Talking about electricians, we refer to people who install and repair the wiring in buildings.
It also includes electrical systems in them, such as HVAC, lighting, security, and computer networking.
Today, electricians work in four main sectors:
- Residential Electricians work on home premises from single-family houses to apartment complexes.
- Commercial Electricians can work on office buildings, hospitals, schools, retail outlets, and industrial facilities that don’t use high voltages.
They install and repair electrical systems of existing commercial buildings as well as new construction and renovation projects.
- Industrial Electricians handle the installation and maintenance of electrical machinery and components in industrial settings.
Their work can include high-voltage electrical systems in industrial manufacturing facilities.
- Low Voltage Electricians work with low-voltage systems that usually include VDV (voice, data, video) systems and networks.
These professionals are also known as VDV electricians.
Primarily, they handle fiber optic cable and phone lines installation and repair in various settings.
Some states combine some of these categories.
For instance, residential and low voltage electricians can fall under the same category.
Other states may put commercial and industrial electricians into one category.
Besides these categories, electricians can be subdivided by the level of training and experience:
These are electricians in training.
They work under the supervision of an experienced professional (journeyman or master) before they can become journeymen themselves.
Electricians become journeymen after they complete the apprenticeship program and are tested by the state-approved authorities to be competent in the trade.
Master electricians have years of experience as a journeyman with a proven high-level experience through a state exam.
A licensing regulatory agency of every state defines the scope of duties and parameters of every level.
Common Tasks and Job Duties Electricians Perform
In general, specific job duties really define what it means to be an electrician.
For example, wiring a house.
While performing large-scale residential wiring projects, electricians should follow the sequence and adhere to certain rules that include safety, code, functionality, and aesthetics:
- Low voltage wiring for voice, data, and cable/video.
- Washer, dryer, and stove, which require independent 220-volt circuits.
- Ground connections on power outlets.
- Lighting – light fixtures, light switches, closet lighting, and outside lighting.
- Power outlets – some state codes require tamper-resistant receptacles (TRRs) that help to prevent children from inserting objects such as paperclips.
- Circuit for a hot water heater.
- GFCI (ground fault circuit interrupters, often shortened to GFI) on outlets/breakers in places where water is common like bathrooms, garages, and outside.
- Breaker box/panel and circuit breakers.
- Electricity for ventilation, air conditioning, and ceiling fans.
- Outside lighting/power.
- Main electrical service connection to the residence – overhead or underground connection.
- Circuit for heating and air conditioner units.
Electricians handle the installation of materials related to each type of wiring system as per their knowledge of electrical theory.
It can include the following concepts:
A Historical Perspective on Electricians
Even though electricity wasn’t used by humans until the 1880s, when the first central power stations appeared, its brute force was understood since ancient times.
Even in mythology, most of the important gods were those who possessed the power of electricity in the form of lightning:
- Thor for Norse mythology.
- Tlaloc for the Aztecs.
- Zeus for the Greeks.
- Raijin for the Shinto in Japan (immortalized as Raiden in the Mortal Kombat video game franchise).
- Indra for the Hindus.
There have been some close attempts to discovering how to make electricity work, but significant steps towards understanding electromagnetism were made only in the 1600s.
The first one to make an in-depth study of static electricity was an English astronomer William Gilbert.
Back then, he found that the best way of creating static electricity was rubbing the cloth against amber.
That introduced word ‘electro’ to English, which is amber in Greek.
Eventually, in 1752, during a thunderstorm, Benjamin Franklin conducted his key-on-the-kite experiment that we all were taught in school.
With a few other important figures, there were major inroads to mastering electricity.
By 1875, the first electricians mounted the first street lighting system in LA, and three years later, in Paris.
Even then, electricians were of somewhat divine nature.
Another noteworthy fact is that until 1884, there was severe competition between the widespread use of AC or DC.
If the invention of the first transformer didn’t take place that year, probably all our houses would be powered by DC today.
Now, everybody takes electricity for granted.
However, that doesn’t reduce the importance of electricians one bit.
The Big Picture: Staying Current in an Evolving Industry
As long as we use electricity, we need electricians.
With that, the duties of electricians are always changing.
The codes are always being revised to stay up-to-date.
For instance, in Portland, Oregon, the code was revised to require all houses built after 2008 to install childproof electrical sockets in which you can’t insert single-pointed objects.
Besides the annual modifications of the code, the industry is evolving all the time too.
Solar energy is gaining popularity, and electricians are required to install and inspect solar panel arrays on roofs.
Also, such tech as fiber optics and LAN are relatively new and require fresh training.
With their training and education, electricians adapt to new situations and work environments.
They can find creative solutions to challenging situations.
You can become familiar with all the latest requirements and regulations through the regulatory agency of your state.
Electricians have to be aware of the changes in:
- Wiring regulations.
- Local code regulations.
- National electrical code regulations.
- Building regulations.
