Commercial electricians work on the wiring and control equipment mechanisms from which electricity is generated and dispersed. The commercial electrician is responsible for execution of a wide range of tasks involving commercial electrical installation, maintenance, and repair. They handle the power systems for businesses, factories, public works, government agencies, and other establishments.
Commercial electricians must be experts installing, maintaining, and repairing security lighting, surge protection, code corrections for signs, parking lighting, equipment upgrades, inspections and testing, voltage wiring, motors and transformers, data and phone wiring, card access systems, warehouse HID and florescent lighting, halogen, sodium, and metal halide lighting; among other skills and knowledge.
Commercial electricians need be able to read schematics and blueprints. These technical diagrams lay out where all circuits, outlets, load centers, panel boards, and all other electrical system mechanisms are located within the system. Now, they must be able to install, connect, maintain, and repair all wiring, circuit breakers, transformers and other components laid out on the blueprint. Electricians use tools like conduit benders, hand tools, ammeters, ohmmeters, voltmeters, harmonics testers, and other testing equipment to measure safety and compatibility, as well as install and test lines and gear.
Large corporations and businesses employ commercial electricians who are able to advise and oversee more multifaceted work to keep company in safety compliance and to ensure business isn’t disturbed. Commercial electricians could collaborate with engineers, engineering technicians, line installers, industrial machinery mechanics, and maintenance workers. Dependent on the state they’re employed, if the commercial electrician is a contractor, they must be licensed. Seven years’ experience is required to hold master level card; a degree in electrical engineering is preferred.
Some electricians learn their trade through vocational schools, uniting on-the-job-training with classwork. Apprentice programs last about 4 years and consist of over 140 classroom hours learning electrical systems, theory, code requirements, how to read blueprints, and safety. Then they have about a year of on-the-job-training. Openings exist in large business and government, but to handle their complex systems, commercial electricians are expected to have a bachelor’s degree. Continuing education should be ongoing throughout the career of a commercial electrician, as different technologies continually emerge.
