Electrical

Electricians read blueprints to install electrical systems in factories, office buildings, homes, and other structures. They may also install coaxial cable for television or fiber optic cable for computers and telecommunications equipment.

Electricians who specialize in residential work may install wire and hardware like electrical panel boxes, receptacles, light switches, and electrical light fixtures in a new home or replace outdated fuse boxes. Those who work in large factories as commercial electricians may install or repair motors, transformers, generators, or electronic controllers on machine tools and industrial robots. They use numerous hand tools, operate power tools, and use electric testing meters such as ammeters or test lamps.

Electricians may begin their career as a helper and then enter a formal training program becoming an apprentice, after formal training electricians must pass a written test to obtain an Electrician’s license. This license is required in almost every community in the United States to ensure all electrical installations meet the National Electrical Code—standards for safety. Electricians must use their athletic capabilities. Hand/Eye coordination, manual dexterity, and physical balance are important for climbing ladders or operating power tools. Thanks to safety training programs, employers have greatly reduced accidents on the job. Electricians perform many tasks outdoors and indoors, working closely with other trades.
