End-to-end electrical testing solutions
Most generalist contractors treat electrical testing as a rapid, superficial check-box exercise. They plug in a tester, place a pass tag on the cable, and hand over a generic report that lacks deep technical analysis. This superficial approach fails to uncover latent insulation degradation, unbalanced loads, or high-resistance terminations in your switchboards. These unresolved issues represent a silent point of failure that can cause major mechanical damage and sudden, expensive production shutdowns.
MEX Engineering Group provides a complete, end-to-end industrial electrical testing solution. We lead with a maintenance-first reliability mindset, beginning with our customisable Service Level Agreements (SLAs). Our embedded industrial electricians build deep site memory, systematically mapping your switchboards, testing safety PLCs, and checking Low Voltage circuit integrity. We do not just log results; we isolate root causes, execute necessary corrective adjustments during planned shutdown windows, and deliver audit-proof documentation to secure your facility’s operational continuity.
Our Customizable SLA approach
- Client-focused consultation: We meet directly with clients to understand their specific operational needs and challenges.
- Menu-based customization: We build custom packages ‘off a menu’ so you can choose the exact support required.
- Targeted scope: We only include services the client actually wants—no unnecessary add-ons or bloat.
- Tailored pricing: Pricing is tailored accordingly.

Types of industrial electrical testings
Our licensed industrial electricians specialise in the rigorous physical and electrical demands of heavy production. We provide comprehensive electrical testing across a wide range of critical categories, including:
Preventative safety testing
Regular testing of emergency stops, RCDs, safety interlocks, and earthing systems to protect your workforce.
Instrumentation and calibration testing
Testing sensors, control loops, and transducer signals to eliminate mechatronic communication faults.
Switchboard thermal diagnostics
Non-invasive infrared scanning of switchboards, distribution boards, and smart Motor Control Centres (MCCs) under normal operating loads.
Compliance and regulatory audits
Thorough testing and verification of your facility’s Low Voltage electrical installation against AS/NZS 3000 and AS/NZS 3760 standards.

Core Trade Capabilities
Maintenance
Fractional maintenance and 24/7 breakdown support. We protect uptime and stabilise plant reliability by providing customisable service-level agreement.
Electrical
Low Voltage power, control design, and electrical area installations. We provide safe, compliant, and robust electrical systems.
Additive Manufacturing
Industrial Markforged 3D printing. We can do rapid reverse engineering to overcome supply chain delays.
Machine Safety
Full-stack CMSE® safety solutions. Unlike advisory-only consultants, we execute all four stages in-house (risk assessment, safe design, physical installation, and validation) eliminating contractor handoff risk while ensuring complete AS/NZS compliance.
How we saved $17,000 per hour by reducing downtime
Our client’s plastic pallet washing facility is a critical piece of their supply chain infrastructure that runs 24/7. MEX Engineering Group was engaged to provide 24-hour operational assistance and critical preventative maintenance shifts to ensure the plant could survive the severe demands of continuous production.
By embedding a team of three maintenance electricians and one mechanical fitter, we organise all trades, source parts, and execute scheduled preventative repairs over four targeted weekend shifts. Since taking control of the preventative asset care on-site, unplanned downtime has decreased significantly. With client downtime valued at approximately $17,000 per hour, our engineered preventative maintenance strategy delivers considerable, measurable savings across their business operations.
Reliable electrical testing framework
We follow a structured 6-step framework to execute your electrical testing program safely and efficiently:
Site inventory and audit scoping
Detailing your plant’s electrical assets, switchboards, and past fault history to map testing requirements.
SLA maintenance integration
Setting up a customisable Service Level Agreement (SLA) to schedule routine testing and inspections on a fixed monthly budget.
Non-invasive thermal diagnostics
Scanning live electrical assets under normal production loads to catch high-temperature hotspots early.
Scheduled functional testing
Testing RCDs, insulation resistance, and earthing systems during planned shutdown windows to avoid production stops.
Root cause fault isolation
Replacing warm breakers, failing contactors, and worn wiring identified during the testing phase.
Audit-ready compliance reporting
Delivering comprehensive visual records, verified test metrics, and updated as-built drawings.

Frequently Asked Questions
How often should my facility undergo switchboard thermal scanning?
Under Australian Standards and HSEQ best practices, heavy industrial switchboards and Motor Control Centres should undergo non-invasive thermal scanning at least once every twelve months. Facilities operating under high-load, 24/7 rosters often opt for biannual thermal scans as part of their customised SLA to identify high-resistance hot joints before they cause catastrophic damage.
Why do facilities consistently underestimate machine downtime costs?
Many operations managers look only at the direct cost of an electrician’s callout or a replacement part, ignoring the cascading financial losses of idle workers, disrupted downstream supply chains, and missed delivery targets. Unplanned outages from electrical failures can cost tens of thousands of dollars per hour. Regular, structured electrical testing under a predictable SLA is an investment that protects your throughput and secures your cash flow.
How does a Service Level Agreement (SLA) improve our electrical compliance?
Instead of relying on reactive ‘do and charge’ contractors, we formalise your compliance through a subscription-based SLA. We build custom SLAs off a menu to meet your exact needs, with guaranteed response times. Our embedded technicians manage your recurring test logs, thermal scan schedules, and AS/NZS 3000 compliance, eliminating budget volatility and protecting your site from regulatory audits.
Are your electrical maintenance services compliant with Australian Standards?
Yes. Every piece of work we execute is carried out strictly in accordance with AS/NZS 3000 (Wiring Rules), AS/NZS 3008, and NECA-backed safety regulations. Our in-house TÜV Nord-certified CMSE® professionals also ensure safety PLC logic and emergency stop loops are compliant with AS/NZS 4024.
Do you use subcontractors for your electrical maintenance?
No. While we maintain a robust network of industry partners, we deliver our core services using our own highly trained, full-time industrial electricians. This strict in-house engineering capability eliminates contractor handoff risks and ensures that your electrical safety is managed by technicians trained in our own dedicated facility.
