Electricians install and maintain electrical systems in homes, businesses, and factories.

Electricians typically do the following:

• Read blueprints or technical diagrams before doing work
• Install and maintain wiring and lighting systems
• Inspect electrical components, such as transformers and circuit breakers
• Identify electrical problems with a variety of testing devices
• Repair or replace wiring, equipment, or fixtures using hand tools and power tools
• Follow state and local building regulations based on the National Electric Code
• Direct and train workers to install, maintain, or repair electrical wiring or equipment

Almost every building has an electrical system that is installed during construction and maintained after that. Electricians do both the installing and maintaining of electrical systems.

Installing electrical systems is less complicated than maintaining older equipment. This is because it is easier to get to electrical wiring during construction. Maintaining older equipment, however, involves identifying problems and repairing malfunctioning equipment that is sometimes difficult to reach. Electricians doing maintenance work may need to fix or replace outlets, circuit breakers, motors, or robotic control systems.

Electricians read blueprints, which are technical diagrams of electrical systems that show the location of circuits, outlets, and other equipment. They use different types of hand and power tools, such as pipe benders, to run and protect wiring. Other commonly used hand and power tools include screwdrivers, wire strippers, drills, and saws. While troubleshooting, electricians also may use ammeters, voltmeters, and multimeters to find problems and ensure that components are working properly.

Many electricians work independently, but sometimes they collaborate with others. For example, experienced electricians may work with building engineers and architects to help design electrical systems in new construction. Some electricians also may consult with other construction specialists, such as elevator installers and heating and air conditioning workers, to help install or maintain electrical or power systems. At larger companies, electricians are more likely to work as part of a crew; they may direct helpers and apprentices to complete jobs.

The following are examples of occupational specialties:

Inside electricians maintain and repair large motors, equipment, and control systems in businesses and factories. They use their knowledge of electrical systems to help these facilities run safely and efficiently. Some also install the wiring for businesses and factories that are being built. To minimize equipment failure, inside electricians often perform scheduled maintenance.   

Residential electricians install wiring and troubleshoot electrical problems in peoples' homes. Those who work in new-home construction install outlets and provide access to power where needed. Those who work in maintenance and remodeling repair and replace faulty equipment. For example, if a circuit breaker is tripped, electricians determine the reason and fix it.

Construction managers plan, coordinate, budget, and supervise construction projects from early development to completion.

Construction managers typically do the following:

• Prepare and negotiate cost estimates, budgets, and work timetables
• Select appropriate construction methods and strategies
• Interpret and explain contracts and technical information to workers and other professionals
• Report on work progress and budget matters to clients
• Collaborate with architects, engineers, and other construction and building specialists
• Instruct and supervise construction personnel and activities onsite
• Respond to work delays and other problems and emergencies
• Select, hire, and instruct laborers and subcontractors  
• Comply with legal requirements, building and safety codes, and other regulations

Construction managers, often called general contractors or project managers, coordinate and supervise a wide variety of projects, including the building of all types of residential, commercial, and industrial structures, roads, bridges, powerplants, schools, and hospitals. They oversee specialized contractors and other personnel. Construction managers schedule and coordinate all design and construction processes to ensure a productive and safe work environment. They also make sure jobs are completed on time and on budget with the right amount of tools, equipment, and materials. Many managers also are responsible for obtaining necessary permits and licenses. They are often responsible for multiple projects at a time.

Construction managers work closely with other building specialists, such as architects, engineers, and a variety of trade workers, such as stonemasons, electricians, and carpenters. Projects may require specialists in everything from structural metalworking and painting, to landscaping, building roads, installing carpets, and excavating sites. Depending on the project, construction managers also may interact with lawyers and local government officials. For example, when working on city-owned property or municipal buildings, managers sometimes confer with city council members to ensure that all regulations are met.

For projects too large to be managed by one person, such as office buildings and industrial complexes, a construction manager would only be in charge of one part of the project. Each construction manager would oversee a specific construction phase and choose subcontractors to complete it. Construction managers may need to collaborate and coordinate with other construction managers who are responsible for different aspects of the project.

To maximize efficiency and productivity, construction managers often use specialized cost-estimating and planning software to effectively budget the time and money required to complete specific projects. Many managers also use software to determine the best way to get materials to the building site. For more information, see the profile on cost estimators.

Architects plan and design buildings and other structures.

Architects typically do the following:

• Seek new work by marketing and giving presentations
• Consult with clients to determine requirements for structures
• Estimate materials, equipment, costs, and construction time
• Prepare, design, and structure specifications
• Direct workers who prepare drawings and documents
• Prepare scaled drawings of the project
• Prepare contract documents for building contractors
• Manage construction contracts
• Visit worksites to ensure that construction adheres to architectural plans

People need places to live, work, play, learn, worship, meet, govern, shop, and eat. Architects are responsible for designing these places, whether they are private or public; indoors or outdoors; or rooms, buildings, or complexes.

Architects discuss with clients the objectives, requirements, and budget of a project. In some cases, architects provide various predesign services, such as feasibility and environmental impact studies, site selection, cost analyses and land-use studies, and design requirements. For example, architects may determine a building's space requirements by researching its number and types of potential users.

After discussing and agreeing on the initial proposal, architects develop final construction plans that show the building's appearance and details for its construction. Accompanying these plans are drawings of the structural system; air-conditioning, heating, and ventilating systems; electrical systems; communications systems; plumbing; and, possibly, site and landscape plans.

In developing designs, architects must follow building codes, zoning laws, fire regulations, and other ordinances, such as those requiring easy access by people who are disabled.

Computer-aided design and drafting (CADD) and building information modeling (BIM) technology have replaced traditional drafting paper and pencil as the most common methods for creating designs and construction drawings.

Architects also may help clients get construction bids, select contractors, and negotiate construction contracts.

As construction proceeds, architects may visit building sites to ensure that contractors follow the design, keep to the schedule, use the specified materials, and meet work-quality standards. The job is not complete until all construction is finished, required tests are conducted, and construction costs are paid.

Architects often work with workers in related professions. For more information on these occupations, see the profiles on civil engineers, urban and regional planners, interior designers, and landscape architects.

Electrical and electronics installers and repairers install, repair, or replace a variety of electrical equipment in telecommunications, transportation, utilities, and other industries.

Electrical and electronics installers and repairers typically do the following:

• Prepare cost estimates for clients
• Refer to service guides, schematics, and manufacturer specifications
• Repair or replace defective parts, such as motors, fuses, or gaskets
• Reassemble and test equipment after repairs
• Maintain records of parts used, labor time, and final charges

Electrical and electronics installers and repairers work on complex pieces of electronic equipment.

Automated electronic control systems are becoming increasingly complex. As a result, repairers use software programs and testing equipment to diagnose malfunctions. Among their diagnostic tools are multimeters--which measure voltage, current, and resistance--and advanced multimeters, which measure the capacitance, inductance, and current gain of transistors.

Repairers also use signal generators, which provide test signals, and oscilloscopes, which display signals graphically. In addition, repairers use handtools such as pliers, screwdrivers, soldering irons, and wrenches to replace faulty parts and adjust equipment.

Commercial and industrial equipment electrical and electronics repairers repair, test, adjust, or install electronic equipment, such as industrial controls, transmitters, and antennas.

Electrical and electronics installers and repairers of transportation equipment install, adjust, or maintain mobile communication equipment, including sound, sonar, security, navigation, and surveillance systems on trains, watercraft, or other vehicles.

Powerhouse, substation, and relay electrical and electronics repairers inspect, test, maintain, or repair electrical equipment used in generating stations, substations, and inservice relays. These workers may be known as powerhouse electricians, relay technicians, or power transformer repairers.

Electric motor, power tool, and related repairers--such as armature winders, generator mechanics, and electric golf cart repairers--specialize in installing, maintaining, and repairing electric motors, wiring, or switches.

Electronic equipment installers and repairers of motor vehicles install, diagnose, and repair sound, security, and navigation equipment in motor vehicles. Motor vehicle installers and repairers work with an increasingly complex range of electronic equipment, including DVD players, navigation systems, and passive and active security systems.

Electrical and electronic installers and repairers may specialize, according to how and where they work:

Field technicians often travel to factories or other locations to repair equipment. When equipment breaks down, field technicians go to a customer's site to repair the equipment. Because repairing components is a complex activity, workers on the factory floor usually remove and replace defective units, such as circuit boards, instead of fixing them. Defective units are discarded or returned to the manufacturer or a specialized shop for repair.

Bench technicians work in repair shops in factories and service centers, fixing components that cannot be repaired on the factory floor. These workers also locate and repair circuit defects, such as poorly soldered joints, blown fuses, or malfunctioning transistors.

Home entertainment equipment installers and repairers set up and fix household audio and video equipment, such as televisions, stereo components, and home theater systems.

Home entertainment equipment installers and repairers typically do the following:

• Install electronic equipment and devices, such as televisions and speaker systems
• Inspect malfunctioning equipment and devices
• Read and interpret electronic circuit diagrams, specifications, and service manuals
• Take apart equipment and repair or replace loose, worn, or defective parts and wiring
• Calibrate, tune, or adjust equipment and instruments to specified performance levels
• Test equipment and parts after installing or repairing them
• Make service calls to customers' homes or bring equipment or parts to shops for major repairs
• Teach customers the safe and proper use of audio and video equipment

Home entertainment equipment installers and repairers, also called service technicians install, troubleshoot, and fine-tune sound and picture quality, ensuring that a client's home entertainment system works at its peak capability.

They work on many types of equipment, including customer's televisions, stereos, satellite dishes, and surround-sound systems. They may specialize in one or many kinds of products.

When working on small portable equipment, such as DVD players and video cameras, technicians generally work in central repair shops. When repairing less mobile equipment, such as big-screen televisions, however, they must travel to the customer's location. If the job is overly complex, technicians may take the equipment back to the shop for further work.

Service technicians' work involves many different tools. For example, they may use basic handtools, such as screwdrivers, hammers, and wrenches, to disassemble and reassemble components.

They may also use more sophisticated diagnostic tools, including multimeters, voltmeters, oscilloscopes, and digital storage scopes, to identify electronic malfunctions, such as short circuits and failed capacitors. Because of the growing complexity of home entertainment systems, service technicians frequently consult schematics and manufacturers' specifications for instructions on how to repair certain problems.

Most service technicians keep records of bills, payments, parts used, and hours worked. Technicians also show customers how to use new equipment or explain the repairs they made.
