An electrician is a professional who specializes in wiring electrical systems, such as buildings and transmission lines. They may also install new electrical components and maintain existing infrastructure. This professional may be found in both domestic and commercial settings. Some electricians work for utilities and construction firms. Other electricians may be independent contractors or work as part of an electrical engineering team.
To become an electrician, you must have a basic education and have good practical skills. You may also have to take an aptitude test and pass a drug test. Alternatively, you can attend vocational schools that focus on apprenticeship training. In some states, such as California, it is compulsory to register as an electrical apprentice. This process involves filling out a form and paying a small fee.
To complete a job, an electrician must use a variety of hand and power tools. Tools used in electrical work include conduit benders, wire strippers, drills, and saws. They also use tools like voltmeters, ammeters, and thermal scanners to troubleshoot problems.
The electrical industry is constantly evolving, so it is essential to stay abreast of developments. For instance, solar energy is becoming more popular and electricians may be needed to install solar panels on homes. Other new technologies include fiber optic technology and LAN cables. As a result, electricians must be flexible and open to new situations.
