An electrician specializes in electrical wiring and maintenance of buildings, transmission lines, and stationary machines. They may also be involved in the installation of new electrical components and infrastructure, and may work on repairs and upgrades to existing electrical systems. There are many different types of electricians, with different levels of training and responsibilities.

Electricians read blueprints and use power tools to install wiring and components. They also use ammeters and voltmeters to determine current levels and conduct tests. These professionals must be familiar with electrical safety regulations. They also must be skilled in dealing with customers. Electrical workers should be courteous and able to answer questions.

Electricians generally work on construction sites. They may also work for business owners or landlords. They may have to provide estimates for their work or communicate progress to clients. Depending on where they live, electricians can be self-employed or employed by a company. During the construction process, they may be responsible for installing new electrical components and maintaining the existing infrastructure.

An electrician’s training program combines classroom and on-the-job training. On-the-job training involves working on job sites and being paid by the hour. An apprentice’s wages start at 40 percent of the hourly rate of a journeyperson, but increase as they progress.
