Electricians install, test, and maintain electrical systems.
Electricians chose to work either in construction or maintenance. Many work in both. In general, construction electricians assemble and install electrical systems. Maintenance electricians maintain and repair systems.
Electricians may install fiber optic or coaxial cables for computers and telephones. They connect motors to electrical power. They may also install electronic controls for industrial equipment.
All electricians use tools such as:
- Power tools
When working on complex electronic devices, they may consult engineers or industrial machinery repairers. Some electricians have helpers. Electricians teach helpers how to complete tasks and supervise their work.
Construction electricians read blueprints of circuits, outlets, and other equipment. Electricians use this information to plan how they will install the wiring.
When the wiring is finished, electricians test that all the circuits work properly. They follow the national electric code as well as state and local building codes when installing systems.
Maintenance electricians keep electrical systems and equipment in good working order. They inspect equipment and fix any problems. They also check equipment for safety. They may install new electrical equipment.
When breakdowns occur, they work to find the problem and make the repair. They use equipment such as oscilloscopes to diagnose problems. They may change items such as circuit breakers, fuses, electrical components, or wire.
