Residential vs Commercial vs Industrial Electrician: What’s the Difference?

Not all sparkies do the same thing.

An electrician wiring new houses can have a very different working day from someone maintaining machinery in a factory or installing electrical systems on a major commercial construction project.

Three of the biggest areas are residential, commercial and industrial electrical work.

The basic electrical qualification may provide the foundation, but the equipment, workplaces, skills and career opportunities can become quite different as you gain experience.

So what's the difference, and which type of electrical work might suit you?

Residential Electricians

Residential electricians primarily work in houses, apartments and other residential properties.

It's the electrical work most people are familiar with.

A residential electrician might spend the day installing power and lighting in a new house, completing a switchboard upgrade or trying to work out why someone's circuit breaker keeps tripping.

Common residential electrical work can include:

• New home wiring
• Renovations
• Power points
• Lighting
• Ceiling fans
• Switchboards
• Smoke alarms
• Fault finding
• Electrical repairs
• General maintenance
• Outdoor electrical installations

Residential electricians can work directly for electrical contractors or eventually operate their own contracting businesses once they meet the relevant licensing requirements.

What's Residential Electrical Work Like?

Variety is one of the biggest features.

A service electrician might visit several different properties in a single day, while someone working on new construction could spend weeks moving between houses on the same development.

You'll often work closely with builders, carpenters, plumbers and other trades.

There can also be plenty of customer interaction.

If you're doing service work, you'll regularly need to speak with homeowners, explain problems and discuss what needs to be repaired or replaced.

That means communication skills can be almost as important as knowing how to use your tools.

Advantages of Residential Electrical Work

Residential work can be a good option if you like variety and eventually want to run your own business.

Potential advantages include:

• Plenty of different jobs
• Opportunities to work for smaller businesses
• Direct customer interaction
• A pathway towards self-employment
• Work available across Australia
• Experience with new construction and maintenance

You also aren't tied to areas with major industrial facilities or large construction projects.

People need electricians wherever people have houses.

Downsides of Residential Electrical Work

Residential electrical work has its less glamorous moments.

Roof spaces can be hot, cramped and unpleasant. Crawling underneath houses isn't everyone's idea of a great Tuesday.

Service work also means dealing directly with customers, travelling between jobs and sometimes working in occupied homes.

If you'd rather work on large technical systems than spend your career installing downlights, another area of electrical might appeal more.

Commercial Electricians

Commercial electricians generally work on larger buildings and developments.

This can include:

• Offices
• Retail stores
• Shopping centres
• Schools
• Warehouses
• Restaurants
• Hotels
• Apartment developments
• Healthcare facilities
• Large construction projects

The scale of the electrical systems is generally larger than what you'd encounter in a house.

Commercial electricians can work on both new construction and existing buildings.

What Does a Commercial Electrician Do?

Commercial electrical work can involve:

• Installing electrical cabling
• Cable tray and support systems
• Distribution boards
• Lighting systems
• Emergency lighting
• Power distribution
• Equipment connections
• Testing and commissioning
• Maintenance
• Fault finding
• Office and retail fit-outs

On major construction projects, commercial electricians can spend months or even years working on the same development.

You'll usually be part of a much larger team than you'd find in residential service work.

What's Commercial Electrical Work Like?

Commercial construction can be busy.

There may be dozens or hundreds of workers on site, with multiple trades trying to complete their work according to the same construction program.

Coordination matters.

Electrical work may need to happen before walls are closed, after other services have been installed or alongside mechanical and fire systems.

Commercial electricians therefore spend plenty of time working around other trades and following construction drawings and project schedules.

Advantages of Commercial Electrical Work

Potential benefits include:

• Experience on larger electrical systems
• Major construction projects
• Working as part of larger teams
• Opportunities for overtime
• Potential site allowances
• Pathways into supervision
• Exposure to complex installations

Commercial construction can also provide a stepping stone towards major infrastructure and industrial projects.

Downsides of Commercial Electrical Work

Large construction sites aren't for everyone.

They can involve early starts, repetitive work during certain stages of a project and plenty of rules and site procedures.

Your commute can also change whenever the project changes.

One year you might have a job ten minutes from home. The next project could be on the opposite side of the city.

Construction activity can also rise and fall depending on the economy and the amount of development underway.

Industrial Electricians

Industrial electrical work tends to be the most technically specialised of the three.

Industrial electricians work around electrical systems and equipment used in manufacturing, processing and heavy industry.

Typical workplaces can include:

• Factories
• Manufacturing plants
• Processing facilities
• Food production
• Utilities
• Automated warehouses
• Heavy industry
• Mining operations

Rather than primarily dealing with lights and power points, industrial electricians can spend much more time around machinery and control equipment.

What Does an Industrial Electrician Do?

Industrial electrical work can involve:

• Electric motors
• Machinery
• Control systems
• Sensors
• Motor control equipment
• Pumps
• Variable speed drives
• Automated equipment
• Electrical distribution
• Fault finding
• Preventative maintenance
• Plant shutdowns

Some industrial electricians develop additional knowledge in automation, instrumentation or control systems.

That technical experience can become extremely valuable.

Fault Finding in Industrial Electrical

Fault finding is a major part of many industrial jobs.

Imagine a production line suddenly stops.

The company might be losing thousands of dollars every hour the machinery isn't operating.

Someone needs to determine what's gone wrong.

An experienced industrial electrician may need to inspect the system, take measurements, interpret diagrams, test equipment and logically work through potential faults until they identify the problem.

That's very different from simply installing a new electrical system according to a plan.

If you enjoy troubleshooting and figuring out how things work, industrial electrical can be particularly interesting.

Advantages of Industrial Electrical Work

Potential advantages include:

• More technical electrical work
• Valuable specialised experience
• Strong fault-finding skills
• Opportunities in manufacturing and mining
• Potential shift and overtime earnings
• Pathways into automation and controls
• Maintenance careers with permanent workplaces

Experienced industrial electricians can become highly valuable because it takes time to develop strong troubleshooting skills.

Downsides of Industrial Electrical Work

Industrial facilities can be noisy, dirty, hot or operating around the clock.

Depending on the workplace, you could be required to work:

• Night shifts
• Weekends
• On-call
• Overtime
• Shutdowns
• Rotating rosters

Some people love shift work.

Others would much rather be finished by mid-afternoon every day.

Which Type of Electrician Gets Paid the Most?

There isn't a simple rule that industrial electricians always earn more than commercial electricians, or commercial electricians always earn more than residential electricians.

Pay depends on much more than the label attached to the job.

Factors can include:

• Experience
• Employer
• Location
• Industry
• Enterprise agreements
• Overtime
• Shift work
• Penalty rates
• Allowances
• Specialised skills
• Supervisory responsibilities

Industrial and major commercial environments can provide access to attractive wages because of specialised skills, overtime, shift work and project conditions.

Mining and remote industrial electrical jobs can push earnings higher again.

On the other hand, a successful residential electrical contractor running their own business may earn considerably more than an employed electrician.

There are good earning opportunities across all three.

Which Is Best for Starting Your Own Business?

Residential electrical probably provides the most obvious pathway.

There are millions of homes requiring electrical repairs, renovations, maintenance and upgrades.

A residential electrical contractor can start relatively small and build a customer base over time.

Commercial contracting is also possible, but larger projects can require more employees, equipment, working capital and administration.

Industrial contracting can be even more specialised and may require established relationships, experience and additional capabilities.

If owning a small electrical business is your long-term goal, getting plenty of residential and light commercial experience can be particularly useful.

Which Is Best for FIFO and Mining?

Industrial experience can be highly valuable if mining is where you eventually want to end up.

Mining operations rely on enormous amounts of electrical equipment, including processing plants, pumps, motors, conveyors and other machinery.

That doesn't mean residential or commercial electricians can never move into mining.

But having relevant industrial experience can make the transition easier for certain roles.

Which Is Best for Apprentices?

There's no universally "best" electrical apprenticeship.

The quality of the employer and the experience they give you matters enormously.

A good apprenticeship should expose you to useful electrical work and allow you to develop your skills as you progress.

Some apprentices are lucky enough to work for businesses covering several areas.

You might get experience in residential construction, commercial projects, maintenance and fault finding during the same apprenticeship.

That broad exposure can be incredibly useful when you're starting your career.

Can You Change From Residential to Industrial Electrical?

Yes.

Qualifying as an electrician doesn't lock you into the first part of the industry you work in forever.

However, changing areas can require some adjustment.

An electrician who has spent ten years wiring houses won't automatically have ten years of experience diagnosing industrial machinery.

You may need to learn new equipment, systems and working practices.

The earlier you gain exposure to different types of electrical work, the easier it can be to work out what you actually enjoy.

Residential vs Commercial vs Industrial: Quick Comparison

Residential electrical is centred around houses and apartments. It can offer plenty of variety, customer interaction and a strong pathway towards starting your own contracting business.

Commercial electrical involves larger buildings and construction projects. You'll generally work with bigger electrical systems and larger teams.

Industrial electrical focuses more heavily on machinery, equipment, maintenance and fault finding. It can become highly technical and lead towards specialised areas such as automation and mining.

None is automatically better than the others.

They're simply different versions of the same trade.

How Do You Choose?

If you're an apprentice, you don't necessarily need to decide immediately.

Getting broad experience early in your career can be a good thing.

Over time, you'll work out which parts of electrical you enjoy and which ones you'd happily never do again.

You might love dealing with customers and eventually want your own residential business.

You might prefer working on major commercial projects with a large crew.

Or you might discover that spending three hours diagnosing a machine fault is far more interesting than wiring another house.

One of the biggest advantages of becoming an electrician is that you have options.
