Delivered by Best-in-Class Technicians for 20 Years
For over 20 years, MEX Engineering Group has operated as the critical infrastructure partner for some of Australia’s most demanding manufacturing and processing environments. We deliver every project under strict HSEQ risk discipline, ensuring safe, compliant, and right-first-time engineering execution.
Unlike other engineering firms who rely on transient labour, we invest heavily in our dedicated in-house training centre to develop the most skilled industrial electricians and mechanical fitters in the industry. This guarantees stable site teams, deep institutional memory, and unparalleled workmanship for your plant. MEX Engineering Group is a CMSE® (Certified Machinery Safety Expert – TÜV NORD) and houses the NSW Centre of Excellence for Additive Manufacturing.

End-to-end electrical design solutions
Many generalist engineering firms treat electrical design as an isolated, theoretical software exercise. They produce abstract CAD schematics in clean offices but fail to account for the physical realities of a harsh, high-speed plant floor. This disjointed approach results in poor panel layouts, severe contractor handoff risks, and unsafe workarounds that fail SafeWork audits.
MEX Engineering Group provides a complete, end-to-end solution for industrial electrical design. We lead with a maintenance-first reliability mindset, meaning we design systems with future maintainability, cable access, and thermal dissipation in mind. By mapping out your power distribution, Motor Control Centres (MCCs), and control system architectures, we eliminate single points of failure. Our in-house tradespeople physically construct, install, and commission the panels, completely eliminating contractor handoff risk and ensuring robust performance under heavy industrial loads.
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.
Categories of industrial electrical design
Our engineering team specialises in the complex physical and electrical environments of heavy industry. We provide custom design solutions across several critical categories, including:
Custom control panels
Specifying and designing PLC enclosures, safety relay panels, and human-machine interface (HMI) enclosures.
Low Voltage power reticulation
Designing main switchboard integrations, sub-distribution boards, and heavy-duty busbar systems.
Motor Control Centres (MCC)
Engineering smart MCCs with variable speed drives (VSDs) and soft starters for precise machinery control.
Instrumentation and data loops
Designing process loops, instrumentation shielding, and communication cabling (Ethernet, Profinet, or Modbus) to withstand electromagnetic interference.
Trusted by Australia’s Leading Manufacturers
MEX Engineering Group provides embedded site teams and engineering services to some of the country’s largest production facilities. We maintain critical infrastructure for industry leaders across FMCG, food and beverage, and high-speed packaging, including Tooheys, CHEP, Ullrich Aluminium, Goodman Fielder, and BlueScope Steel.
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 design framework
We follow a structured 6-step framework to transition your electrical requirements from initial concept to safe, live plant integration:
Site capacity & audit assessment
Analysing your existing electrical load profiles, switchboard capacities, and safety risks.
Engineering & schematic design
Draft clean, detailed electrical schematics in CAD, specifying all Low Voltage protection and control loops.
Client design reviewy
Presenting the proposed design and bill of materials to your team for operational alignment.
In-house panel assembly
Constructing custom Motor Control Centres and PLC panels inside our clean workshop.
Turnkey site installation
Deploying our in-house industrial electricians to safely wire, cable, and integrate the new systems during your planned shutdown windows.
Commissioning & validation
Testing every circuit, conducting RCD verification, and delivering full as-built documentation.

Frequently Asked Questions
How does a Service Level Agreement (SLA) support our electrical infrastructure?
Historically, emergency electrical response has relied on informal, reactive phone calls, which exposes plants to unpredictable costs and delays. We solve this by formalising our support into Service Level Agreements (SLAs). Instead of dealing with the constant friction of ‘do and charge’ billing, an SLA secures technical priority and dedicated resource planning for a predictable, fixed monthly fee. We build custom SLAs off a menu to meet your exact needs with guaranteed response times.
Is additive manufacturing or custom 3D printing included in the SLA?
No. Our advanced additive manufacturing and industrial 3D printing capabilities (operated out of our dedicated NSW Centre of Excellence) are treated strictly as an add-on service. If a custom bracket or custom PLC mounting jig is required, we reverse-engineer and print it utilising Onyx® composite material or the suitable metal required on Markforged platforms, priced separately off a dedicated menu of engineering capabilities.
How do you calculate the return on investment for an electrical design upgrade?
Many facilities consistently underestimate the true cost of their machine downtime, looking only at the immediate repair bill. An outdated electrical system causes cascading losses, including idle operator wages, supply chain disruptions, and missed delivery targets. By investing in modern CAD-designed power distribution and smart Motor Control Centres, you eliminate single points of failure, protect your throughput, and secure your long-term cash flow.
Are your electrical designs fully compliant with Australian Standards?
Yes. Every electrical layout we produce is engineered to strictly comply with AS/NZS 3000 (Wiring Rules), AS/NZS 3008 (Conductive Sizing), 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.
