An electrical job in an office might involve lighting, general power or a distribution board. In a factory, the scope can include three-phase machinery, PLC controls, safety circuits and a shutdown window that ends before the next shift starts. For a business owner, builder or property manager, that changes the type of electrician the site needs.
Choosing a contractor with experience that matches the site can affect shutdown planning, equipment commissioning, fault finding and whether production starts when it is supposed to. The domestic, commercial and industrial categories are useful because they show how quickly the electrical scope changes once machinery, controls and plant infrastructure enter the job.
Industrial Vs Commercial Vs Domestic Electricians
In practice, domestic, commercial and industrial are labels used to describe the type of site, equipment and electrical systems involved. They aren’t separate electrician licence classes. The following table gives a practical overview.
| Electrician Type | Typical Sites | Common Electrical Work |
|---|---|---|
| Domestic | Homes, apartments and residential renovations | Lighting, power points, appliances, residential switchboards, safety devices and faults |
| Commercial | Offices, retail, commercial buildings and warehouses | Lighting, distribution boards, HVAC supplies, fit-outs, general power and maintenance |
| Industrial | Factories, production plants, processing facilities, automated warehouses | Machinery, switchboards, three-phase equipment, control cabinets, PLCs, automation and commissioning |
Where The Categories Can Overlap
Real sites don’t always fit neatly into one category. A warehouse can have office lighting and general power in one area, with three-phase motors, pallet conveyors, control cabinets and automated handling equipment elsewhere. If the job is scoped around the building services alone, machinery and controls work can be missed until installation or commissioning.
That overlap is why the site and the actual scope matter more than the label. The contractor needs experience with the electrical infrastructure, controls and operating constraints tied to the equipment.
What Makes Industrial Electrical Work Different?
Industrial electrical contracting usually involves more connected systems, larger plant loads and tighter operational constraints. The electrician may need to work with engineers, fitters, equipment suppliers, automation specialists and production teams before the first cable is installed.
Machinery, Motors & Power Distribution
Factories and processing facilities often have multiple three-phase motors, production machines and larger distribution systems operating across the same site. A new machine may need a dedicated feeder, local isolation, additional protection and changes to an existing switchboard or distribution board.
The electrical scope extends beyond the machine itself. A packaging machine, for example, may arrive with conveyors, sensors and auxiliary equipment that all need power and control connections. If switchboard capacity or cable routes haven’t been checked early, installation can stall after the equipment is already in position.
Controls, PLCs & Automation
Modern industrial equipment often depends on PLCs, HMIs, variable speed drives, sensors, interlocks and control cabinets. These systems need to communicate with the machine and, in many facilities, with surrounding conveyors or existing plant controls.
A missed sensor connection or incorrect interlock can hold up commissioning even when the mechanical installation is complete. Industrial electricians need to understand how power, controls and automation fit together so testing can move through the full operating sequence.
Safety & Compliance Requirements
Electrical installations need to meet applicable safety and compliance requirements. AS/NZS 3000:2018, known as the Wiring Rules, sets technical requirements used to design, construct and verify electrical installations in Australia.
Industrial sites can add further practical requirements. On a food production line, an isolator or enclosure placed in the wrong washdown zone can be harder to clean around or exposed to moisture. In pharmaceutical and other controlled environments, restricted access and incomplete records can hold up testing or handover.
The contractor also needs to plan safe isolation, testing and commissioning around the work being completed. On an operating site, those steps need to fit the site’s own safety procedures and access rules.
Shutdowns & Production Schedules
Industrial electrical work is often planned around a fixed shutdown or maintenance window. Before the outage begins, the team needs to know which circuits will be isolated, where new cabling will run, what equipment needs access and what has to be tested before production restarts.
If a shutdown starts on Saturday morning and a breaker, cable route or control interface hasn’t been confirmed, there may be little room to recover before the next shift. Proper planning lets the team move from isolation to installation, testing and restart within the agreed shutdown window.
Which Type Of Electrician Does Your Project Need?
The easiest way to decide is to look at the site and the systems involved.
Domestic Electrical Work
Domestic electricians commonly handle lighting, power points, appliances, household switchboards, safety devices and faults in homes and apartments.
Commercial Electrical Work
Commercial electricians work across offices, retail sites, warehouses and other business properties. Common work includes lighting, general power, distribution boards, HVAC supplies and fit-outs, often scheduled around trading hours, tenants or building access.
Industrial Electrical Work
Industrial electricians work around machinery, mains cabling, switchboards, motors, PLCs, control cabinets and automation. A single project can involve power, controls and commissioning across several connected systems.
If the work affects production equipment, plant controls or wider site infrastructure, relevant industrial experience becomes important early in the planning process.
Industrial Electricians You Can Trust
Jarlam Electrics is based in Bayswater North and supports industrial electrical projects across Melbourne. Businesses looking for a local electrician in Melbourne may need very different capabilities depending on the site. Plant maintenance, breakdown support, machinery installation and wider upgrades all benefit from a team that already understands industrial operating conditions.
Jarlam Electrics handles industrial electrical contracting across main switchboards, mains cabling, machinery connections, controls and automation. Local electrician services can also cover general power, servicing, installations and commissioning support for industrial facilities.

Industrial Electrician Frequently Asked Questions
What Is The Difference Between A Commercial And Industrial Electrician?
Commercial electricians commonly work in offices, retail sites, warehouses and other business properties. Industrial electricians work with factories, processing facilities, machinery, motors, control systems, automation and larger plant electrical infrastructure.
Do Industrial Electricians Work On Machinery And Automation?
Yes. Industrial electrical work can include machinery connections, motors, variable speed drives, PLCs, HMIs, sensors, control cabinets, safety circuits, testing and commissioning. The exact scope depends on the equipment and the site’s existing electrical system.
What Type Of Electrician Do I Need For A Factory?
A factory will usually need an electrician with industrial experience when the work involves machinery, production lines, three-phase equipment, switchboards, controls or automation. Smaller general electrical tasks may have a simpler scope. The contractor still needs to understand the site’s access and safety requirements.
