Industrial facilities run on power that never compromises. A single unplanned outage on a production line can cost tens of thousands of dollars per hour in lost throughput, scrapped product and idle labour. Ironclad Electrical has been engineering heavy-duty three-phase electrical systems for manufacturers, food processors, logistics hubs, mining contractors and heavy fabricators since 2004. We understand the operational pressures of continuous production environments, and we structure every installation to meet them.
Three-Phase Infrastructure Engineered for Load
All industrial installations are designed to AS/NZS 3000 Wiring Rules and AS/NZS 3008 cable sizing standards. We size conductors for worst-case continuous current, voltage drop limits and prospective short-circuit fault current at every distribution point. Our switchgear selections are rated to the actual fault level at the point of supply, not the cheapest box that fits the load. Motor control centres (MCCs) are configured with correctly rated miniature circuit breakers, overload relays and contactor assemblies. Where variable speed is required, we commission variable speed drives (VSDs) appropriate to the motor frame, load type and harmonic environment. On sites where harmonic distortion is a concern, we specify passive or active harmonic filters to keep total harmonic distortion (THD) within acceptable limits and protect sensitive downstream equipment.
Automation, PLC and SCADA Integration
Modern industrial electrical work is inseparable from control and automation. Ironclad Electrical integrates electrical infrastructure with PLC and SCADA systems, handling field device wiring, I/O terminations, instrumentation cabling, earthing schemes for signal integrity, and loop testing to P&ID documentation. We commission motor starters, soft-starters and VSD networks under the direction of process engineers, and we document as-built drawings that remain accurate after the job is done. Our team is experienced with Allen-Bradley, Siemens, Schneider Electric and Omron control hardware.

Arc Flash Safety and Compliance
Arc flash is a real and legally significant hazard in any industrial electrical environment operating above 50V AC. Ironclad Electrical carries out arc flash hazard assessments, calculates incident energy at each switchboard and distribution point, and applies labelling that complies with the guidance in AS/NZS 4836 and Safe Work Australia guidelines. We coordinate protection settings to reduce clearing time, which directly lowers incident energy and the personal protective equipment (PPE) category required by workers at that equipment. Where protection coordination studies are required, we engage an RPEQ-registered power systems engineer and deliver the study documentation as part of the project handover pack.
Project Delivery Without the Drama
Every industrial electrical project is delivered with formal as-built documentation, test and inspection records, Certificate of Test (CoT) under Queensland or relevant state electrical safety legislation, and a handover briefing for your maintenance team. We schedule shutdown work around your production calendar, coordinate with your safety team for permits to work, and staff the job with licensed A-Grade electricians throughout. Ironclad holds full public liability and professional indemnity insurance, and our Master Electricians membership provides independent quality assurance.
