Wikipedia about responsibilities of electricians
The master electrician supervises and is responsible for all other electricians working on any construction or installation project. Only the master electrician can pull the permits with the electrical authority, and they can only be registered with one electrical contracting company at any one time. Other electrical duties performed by any electrician include:
Inventory and repair and maintenance of all lighting fixtures, cables, effects, power distribution, dimmers, networking and lighting control consoles.
Organization and purchasing of all consumables including color gel, gobos, Sharpies, and gaffer tape.
Planning and implementing of the cabling (circuiting) of lights and electric power distribution.
Documenting and tracking of all circuiting, addressing, and system configuration in cooperation with the Lighting Designer.
Patching assignments of the control console based on the paperwork generated by the lighting designer and the planned circuiting.
Occupational safety and health of workers and operational decisions as the head of the electrics department.
Industrial classification of electricians - by Wikipedia
Electrical contractors are generally classified by three major types of work performed.
"Outside" or "line" contractors are responsible for high-voltage power transmission and distribution lines. Line contractors build and maintain the infrastructure required to transport electricity generated at a power plant through a series of high-voltage lines and substations before it is used to power facilities, buildings, and homes.
"Inside" electrical contractors provide electricity to any structure within a property?s boundary lines, including outdoor lighting or substations. Under current construction specification guidelines, "inside" electrical contractors can serve as prime contractors for all electrical and cabling design, installation, and maintenance for commercial, institutional, and residential buildings. Projects also include Database Centers/Infrastructure and Pharmaceutical Work.
"Integrated building systems" (IBS) or "Voice/Data/Video" (VDV) electrical contractors work primarily with low-voltage installations such as back-up power, climate controls, wireless networks, energy-efficient lighting, telecommunications, fiber optics, and security systems. IBS contractors are particularly skilled at integrating these system controls to work together for maximum energy efficiency and building performance.
Job opportunities in large enterprises
Large industrial plants require continuous supervision by electricians. In such places, electrical work, after-hour, including the usually public holidays and so on. Often continuity of production makes the conduct of such processes is profitable. Production plants are often places where electricity specialist can find a well-paid job. This involves a number of responsibilities for the most number of installations. Moreover, work in the industry can find a lot of people, because the large volume production is accompanied by high employment, also in the field of electrical engineering.
