The Different Types of Electricians and Electrical Services

Electricity is a valuable thing to have in every home and business, and electrical works are what make the comforts, products, and services that modern life has to offer much more available to us. The electrician installs and maintains the systems that provide power into the machinery and equipment that makes almost everything available to us, and this is what makes the electrician so important, especially in Singapore.

Electricians also have their own specializations in different types of electrical works. There are at least three main areas where these specialties are applied, which are:


This term is mostly applied for electrical necessities that occur in households, which include installation and repair/maintenance of things such as wirings, power outlets, circuit breakers, and the house’s power meter or connection to the domestic power grid in Singapore.


Commercial electrician services include, but may not be limited to the installation and/or repair of power systems in commercial establishments, such as office buildings and malls, that require a significant amount of power in order to perform their daily business.

With that said, there are some similarities between commercial and domestic electrician services provided by companies like power max in Singapore in that they essentially work in a similar manner except for the size.

From air-conditioning to lighting, to power outlets for computers and other types of office equipment, business’ power systems need to be updated to be able to accommodate the kind of power requirements as well as maximize productivity with the minimization of potential power interruptions caused by faulty wiring.


A good electrician is an especially valuable asset to industrial sectors that require large amounts of power and current in their systems in order to operate various types of equipment and machines that go into the manufacturing of products and services.

Types of Electricians

Apart from the different fields where electricians can apply their skills, there are also three stages or types of electricians working in these said fields, either working to complete their training or to supervise and train those who they are working with.

These three categories of electricians can be classified into apprentices, journeymen, and master electricians. Here they are explained in detail:

• Apprentice – Apprentices are electricians in training who are working their way to their certification to become a journeyman, and often work with close supervision from their higher-ups, who can either be journeymen or master electricians.

• Journeymen – Journeymen electricians work mostly with mechanical connections, installations, and power supplies in both residences and commercial buildings, as well as overhead lines. These types of electricians can be found in construction firms, utility companies, or manufacturing plants.

After passing their apprenticeship and their electrical exam, journeymen receive a certification as a licensed electrician. They can then proceed to work on any type of system unsupervised. They can also train apprentices who are working towards a certification.

• Master Electrician – Master electricians like from Singapore are highly skilled tradesmen usually found working in supervisory roles for major companies or working as a licensed electrician in their own contracting business. These types of electricians have already completed their apprenticeship and earned their bachelor’s degree as well as their certification as master electricians.

Aside from the minimum necessary experience training, master electricians also need to possess managerial skills in order to supervise laborers, apprentices, and journeymen on either residential or commercial jobs.

Electrical Services

Different electrical servicing companies offer different types of electrician services, which can depend based on whether the electrical servicing company is working in the domestic, commercial, or industrial sector.

• Electrical troubleshooting – A licensed electrician employed by the company will be sent over to your building in order to inspect your power systems and find the cause of your power failure.

When it comes to electrical troubleshooting, the electrician will not only determine the cause of your power failure, but also take into account the necessary repairs and upgrades to make in order to keep your power systems operating smoothly. This is usually done with the aid of both the electrician’s tools, training, and experience.

• Short circuit repairs – A short circuit can occur when an active wire and an inactive wire touch each other. A lot of current then flows from the active wire to the inactive one, resulting in either a blown fuse or a tripped circuit breaker.

• Circuit breaker replacement – A tripped circuit breaker can either be the result of a short circuit or a ground fault, which in turn could result in a temporary power outage for that particular line as a safety measure to avoid overloading.

• Upgraded wiring/Rewiring – Wires can deteriorate under harsh conditions or be stripped of their insulation, which can cause a potential electrical or fire hazard. When this happens, the existing wiring should be replaced with new ones.

Electricians can also re-wire existing lines from old to new service connections, connect and disconnect wirings depending on the usage, or re-route certain wirings to make sure that they do not pose as a potential hazard.

• Electrical extensions – Wiring can either be too short or too stretched out to provide a reliable power connection, which could result in the wire posing as a potential hazard. This is because stretched-out wiring is more prone to snapping especially under strong winds and bad weather.

Electrical extension adds an extra length to the existing wiring. This gives it an allowance of space and minimizes any potential for being an electrical or fire hazard.
