Electricians launch their careers by attending technical school. In technical school, they learn to read blueprints, mathematics, electrical theory and local building codes. Their primary role is to help keep the safe and reliable flow of electrical current to electrical equipment and other outlets. The secondary roles are dependent on the sectors in which they are employed, their levels of experience and the specific jobs they attend. Although they have much in common, there are many differences in the duties handled by electricians. The roles depend on the career path chosen.
· Residential repair electricians
Many of the electricians focus on repairing electrical systems in residents. With the passage of time, the wiring can become obsolescent or defective, homeowners may require outputs in new locations or circuit breakers may become outmoded to handle the current demands. Older residential homes are undergoing renovations; therefore, they play an important role of rewiring the entire house. They may need to coordinate with other professionals including air conditioning technicians, plumbers and carpenters.
· Commercial electricians
A commercial electrician specializes in the installation and repair of electrical systems in commercial buildings including offices and stores. The time arises when the business needs to increase its computer equipment. The offices may therefore need new wiring to cater for these power requirements. The store may need to relocate its cash register or require a lighted sign. They play an important role in handling such matters for offices and retailers. Some time they may need to work with other professionals including alarm system technicians or elevator installers.
· Industrial electricians
Many electricians work within the industrial setting rather than residential settings. They often undertake multiple roles. For instance, in the case of automated production lines, they may repair the robotics while at other times they may repair motors or generators. In the event of new electrical equipment arriving, it is often their responsibility to install them by rewiring existing systems. Furthermore, they may undertake routine maintenance of the plant's equipment.
· New construction
Electricians who are involved in new constructions work from blueprints that builders or architects have produced. The blueprints inform them where the switches, outlets, lighting fixtures and circuit breakers need to go. Therefore, they determine the way the wiring needs to run. They install conduits that help to hold the wiring when necessary and run the electrical wires to connect them. Those who are serving their apprenticeships may not fill these roles unless they are supervised. The licensed practitioners handle these tasks without supervision.
