Electricians install, maintain, and repair electrical power, communications, lighting, and control systems in homes, businesses, and factories.
Electricians typically do the following:
- Read blueprints or technical diagrams
- Install and maintain wiring systems
- Inspect electrical components
- Identify electrical problems
- Repair or replace wiring, equipment, or fixtures
- Follow state and local building regulations
Almost every building has an electrical power, communications, lighting, and control system that is installed during construction and maintained after that. These systems power the lights, appliances, and equipment that make people’s lives and jobs easier and more comfortable.
Installing electrical systems in newly constructed buildings is often less complicated than maintaining equipment in existing buildings because electrical wiring is more easily accessible during construction. Maintaining equipment and systems involve identifying problems and repairing broken equipment that is sometimes difficult to reach. Maintenance work may include fixing or replacing parts, light fixtures, control systems, motors, and other types of electrical equipment.
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 conduit 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, thermal scanners, and cable testers to find problems and ensure that components are working properly.
