual operational condition. This includes review of:
- Physical condition of boards, enclosures, and internal structure
- Adequacy of circuit segregation and separation between functional units
- Access arrangements, clearances, and safe working conditions
- Circuit identification, labelling, and documentation accuracy
- Condition of busbar systems, connections, and terminations
- Evidence of overheating, physical damage, or deterioration
Where applicable, audits also consider alignment with AS/NZS 61439 — particularly where switchboards have been modified, extended, or no longer reflect original assembly verification requirements.
Protection Systems and Fault Performance
Protection systems are reviewed to confirm correct application, appropriate device selection, and coordination across the installation. This includes:
- Circuit breaker and protective device selection against available fault current
- Evidence of non-compliant or incorrectly applied protection arrangements
- Coordination and discrimination between upstream and downstream protective devices
- Condition and operability of protective devices in service
Audits identify situations where protection systems may not operate as intended under fault conditions — including risks from nuisance tripping, lack of selectivity, or inadequate fault level protection that could expose equipment and personnel to unnecessary risk.
Earthing, Bonding, and Fault Path Integrity
Earthing and bonding systems are assessed to confirm the integrity of fault current paths and compliance with AS/NZS 3000 requirements. This includes:
- Main earthing system configuration and continuity
- Bonding of metallic services, structures, and plant
- Continuity of protective earthing conductors throughout the installation
- Condition of earth connections, joints, and terminations
- Identification of missing, inadequate, or degraded bonding
Earthing and bonding integrity is critical to ensuring protective devices operate correctly and that safe disconnection of supply under fault conditions is achieved reliably.
Findings Assessment and Rectification Pathways
Audit findings are reviewed against AS/NZS 3000 and associated standards, with non-compliances assessed for their impact on safety, system integrity, and ongoing operation.
Findings are not treated in isolation. Each issue is analysed in context — how the system is loaded, how it has been modified, how it is currently operated, and how individual non-compliances interact with each other. This ensures recommendations are practical and site-specific rather than generic compliance advice that does not account for real operating constraints.
Audit reports are delivered through ARA’s in-house reporting system by our electrical auditors in Melbourne, providing clients with clear visibility of identified risks and required actions. Each report includes:
- Risk matrix classification of all findings
- Defect prioritisation based on severity and likelihood of consequence
- Recommended rectification actions aligned with Australian Standards
- Indicative cost guidance to support budgeting and maintenance planning
Where required, ARA Electrical Services can support the full rectification process — from design review through to implementation — ensuring works are completed in line with audit findings and the requirements of the relevant standards.
