An electrician is a professional who specializes in wiring buildings, transmission lines, and stationary machines. His work may also involve the installation of new electrical components and the maintenance of existing electrical infrastructure. An electrician may work in a variety of settings, including residential, commercial, or industrial. Some electricians may also be self-employed.
As a result, the electrical field is constantly evolving. For example, solar energy is becoming more popular, and electricians may be called upon to install solar panels on roofs. Additionally, new technologies such as fiber optic technology and LAN cables are gaining popularity, and electricians must adapt to these changes.
Licensed electricians are required by state law to have a certain level of electrical competence. In the UK, qualified electricians must have electrical knowledge at Level 3. Qualified electricians are also required to hold a card that allows them to work in controlled areas. In many states, electricians must be state-certified, but requirements may vary.
Electrical work is dangerous and requires the ability to focus on specific tasks. While many jobs may be relatively simple – like installing a new outlet or a lighting fixture – there is a significant risk of injury. In addition, electricians may have to climb ladders or crawl through dark basements.
