Manufacturing plants, food-processing facilities, water-treatment works, and logistics warehouses share a common electrical characteristic: the cost of downtime dwarfs the cost of the electrical system itself. VoltCity Surge's industrial division is staffed by electricians with trade certificates and significant hands-on experience in high-voltage distribution, motor control, PLC I/O wiring, and the industrial cabling standards that govern heavy-load environments across Australia.
Plant and Machinery Wiring
New machinery installations and production-line extensions require cable routes that handle continuous high-current loads, mechanical vibration, chemical exposure, and temperature extremes simultaneously. We size conductors to AS/NZS 3008 for the actual installation method — whether direct-buried, in conduit, on ladder tray, or in a cable management system — accounting for derating factors including grouping, ambient temperature, and thermal insulation. All terminations are torqued to manufacturer specifications and recorded in our commissioning documentation.
Motor Control Centres and Soft Starters
Motor control centres (MCCs) are the nervous system of any process plant. VoltCity Surge designs, builds, and commissions motor control panels from first principles — selecting contactors, overload relays, phase-failure protection, and isolation devices rated for the actual motor full-load current and starting characteristics. Where process demands allow, we specify variable-speed drives (VSDs) to reduce peak demand charges and extend motor service life. All panels are built to AS/NZS 3000 and the switchgear manufacturer's installation instructions, with arc-flash hazard assessments available on request.

PLC and Instrumentation Wiring
Programmable logic controllers and field instrumentation demand wiring practices that differ fundamentally from power circuits. Shielded twisted-pair cabling, segregated cable trays, correct earthing of instrument screens at a single point, and correct signal-cable grounding topologies are non-negotiable for reliable analogue and digital I/O performance. Our industrial team has experience with Siemens S7, Allen-Bradley ControlLogix, Schneider Modicon, and Beckhoff TwinCAT platforms, wiring I/O modules to field instruments, transmitters, and actuators in accordance with the PLC manufacturer's wiring specifications and the relevant Australian instrument standards.
Preventative Maintenance Programmes
Unplanned electrical failures in industrial environments are almost always preceded by detectable warning signs — elevated termination temperatures, increasing insulation resistance degradation, or vibration-induced cable chafing. VoltCity Surge offers structured preventative maintenance programmes that include thermal imaging surveys, insulation resistance testing per AS/NZS 3017, mechanical inspection of cable supports and containment, and detailed condition reports with prioritised defect lists. Programmes are scheduled around your production calendar to minimise impact on output.
Emergency Breakdown Response
When a production line stops, every minute counts. Our 24/7 industrial breakdown response ensures a qualified industrial electrician is mobilised within 90 minutes of your call anywhere in our service coverage area. We maintain a parts inventory of common contactors, fuses, VSD components, and cable materials so that straightforward faults can be rectified in a single attendance. For complex faults, we deploy thermal cameras, power-quality analysers, and oscilloscopes to diagnose root cause before replacing components, preventing the costly cycle of parts-swapping that leaves underlying problems unresolved.
Frequently Asked
Do you work in classified hazardous areas?
Yes. Our industrial electricians are trained in hazardous-area wiring to AS/NZS 60079 and are familiar with Zone 0, 1, and 2 classification requirements. We verify area classification drawings before commencing work, select Ex-rated equipment appropriate to the gas group and temperature class, and complete the required inspection records per AS/NZS 60079.17 at completion.
Can you commission variable-speed drives on our existing motors?
Yes. VSD retrofits require a review of motor insulation class (F or H recommended for VSD duty), bearing current protection (insulated bearings or shaft-grounding rings for larger frames), and supply-cable screening to suppress conducted EMI. We configure drive parameters for the specific motor nameplate data and process requirements, perform a staged run-up under no-load and full-load conditions, and document all settings in the commissioning record.
What is included in a thermal imaging survey?
Our thermal imaging surveys use calibrated FLIR radiometric cameras to scan all accessible switchgear, MCCs, termination boxes, and cable joints under normal operating load. We produce a written report with radiometric images, identified hot spots classified by severity (informational, advisory, or critical), and recommended corrective actions referenced to AS 1860 and IEC TR 60890 practice. Survey reports are suitable for presentation to your insurer.
