Electricians are responsible for the safe operation of electrical systems. They test, install, and repair electrical equipment and fixtures. They also follow local and national building codes. Licensed electricians are required by law to be registered and certified. In order to obtain a license, electricians must complete a training program, pass an examination, and meet continuing education requirements.

Because most buildings have electrical systems, electricians are often needed to install or replace existing ones. The use of alternative energy sources like solar power is expected to increase demand for electricians. In order to harness the power generated by such renewable sources, electricians will connect them to homes and power grids. Government incentives may also boost the number of electricians employed in the field.

There are two main categories of electricians: linemen and wiremen. Linemen deal with higher voltage electrical systems, while wiremen work on lower voltage systems inside buildings. In addition to using a variety of testing devices, wiremen use hand and power tools to safely perform their duties. They also plan the layout of electrical wiring and install electrical fixtures. They are required to follow national electrical code regulations and safety standards.

An electrician’s training program usually includes on-the-job training. Generally, electricians train through apprenticeships, but some enter directly into the field from technical school. In most states, electricians must have a state-issued license. You can contact your local electrical licensing board for more information about this.
