Types of an Electrician

Electrician Delray Beach specializes in a variety of fields. Depending on the type of electrician, responsibilities and training vary.


Residential electricians are responsible for installing wiring, outlets, and fixtures in homes and apartments. They also repair and maintain these systems.

Outside linemen, or line electrical workers, work on utility distribution systems with higher voltages. They are trained to climb power lines and other structures.

A residential electrician is certified to install and repair electrical wiring and other devices for homes and apartments. They work closely with homeowners to understand their needs and help them find solutions that meet those needs safely. Residential electricians are also required to abide by local and state building regulations.

Typically, a high school diploma or GED certificate is necessary to become a residential electrician. Prospective candidates then must complete an apprenticeship to gain hands-on experience in the field and learn the skills of the trade. In addition to classroom time and on-the-job training, prospective residential electricians must pass a state exam to become licensed.

Residential electricians are often responsible for installing lighting fixtures, outlets and switches. They can also perform home renovation projects and provide maintenance and repairs to existing electrical systems. They must be able to read blueprints and technical drawings, examine electrical components and troubleshoot problems. They may be employed by an electric company or may choose to run their own business to work independently.

When working in a home, a residential electrician must consider the number of outlets, circuits and devices that need to be wired together. They can also be expected to install a variety of other devices such as generators, appliances, smoke alarms and more. They must also be knowledgeable about the latest electrical devices and their requirements. For example, electric cars are now popular and require a special type of feeder to power them up.


Electricians who work in a commercial setting are called on to install, inspect, repair and maintain electrical devices and power systems within buildings and other business types. Their duties include determining the safest and most efficient way to run wiring through a building, reading blueprints and deciding where to place electrical equipment. They may also be responsible for repairing faulty wires, fuse boxes and general customer troubleshooting.

One of the most significant differences between this type of electrician and residential electricians is that they often work with larger voltage levels in a commercial setting. This is because business equipment and machines require higher power loads than household appliances. It also means that commercial electricians must have a more in-depth knowledge of power distribution and three-phase systems.

The other major difference is that while residential electricians must take care to ensure that their work abides by local safety regulations, commercial electricians are often required to be familiar with more complex automated machinery. This means that they will be tasked with installing, maintaining and repairing security systems, workplace water heaters, office fire alarms and other essential equipment that keeps the business running smoothly. They are also frequently required to climb ladders and remain in uncomfortable positions for long periods of time. These are just some of the many reasons why it’s important to hire an electrician who is highly trained and experienced.


Industrial electricians are tasked with working with machinery electrical systems in industrial settings like factories and power plants. They typically work with three-phase power, which has a higher voltage than the single-phase power used in homes. These professionals are responsible for installing, repairing, and maintaining equipment in industrial settings, such as power plants, processing plants, and manufacturing facilities.

Industrial Electricians often work with large, complex machinery and are required to have a high level of knowledge of the National Electrical Code. They also often work with maintenance supervisors and managers to ensure that electrical systems are working properly.

Installation electricians are responsible for the wiring of new construction projects. They set up the wiring for lighting, heating and cooling, and security systems. They may also assist interior wiremen, who handle the lower voltage cabling that is utilized within buildings. Installation electricians frequently work in both indoor and outdoor settings and must be prepared to work in confined spaces or on ladders.

A lineman is an outdoor-based electrician who is in charge of power-line distribution, which requires them to undergo comprehensive safety training that includes climbing school and ongoing training for high-angle rescues should a coworker fall on the job. They are responsible for on-premises electrical wiring and distribution, as well as assisting inside wiremen with the lower-voltage cabling that is utilized in building interiors, such as phone, video, and data outlets.


All water-faring vessels have electrical systems that require installation, maintenance and repair. A person who works on these types of devices is referred to as a marine electrician. They are trained at specialized trade and seamanship schools and work on boats, ships and yachts.

The duties of a marine electrician involve understanding diagrams and blueprints, responding to customer complaints and concerns, inspecting electrical equipment, repairing and replacing wiring, locating problems, handling outlets and switches, and maintaining an active communication line with other crew members. They must be able to safely board any vessel.

A marine electrician is also expected to be skilled in using tools such as multimeters, voltmeters, and ohmmeters to test circuitry and equipment. They typically work with tinned, stranded wire that is more flexible and resistant to corrosion than solid copper wire and crimped connections that are less likely to break than soldered ones.


Electricians who work in a maintenance setting are responsible for inspecting, monitoring and repairing electrical systems within commercial buildings, including offices and workplaces. They may also assist in planning and designing electrical systems during new building construction. These professionals must be able to navigate local electrical codes and public safety concerns.

Employers often ask about an electrician’s experience with energy management and automation technologies like lighting controls, sensors, and smart grid systems. They want to see if you have an understanding of how these systems function and how they can improve a company’s efficiency and cost-saving measures.

Lastly, interviewers may inquire about an electrician’s familiarity with different power distribution methods. For example, they may ask about your knowledge of single-phase and three-phase power systems, which are two of the most common ways electricity is transmitted to buildings.

Electricians need to have a strong understanding of mathematical and scientific principles as they work with power systems, circuits, and components. They also need to have good comprehension skills to be able to read and understand memos, blueprints, and technical documents they receive on new job sites. Finally, electricians should have keen eyesight and hand-eye coordination to be able to perform their duties effectively.


An electrician who works in an installation setting typically focuses on building or upgrading electrical systems. They may install wiring for smart devices, entertainment systems, telecommunications equipment and more. Their duties also include reading blueprints and planning out the safest and most efficient way to route and place wiring throughout buildings. They also know the right tools for each job and how to use them properly.

This category also includes service electricians who work on specific requests for rewiring and repairs, as well as construction electricians who are responsible for large-scale electrical projects like new buildings or remodels. Some electricians who specialize in this area will even go on to become project managers, supervisors or estimators.

Another specialization is the residential wireman, who, much like the name suggests, is tasked with connecting a client’s electrical equipment to the power source. The similarities end there, however, as these electricians also perform other types of home installations and must stay abreast of technological developments in the household sector. Finally, the outside lineman, or lineworker, is an electrician who works on power line transmissions and distribution systems, often working outdoors in challenging weather conditions.
