Industry jobs (about electrician)
Electrical contractors employ workers in many capacities, determined by their level of training and experience. Some common jobs include:
Apprentice Electrician ? Receives on-the-job training and classroom instruction from licensed journeymen or master electricians about how to install, modify, repair, and maintain power and lighting systems. Most apprentice programs last 3 to 5 years and apprentices earn wages during this training period.2
Journeyman Electrician ? Installs, modifies, repairs, and maintains power and lighting systems. Reads blueprints, terminates cable, and installs and troubleshoots control wiring from drawings. Has completed the apprentice program and holds a journeyman's license (according to state requirements) and supervises apprentices.
Estimator ? Calculates a project's duration and cost, including materials, overhead, and labor. This estimate is often submitted as a bid on a project and serves as a scheduling and budget guideline as the project proceeds.
Project Supervisor ? Oversees workforce to encourage safe and high-quality installations. Monitors progress to meet project deadlines. Submits required reports and forms.

Laying electrical wiring in the home
Although many people isolated attempts to control the domestic installations, usually professional help is highly desirable especially in more complex cases. As far as changing a light bulb or perform other similar tasks require more visits electrician so much already in the case of laying wires or installation of distribution are more complicated. Isolated executed electrical installations can make later, at the stage of operational problems arise, for example, through the inclusion of too many devices to the power supply circuit may occur. So let's take care of it, to the more complex work carried out specialist, because working with electricity can be dangerous for inexperienced employee.
Computerization measurement of electricity
Very often in electrical engineering they used different computer programs. They are used not only for the design of electrical networks in even the smallest details, but also makes using them you can monitor the status of installations already in operation. Thanks to computer programs monitor the status of the electrical system has become almost a snap. Hold install the software with specific functions allows, for example, to measure the resistance of the electrical installations and other properties and measured in a direct way would have to be carried out in a more complicated formula.
